Nurmijärvi Hiking Trails

Kiljavannummen ulkoilureitit—the Kiljavannummi outdoor trails—is about 26.5 km as one point-to-point line across the Kiljavannummi and Sääksjärvi area in Nurmijärvi, Uusimaa. It is not a loop. The City of Nurmijärvi describes the wider Kiljavannummi network as roughly 35 km of municipally maintained summer trails and winter ski tracks on easy-going terrain, with marked routes continuing through Petkelsuo toward Hyvinkää; the area lies on Lohjanharju and is described as very snow-sure in winter(1). For current maps, grooming, and any closures, their Kiljavannummi ja Sääksi page is the right place to start(1). On this line you pass from the Kiljava institution and Sääksjärvi shore toward open pine heath and the Herusten sports area, finishing at Rajamäki’s large sports cluster. Near the start, Sääksjärven uimaranta Nurmijärvi is a summer swimming beach with outdoor fitness equipment and beach volleyball courts beside the path. Kiljavan leirikeskuksen talviuintipaikka offers winter swimming for those combining a walk with a cold dip. In Herusten, frisbee golf and an ice rink sit next to the trail. At Rajamäki, Rajamäen uimahalli and Rajamäen liikuntapuisto group many outdoor facilities—running track, disc golf, ball fields, athletics, skatepark, and more—so the end of the route is an easy jump to services and shorter exercise loops. The same corridor is used in winter by Kiljavannummen ladut, the parallel ski trail of similar length. The Seitsemän veljeksen vaellusreitti Nurmijarvi and Seitsemän veljeksen vaellusreitti Hyvinkaa hiking routes meet this line around Herusten; the dedicated Seitsemän veljeksen reitti page lists the Nurmijärvi section at about 33 km and medium difficulty, with a free NOMADI mobile app and downloadable PDF maps including Rajamäki–Herunen(2). Rajamäen liikuntapuiston kuntorata is a short signed running loop at the Rajamäki sports park if you want an extra lap after the main trail. Independent walkers add useful ground-level detail. A 1000 kilometriä day hike on the Märkiön route—one of the marked loops on Kiljavannummi—notes well-posted recreation routes, parking at Kehityksen maja, Matkunsuo mire reserve, views from the esker toward Märkiön lampi, a grill and laavu near Märkiön leirikeskus, and noise from the Hanko–Hyvinkää road where the path runs close to traffic(3). Jalkaisin’s Finland-on-foot journal describes using the municipal trail map at Kiljava and following Kiljavannummen ulkoilureitistö paths toward an overnight camp, noting plenty of routes but not always dense signposting—worth pairing with a map app for navigation(4). Nurmijärvi lies in southern Uusimaa north of Helsinki. The names Nurmijärvi and Uusimaa appear here so city and region pages link cleanly.

Isosuo Nature Trail is about a 3 km marked circuit on duckboards and short forest links around Klaukkalan Isosuo raised bog in Nurmijärvi, beside the developing Vanha-Klaukka neighbourhood in Uusimaa. Uuvi(1) lists parking, marker colours, on-leash dog rules, the short accessible spur, and the blue and yellow loop lengths for this site. The City of Nurmijärvi(2) built the boardwalk network to keep visitors on hardened tread and lighten pressure on the protected Natura mire. Official copy on both pages describes two colour-coded loops you can walk as one outing: blue on the northern ring and yellow on the southern ring, joined by a short connector(1)(2). The landscape is mostly level mire with interpretation boards on bog plants, peatland types, and narrow strips of forest; dry benches sit at rest points rather than campfire rings, because open fires are not allowed on the protected mire(1)(3). Start from the Klaukkala ice hall side of the sports block: a gravel approach leads to the forest edge where the loops split left and right(2). You can leave cars near Klaukkalan jäähalli and the dedicated Isosuon luontopolku parkkipaikka—both sit in the same convenient cluster off Lepsämäntie(1). Retkipaikka(3) walked both rings clockwise in one go, noted blue diamond markers once the duckboards begin a few hundred metres in, and allowed around 50 minutes for the roughly three-kilometre outing with plenty of other day hikers on a sunny Sunday. Staying on the built route protects the Natura mire after past extraction work and machine access during construction(2)(3). Waterproof shoes are still a sensible backup after wet weather, but the duckboards kept the going easy when Retkipaikka(3) visited.

The Nukarinkoski nature trail is about 2.1 km along the largest rapids on the Vantaa river system in the Nukari village area of Nurmijärvi, Uusimaa. The rapids stretch roughly 1,300 m with about 25 m of drop, and a footbridge crosses mid-rapids at the historic dam sometimes called Nukarin tammi, a setting Finnish readers know from literary history(2). The City of Nurmijärvi publishes the practical rules for the area, including fire and dog policies and links to further outdoor guidance(1). The Uudenmaan virkistysalueyhdistys visitor pages for the same site add route context, season tips, and accessibility limitations(2). Along the walk you quickly pass Nukarin koulun liikuntasali and Nukarin koulun lähiliikuntapaikka, then reach Nukarinkoski Laavu above the water on duckboards, a natural coffee stop before you swing toward Nukarinkoski parkkipaikka and Nukarin hiekkakenttä, where many people base outings. About 1 km in, Nukarinkoski Outdoor Grill 2 sits close to the path for a marked cookfire, and farther along you brush the edge of Talli Glaesihrossin ovaalirata and Talli Glaesihrossin ratsastuskenttä before closing on the main Nukarinkoski viewpoint and Nukarinkoski Outdoor Grill near the end. Expect forest paths, short climbs, and popular weekend use. Luontopolkumies summarises boardwalk spurs, sports-field parking at Nukarintie 32, and the residential links that are easier to follow with a map on Retkipaikka(3). Reissukuume describes icy steps, busy lots, and how two separate parking areas work in practice on a winter weekend(4). Some descriptions round the full circuit to about 2.8 km when detours and zig-zags are included(3), while the trail length here follows the continuous riverside line at about 2.1 km. Terrain stays mostly under forest canopy with openings at the rapids. The area is a familiar family outing and fishing destination; bring your own firewood because supply is not maintained, and observe wildfire warnings(1)(2).

Myllykoski nature trail is about 1.5 km on one walking line beside the Vantaa River rapids in Nurmijärvi, Uusimaa. The City of Nurmijärvi maintains nuotiopaikat, firewood logistics, and practical visitor notes for the Myllykoski outdoor area on Nurmijarvi.fi(1). Heavier ecology, history of the rapids and hydropower, the Koskikara and Puulajipolku-themed loops, QR stops, and fly-fishing rules are described in depth by Keski-Uudenmaan ympäristökeskus(2). Suomen Luonto’s winter trip note for Nurmijärvi’s rapids spells out how the two about-1.5 km themed circuits relate to the same Siippoontie parking, where to find Pikkukosken laavu, and why duckboards and stairs deserve extra care in ice and wet weather(3). For a relaxed photo walk through the same river scenery, Reissukuume’s day-hike write-up pairs well with the official safety hints(4). Along the route you soon pass Nurmijärvi grillipaikka, then Myllykoski, Vantaanjoki with its pools and bridges, and Myllykoski Tulipaikka for a campfire stop. About 0.8 km into the walk you reach Pikkukosken laavu, a natural lunch shelter with firewood managed by the municipality—read more on our page for that laavu. Toward the end you arrive at Myllykoski parkkipaikka, the main Siippoontie-side parking visitors use for these trails. The east-bank duckboards form part of the much longer Seitsemän veljeksen vaellusreitti Nurmijarvi hiking corridor that continues north toward Hyvinkää and south toward the capital region when you want more kilometres.

The Seven Brothers Trail (Nurmijärvi section) is about 35.7 km of the classic Seitsemän veljeksen vaellusreitti, the long-distance path inspired by Aleksis Kivi’s novel that runs roughly 90 km from the Aleksis Kivi statue in Helsinki through Helsinki Central Park, Vantaa, Tuusula, and Nurmijärvi to Hyvinkää. Nurmijärvi lies in Uusimaa. For difficulty notes, PDF maps such as Rajamäki–Herunen and Kirkonkylä, and the free NOMADI app with maps and place-based stories, start with the City of Nurmijärvi’s Seitsemän veljeksen reitti page(1). The municipality describes the Nurmijärvi leg as moderately demanding because the tread is uneven, and as roughly 33 km in their overview—slightly shorter than the continuous GPX segment on our map at about 35.7 km, which is normal when different start–end cuts are used(1). The route is meant for hiking and trekking and partly for skiing and cycling on shared paths(1). From the Herusten area the same waymarked system links into Kiljavannummen ulkoilureitit and continues toward Seven Brothers Trail (Hyvinkää section); for the Hyvinkää continuation and Kytäjä–Usmi, use the City of Hyvinkää’s Seven Brothers pages and Luontoon.fi together(2)(5). Along this section you pass the fringe of Rajamäen liikuntapuisto, then open countryside and river scenery toward Nurmijärvi centre. At Myllykoski on the Vantaanjoki the trail passes Myllykoski, Vantaanjoki, Nurmijärvi grillipaikka, Myllykoski Tulipaikka, and Myllykoski parkkipaikka, with Pikkukosken laavu a little farther along for a lean-to stop. Uudenmaan virkistysalueyhdistys describes the Myllykoski rapid as about 400 m long with an 11 m drop, three footbridges, flood meadows, and wooded slopes; Koskikaran luontopolku is a short nature loop there, and open fires are allowed only at marked fireplaces(4). Firewood to the barbecue area is delivered seasonally; in mid-winter icy roads can limit restocking(4). The City of Hyvinkää documents the wider Seven Brothers Trail as marked with blue-painted wooden posts and signposts at junctions, with slippery rocks and duckboards when wet—sturdy boots are recommended—and spring flood detours around the Paalijoki bridge when needed(2). Tuusula recounts in its official Seitsemän veljeksen material how the capital-region hike was conceived in 1964; the full chronology is in the history section(3).
