Uusimaa Biking Trails

LOHJANHARJU MTB ROUTE

Nummela 11 km cycling loop is about 11.4 km as a circuit through Nummela in Vihti, tying together the town’s sports belt, the wooded ridge at Nummelanharju, Pajuniityn recreation fields, and the Enäranta shoreline on Lake Enäjärvi. Visit Vihti’s Nummelanharju page describes wide, well-kept gravel fitness trails (pururata) of about 2.5–10 km on the dry pine heath of the ridge—shared by cyclists, walkers, and runners—with some hilly sections and lighting on part of the network; winter grooming turns many of those corridors into ski tracks, and live trail status is published via the municipality’s winter sports service linked from that page(1). The City of Vihti places Nummela alongside Nuuksio National Park and municipal hiking, canoeing, and cycling networks as a county where nature stays close to everyday life(2). Away from the ridge, the loop uses local streets and paths past schools, ball fields, and services, then opens into Pajuniityn MultiGolfPark and obstacle-course pockets profiled on Visit Vihti’s Pajuniityn Bootcamp page(4). For a broader picture of long road and MTB circuits that touch Vihti, Jälki.fi’s Vihti area index lists community-contributed rides from fatbike loops toward Hanko to Sääksi-area MTB classics—useful if you want to stitch a longer day from the same town(3). Starting from the Nummela station block, the first kilometres thread the Kaarenkierros corner near Väinämöinen sports courts, pass Nummelan työväentalo, and climb toward the Nummelanharju cluster where Vihdin uimahalli, Nummelanharjun kuntoportaat, and the outdoor gym on the NLA fitness loop sit within a few hundred metres of each other. That is the natural place to join Kaarenkierroksen lähiliikuntareitti for a micro-loop or to peel off toward Nummelan kuntorata 5 km, valaistu, Nummelan kuntorata lentokentänpuoli, and Tykilumilatu when you want a lit gravel lap or winter ski geometry instead of this mixed loop. After the airport-side fitness strip—where winter crews sometimes flood a 750 m tour-skating lane on the airfield—the line drops toward light-industry roads and Pajuniityn, passing padel halls and outdoor courts before Muistolanpuisto’s gym island, Linnanniitun kuntoportaat, and a simple Laavu shelter in the same kilometre band. Multigolf, an obstacle play track, and more ball fields follow as you curve back toward housing. Around Enäranta you ride the lake margin where the public beach, sand court, and skating slab give a clear swim-and-picnic pause on warm days. The northern closing arc crosses Ratapuisto’s artificial turf, Kuoppanummi schools and ice halls, and finally Health Club and station-side gyms—so the ring doubles as a sampler of Nummela’s public sport geography. Treat this as a shared-use community circuit: yield on narrow path shoulders, ring a bell before passing runners on pururata sections, and keep speed sensible where children cross toward Pajuniityn or schools.

K-18 MTB-oikaisu is a very short point-to-point mountain-bike connector—about 1 km on our map—in the Kytäjä–Usmi recreation forests west of Hyvinkää. It threads the same forest-road and path mesh as the city’s three signposted MTB loops (Karhujen, Kytömetsän, and Hyvinkään pyörähdys), so it works best as a cut-through when you are linking those circuits or approaching lakeside rest spots instead of riding the longer way around(1). The line sits in the Natura 2000 woodland between the Iso-Karhun campfire cluster and Kaksoslammien laavu, then carries on toward Latu-Miilun maja at the northern end: you pass the Kaksoslammet lean-to a few hundred metres after the start of this segment, and the ski-club cabin setting at Latu-Miilun maja sits just past the mapped finish—handy for combining with Karhujen pyörähdys, Kolmen lammen kierros on foot, or the Usmi ski loop in winter. City materials do not give this exact connector its own trail page; for how the wider MTB network is marked and managed, start from the City of Hyvinkää’s mountain-biking hub and the Karhujen pyörähdys trail page, which describe bear-on-blue waymarks, counter-clockwise looping, gravel-leaning surfaces, and parking at Usmi beach(1)(2). The same network is mirrored on Luontoon.fi for map browsing(4). The Kytäjä–Usmi outdoor area overview lists roughly 27 km of maintained MTB lines and the mix of lean-tos, dry toilets, and firewood policy across the wider trail system—expect similar etiquette on connectors(3). Experienced riders threading a longer tour through Usmi often stage from Hyvinkää station or Sveitsi, roll toward Iso-Karhu, and shape loops toward Kiiskilampi or Petkelsuo; one detailed Jälki.fi write-up notes varied forest path with short technical pitches near Iso-Karhu before continuing toward Kiiskilampi and Kaksoslammet—useful pacing context for how this terrain feels even on a kilometre-long link(5). For fat bikes, e-MTBs, or gravel rigs without your own transport, Sveitsi Rent at Hyvinkää’s Sveitsi sports cluster takes online bookings and highlights the area’s ride network(6). Hyvinkää lies in Uusimaa inland from Helsinki; treat this connector like any other forest tyre track—yield to hikers where tread is shared, carry out litter, and confirm campfire rules when warnings apply(3).

This short mountain-bike line sits in the Oittaa outdoor area on the southern shore of Lake Bodom in Espoo, Uusimaa, threaded beside the groomed ski and fitness corridor the city maintains through the same woods. The City of Espoo describes undulating singletrack with partly gravelled tread, some rock, and normal forest floor, all built next to the winter ski and summer fitness track(1). The mapped ride is about 1.2 km end to end; the city’s text often rounds to 1.3 km for the same feature(1). Visit Espoo’s Oittaa outdoor area page fills in the bigger picture—beach life on Bodomjärvi, restaurant and sauna, disc golf, and how bus 246 / 246K links the site to Espoon keskus—plus seasonal equipment rental from the leisure-centre café or beach hire desk, including fatbikes in summer(2). Along the trace you are never far from the recreation yard: outdoor gym stations at Oittaan uimarannan ulkokuntosali and Oittaan ulkokuntoiluvälineet, the large Oittaan frisbeegolfrata centre, several parking lots serving the beach and trails, and Oittaan keittokatos for a longer stop with a cooking shelter. Expect other trail users where the MTB line meets the shared fitness and ski network; the adjacent Oittaan kuntorata 2,8km (GPS) is the familiar gravel fitness loop walkers and runners use in summer(1)(2). Oittaan luontopolku is a separate, signposted nature loop meant for—Espoo’s mountain biking routes hub asks riders to stay on designated MTB tread and leave nature trails for walking(4). For a skills-and-rolling-practice outing with company, Suomen Latu runs weekly fatbike and MTB group rides staged from Oittaa; Ne Tammelat’s account of one beginner-friendly session highlights how coaches use short climbs, roots, and wooden features to build confidence on local forest soil(3)(5). Regionally, that same hub connects Oittaa with Espoo’s longer MTB offerings, including the roughly 4 km line in Espoo Central Park and the roughly 110 km Reitti 2000 backbone across the capital region when you want a bigger day after sampling this trail(4).

Kelkkalantie pyöräilyreitti is about 6.9 km point-to-point through Nuuksio National Park on the Vihti side of the lake plateau, mostly on the forest maintenance road known in park materials as Kelkkalan huoltotie together with neighbouring permitted cycling corridors such as Kurjolammentie(2). Metsähallitus reminds visitors that in the national park you may cycle only on routes marked for cycling—mainly gravel roads, low-standard cart tracks, and short path sections that suit a normal bike if you are ready to walk short steep or rooty bits(1)(2). The wider Nuuksio cycling network is not separate bike infrastructure; national cycling route 2 crosses the park from Siikajärvi past Haukkalampi toward the Salmi area(2), and this segment links the Valklampi trailhead cluster with Kattila and Haukkalampi amenities. For closures, etiquette with other visitors, and the definitive map, start from the Nuuksio cycling pages on Luontoon.fi(1). The City of Vihti adds municipal outdoor context on its retkeily pages(3). Vihti sits on the national-park edge and shares many of these trailheads. Most riders begin from Valklammentien pysäköintialue or Kurjolammentien uusi pysäköintialue, then roll past Tikankolo vuokratupa with Saarilampi tulentekopaikka and Saarilampi telttailualue about a kilometre out—handy for a swim stop or picnic before Oravankolo vuokratupa and Oravankolon sauna appear in the spruce forest around 2.4 km. The middle kilometres climb and dip through typical Nuuksio moraine woodland before Kattilan alempi pysäköintialue, Kattilan uusi pysäköintialue, Kattilan rantasauna, Kattila savusauna, Kattila varauskota, Kattila torppa, Kattila ylempi tulentekopaikka, Kattila niityn varattava telttailualue and Haukanholman laituri string together services where many people pause to eat, book a sauna, or launch a small craft. Near the ride’s end, Haukanholman telttailualue, Haukanholman keittokatos, Haukanholman tulentekopaikka, Haukkalampi Haukanpesä varaussauna, Haukkalammen pieni pysäköintialue and Haukkalampi iso pysäköintialue cluster at Haukkalampi—one of the busiest gateways to the park and rich with day-trip infrastructure Jonna Saari describes for winter visits (the same fireplaces, cooking shelters, and reservation saunas matter in summer too)(4). On foot- and bike-friendly connections, Klassarinkierros shares the Valklampi parking and Tikankolo huts; Yhdysreitti Kattila - Mustalampi meets this line at Haukanholman laituri if you want to continue toward Mustalammen keittokatos; Haukkalampi pyöräilyreitti and Haukkalammen saaren polku sit a few hundred metres away at Haukkalampi for short add-on loops. Ride expectantly, brake for hikers on shared sections, and carry a map because these roads are not marked like a city bike path(1)(2). If you need a fatbike or e-fatbike near the park, Suomen luontokeskus Haltia rents them by the hour or day from its shop(5).

The EKP4,2 loop is about 4 km through Espoo Central Park—Espoon keskuspuisto—a mixed woodland and rock belt between the sea and the Nuuksio uplands in Espoo, Uusimaa. Start planning from the City of Espoo trail page for EKP4,2(1), which lists the orange-triangle marking, the start beside Akilleen Maja in Puolarmaari, the optional shorter easier loop, and the clockwise-only rule. The wider recreation portrait of the park—about 880 hectares, leash rules for dogs, and why sensitive rock and mire habitats deserve care—appears on the Uudenmaan virkistysalueyhdistys page for Espoo Central Park(3). A spring 2024 City of Espoo article adds practical terrain-care reminders for mountain bikers, including why lichens, roots, and wet soils need gentle tyre tracks(2). At the Puolarmaari trailhead you step straight into the city’s outdoor-recreation belt: the trace passes Puolarmaarin frisbeegolfrata, Puolarmaarin ulkokuntoiluvälineet, Puolarmaarin ulkoilukeskus/koripallokenttä, Puolarmaarin tekojää, Puolarmaarin ulkoilukeskus/ministadion, and Puolarmaarin ulkoilukeskuksen ulkokuntosali before looping deeper into the forest. Puolarmaarin Pysäköintialue is the natural place to stage a car visit. The published start is next to Akilleen Maja; the service address on the city unit page is Kylänvanhimmanpiha 6, 02210 Espoo(1). Expect a proper hand-built mountain-bike character: variable forest floor, roots, and rocky shelves where friction changes fast in wet weather—reason enough to scout unfamiliar drops slowly. The main line is marked with orange triangles; an easier shortcut of about 2 km follows blue dot markings under those triangles from a junction roughly 200 m from Akilleen Maja(1). Ride the main ring clockwise only(1). Volunteer maintainers publish practical trail etiquette alongside the city: two outdoor fitness-route crossings need calm speed and yielding, pedestrians may share the tread, and ringing out a friendly warning before passing is standard practice(4). On the north side of the loop, about three kilometres into the lap, you pass Espoon keskuspuiston ulkokuntoiluvälineet—handy if you want pull-up bars or other body-weight work after the ride. The same park threads together many other layers of movement. On foot, Espoon keskuspuiston luontopolku (Tikankierros) explores signposted nature-trail scenery nearby. In winter, lit ski corridors such as Keskuspuisto - Latokaski (4km/p+v/valaistu) and Puolarmaari (1,4km/p+v/osittain valaistu) share trailheads with summer users; in warm weather, Keskuspuisto - Latokaski ulkoilureitti and Espoon Keskuspuisto / Kuntorata (4,3km) (GPS) offer walking and running alternatives around overlapping woods. Treat every junction as multi-use: match your speed to whoever else is on the path.

For the marked trail corridor and map entry maintained in the capital region, start from the City of Helsinki’s Reitti 2000 listing on the service map(1). Visit Espoo’s cycling feature introduces the wider loop through Nuuksio landscapes and names Suomen luontokeskus Haltia among good stops(2). The biking route on our map is about 64,7 km as one continuous ride starting in the Vihti area and running west toward the Lohja direction along the same Reitti 2000 system. In headline terms the full Reitti 2000 is often described as roughly 110 km on a metropolitan loop through Helsinki, Espoo, Vantaa, and Vihti(2)(3), while the segment here is useful if you want a long day ride or the western leg without committing to the entire circle from Laakso. Early kilometres weave Takala and Kattila forest and the Salmi recreation area: you soon pass Takalan laavu and meet Salmen ulkoilualue with cooking shelters, beaches, and parking at Paratiisi, plus shorelines at Iso-Parikas and Vähä-Parikas—easy places to pause for food or a swim when conditions allow. The walking route Salmen ulkoilualue - Ulkoilureitti 10,7 km (Tapio trail) and the short Salmintie pyöräilyreitti share many of the same outdoor points, and the hiking path Takalan polku branches toward Kattila with reservable kota, saunas, and tent spots if you want to stitch in an overnight. Toward Nuuksio the trail character shifts between gravel outdoor routes and shorter technical trail stretches; several sources note a notable trail section with roots and rocks between Lakisto and Ruskela on the full loop(3), and sensible mountain bike or gravel tyres are a practical choice throughout. Near Haukkalampi, cycling is restricted on the narrow footpath leg—riders follow the signed gravel detour along Kattilantie toward Haltia(3). About 30 km along the route you reach Solvalla Sport Institute, Suomen luontokeskus Haltia, Haltia parking, and Solvallan uimapaikka; Sorvalammen uimaranta lies a little farther east in Espoo for another swim stop(2). Beyond Haltia the ride continues on forest and gravel roads with steady elevation changes; Visit Espoo warns of steep climbs and descents toward Pirttimäki for riders who complete the Luukki–Haltia–Luukki circuit on the full network(2). The western end of this segment approaches built-up Lohja; Kantakaupungin rantareitti links toward central Helsinki if you plan onward urban riding(3). Marking is widely described as blue-and-white ribbon and signposting, with occasional unclear junctions where a GPS track or map helps(3)(4). READY / RUN’s fastest-known-time notes reinforce that on the ground markings and maps do not always match perfectly(4). Uusimaa ties these municipalities together; Vihti is the administrative home for this catalogue entry. For closures, etiquette near hikers, and any service changes, rely on the city and park pages(1)(2) rather than third-party tracks alone. Equipment hire and guided fatbike options near the Nuuksio section are summarized under Where to rent equipment and Guided tours, each with operator booking pages linked.

Visit Raseborg introduces the area’s showcase mountain-bike destination at Fiskars: fourteen volunteer-maintained lines in four colour-coded difficulty bands, with the wider destination marketing positioning Fiskars as the place Raasepori expanded MTB access in recent seasons(1). Trail Center public pages spell out how Finland’s first purpose-built trail centre around the Fiskars ironworks spreads more than fifty kilometres of mostly natural singletrack plus a pump track, marks grades from easy green through black technical lines, and directs riders to the Paja-Aukio start beside Kuparivasarantie while parking sits at the assembly-hall lot on Fiskarsintie(2). The same team stresses that riding is at your own risk, difficulty and surface conditions change with the weather, and there is no round-the-clock grooming, so checking their social updates before you load the car matters(2). Fiskars Village layers visitor context: over sixty kilometres of playful MTB trail, rental desks in Craft Square with Canyon full-suspension, hard-tail, fat and e-mountain bikes, and the option to ask about guided rides for pre-booked groups(3). On our map this route is about 13.2 km as one non-loop leg through the network around Raasepori in Uusimaa. During the opening kilometres you pass the sports cluster next to the village—Fiskarsin Tenniskerhon padelkentät, Fiskarsin Urheilukenttä, Fiskarsin kaukalo, Fiskarin skeittipuisto, and a little farther along Fiskarsin tenniskentät (4). Beyond that village fringe the line heads into rockier forest tread typical of southern Finland. Bikeland’s notes on the Rövarberget option describe roughly thirteen kilometres, a few hundred metres of cumulative climbing, sustained technical stone and root sections, a viewpoint from the water tower, and a realistic hobbyist duration near two hours on a 120–140 mm trail bike(4); that profile matches the length and demanding character you get on this mapped centre route even though the centre publishes many optional connectors. Fiskars Bike Rental runs seasonal online booking from Kuparivasarantie with morning, evening, and full-day Canyon, fat, and e-MTB slots when the season desk reopens; the shop traditionally pauses between seasons and posts reopening windows on its Johku storefront(5). Mechanics and quick fixes are handled in the village by independents such as Pedal Pukus per the Trail Center listings(2).

Vierumäen XCO-rata is a cross-country Olympic style mountain-bike loop in Vantaa’s Vierumäki outdoor block on the capital-region fringe, maintained by Korson Kaiku mountain bikers on city-leased land(1). The mapped line is about 3.3 km as one full lap; club materials sometimes describe the same circuit nearer to 4 km because of event layouts or rounding. Planning began in autumn 2012 and construction with initial marking finished in summer 2013; sign graphics were developed together with Metropolia University of Applied Sciences, while the club still asks the city for permanent posted guidance(1). From 2021 onward part of the line crosses a nature reserve: you must stay on the marked XCO line and not shortcut onto other paths so the track can remain open(1). The route starts from the Vierumäki recreation parking at Huuhkajatie 1, 01450 Vantaa. Beside the lit fitness-trail side of the lot, an information board shows the course map(1), matching the service point the City of Vantaa lists for the 2.8 km fitness trail at the same address(2). Early metres brush the Vierumäki school’s outdoor sports cluster before the line dives into pine forest paths. The circuit adds purpose-built features—banked berms, log rides, rock gardens and modest drops—with easier ride-arounds on the hardest tricks(1). For atmosphere on damp rock and root, Jaakko MTB’s write-up of a Korson Kaiku weekend here explains how quickly grip changes after rain(4). The same Huuhkajatie parking is the free, time-unlimited Korso MTB event trailhead in MTBreitti’s KORSO write-up(3), so drivers and riders often share this hub. You can pair laps with Vierumäen kuntorata 2,8km, valaistu for a running or walking warm-down or with Vierumäen hiihtolatu 2,8km when winter tracks are groomed; both connect on the shared outdoor corridor near Vierumäen kuntoradan ulkokuntoilupaikka. Korson Kaiku carries accident insurance for the XCO line, reports vandalism to the police when needed, and welcomes damage reports by email through club channels(1).

This signed sightseeing loop in Kirkonkylä, Vihti, in Uusimaa is about 8.6 km end to end as one continuous ring; brochures and tourism copy often round it to about 9 km. For downloadable maps and the current route package, start from Visit Vihti’s guided cycling routes hub(1). A 2021 local write-up quotes the municipality’s sport lead describing the Kirkonkylä line as one of two new “get to know your home village” cycling products (the other is in Nummela): roughly twenty stopping points introduce local sights, five or six of them carry on-ground guide signs, colour coding separates the sights on printed maps, and QR codes in the field were being added so riders can send feedback. The piece notes start mats at the Kirkonkylä sports area maintenance building off Nietoinkuja and a finale at a playground that hosts short outdoor exercise stations(2). Riding here feels like a town-scale circuit rather than backcountry singletrack. From the Nietoinkuja sports cluster you quickly pass Parkour-puisto Kirkonkylä, Vihdin kirkonkylän urheilukenttä, Vihdin kirkonkylän liikuntahalli, Kirkonkylän luistelurata 400 m, Urheilukentän ulkokuntoilupaikka, and Vihdin kirkonkylän tenniskenttä—useful if you want a warmup or a family pause before rolling on. Two swimming beaches, Haudankallion uimaranta Vihti and Vihdin kirkonkylän uimaranta, sit beside Kirkkojärventie less than a kilometre into the loop; Vihdin beacvolleykentät lies a little farther along the shore band. Niemenharju–Niuhala–Kyläaukio style streets link you toward Liikuntakeskus Poseidon and Balanssi Vihti, then longer straight east-ish legs along Nurmijärventie bring you past Vihdin työväentalo Puistola and Männikön hiekkakenttä before the line turns back toward schoolyards and the evening-sports pocket around Pappilanpellon koulun hiekkakenttä, Pappilanpellon koulun liikuntasali, Vihti kk kaukalo, and Vihti kk luistelukenttä. If you want to stitch outings together, Kirkonkylän kuntorata Vihti shares the same sports block for a short fitness run, while the national long-distance line Pyöräillen Hämeessä Härkätietä pitkin, Häme touches the Kirkonkylä service strip on its way west—handy context if you are planning a longer bike tour but still want this loop as a local warm-up. In winter, koira latu Vihti starts within a few hundred metres of the outdoor-gym corner for skiers who mix modes. Regional background on how Vihti intends to grow walking and cycling networks sits in the municipality’s sustainable mobility planning document on Doria(3). Our own route page mirrors the mapped geometry for on-screen planning(4).

For downloadable GPX, recommended counter-clockwise riding, and a surface-by-surface breakdown, start with the City of Hyvinkää’s Karhujen pyörähdys trail page(1). The Kytäjä–Usmi mountain biking overview on the same municipal site explains how Karhujen pyörähdys, Kytömetsän pyörähdys, and Kytäjän pyörähdys form a linked trio of marked loops you can combine for longer days(2). Metsähallitus also mirrors the route on Luontoon.fi for map browsing(3). The trail is about 10.1 km as a single forest-and-road loop around the Usmi shore area. Published municipal materials describe the “three bears” circuit at roughly 11 km with about 114 m of ascent and an easy gravel-style character on public roads plus forest roads(1); use 10.1 km here for GPS alignment. Hyvinkää sits in Uusimaa, with most of the riding in the Kytäjä–Usmi recreation forests. From the Usmi beach end, you soon work along the lake margin: Usmin uimaranta and the Usminjärven talviuintipaikka make easy orientation points if you arrive by car and walk down to the water. About 1 km into the loop, Iso-Karhun nuotiopaikka and the Iso-karhun Outdoor Grill cluster offer benches, a campfire ring, and a shore-side micro-stop; Kaksoslammien laavu and Iso-Kypärän laavu bookend the twin-pond corner a little earlier, with table groups and lean-to shelter space for a longer lunch. Dry toilets sit near several of these service points—handy on a family outing. Beyond the ponds, a couple of kilometres of paved road aim toward the Hyyppärä riding yards, then narrow forest tracks and wider gravel cut through mixed woodland. Hyvinkään Ratsastuskeskuksen maneesi, Jokirannan ratsastuskoulun maneesi Hyvinkää, Stable Nova / maneesi, and Hyyppärän ratsastusmaneesi all sit within a few hundred metres of the line—expect horses, yard traffic, and occasional surface grit near those yards. About 8.7 km from the start, Latu-Miilun maja marks the Latu-Miilu skiing association cabin; winter weekends sometimes bring a small café rhythm, while summer riders use it mainly as a waypoint toward the lake. Two thirds of the loop overlaps corridors that also belong to the longer Kytäjä circuit, so junctions to Kytömetsän pyörähdys and to walking variants such as Kolmen lammen kierros appear along the eastern segments(1)(2). If you want a regional gravel menu beyond the three signed bear-themed loops, the City of Hyvinkää also promotes Hyvinkään pyörähdys “Plus” as a longer city-and-forest combination that deliberately needs a map or GPS in the urban fringe(2). After the ride, seasonal kiosks at Usmin shore sometimes sell ice cream—worth checking if the summer café is open(1).
