Lahokallio nature trail is about 1.8 km of easy–moderate walking on forested Lake Lohjanjärvi shoreline near Ojamo, a few minutes from downtown Lohja. Lohjan kaupunki describes Lahokallio’s steep rocky shores toward the lake as unusual locally and the view from the rock tops toward Lohjanjärvi’s open Isoselkä bay as a main reason people visit(1). The same authority lists the trail on Luontoon.fi for national outdoor browsing purposes(2). Uusimaa offers many short lakeshore walks; this one stays very close to Lohja services. Along the route you move through lush deciduous forest, riverside herb-rich woodland and wet hollows typical of the shore zone, with spots where glaciation shows in the bedrock. The official page marks the trail with small yellow paint blazes, ties in twelve themed information stops with a PDF guide, and warns of damp, muddy shore sections in spring and autumn and slippery roots and rock after rain; waterproof boots are a good idea then, and the trail is not barrier-free because of rocky and uneven stretches(1). Retkipaikka field notes praise duckboard sections near the shore, a sand beach and swim ladder in a sheltered bay, benches on open rock at the northern tip with wide lake views, and picnic clearings—good reward for a short outing(3). RETKI JA REISSU describes a relaxed summer visit with a dog and long swimming stops from the same parking pattern(4). Clockwise from the Lahokallionkatu–Everstinkatu corner reaches the main map boards sooner, which helps where on-ground signs feel sparse(3). About 1.8 km from the start, the line passes the Ojamo school cluster: Ojamon koulun liikuntahalli, Ojamon tekonurmi and Ojamon koulun luistelukenttä on Kartanonkuja—handy landmarks if you park at the sports hall or finish near the school grounds. Across the water, Liessaari with its footbridge hosts another of Lohja’s nature trails if you want to combine visits another day(3).

For route maps and current notices from the manager, start from the Liessaaren luontopolku page on the City of Lohja website(1). Liessaari Nature and Wellbeing Trail is about 4.7 km as a circular hiking route on Liessaari, an island in Lake Lohjanjärvi just southwest of Lohja in Uusimaa. Suomen Luonto’s day-trip story gives a readable introduction to the wellbeing stations and quarry history(2). A footbridge links the island to the mainland; the swimming beach and Liessaaren rantauimala sit right beside the bridge, and Liessaari Beach a little farther along the shore. Early along the circuit you pass the Ollisaari shore area, where Ollisaaren tulipaikka, Ollisaari camping site, Ollisaari Sauna, Ollisaari Cooking Shelter, and Ollisaaren eteläkärjen tulipaikka make a natural break before or after the main loop, and Ollisaari - Melojille soveltuva rantautumispoukama offers a kayak-friendly landing if you arrive by boat. About halfway around, the western side of the island gathers Liessaaren Laavu and Liessaaren Uusi Laavu with campfire space—good lunch stops before you climb toward the old red microcline granite quarries; Suomen Luonto describes the fenced quarry bowls as monuments to Lohja’s industrial stone industry from the mid-1800s into the 1940s, with stone shipped as far as Porvoo and Saint Petersburg(2). Interpretation boards along the path explain geology, vegetation, and glaciation; the same article highlights a themed “Luonnontie” wellbeing section with short stations that invite you to slow down among spruce and sounds of the lake(2). Retkipaikka’s write-up from Antti Huttunen is a good companion read for the western laavu and quarry rim after rain(3). Near the end of the loop, Haikarin ulkokuntosali and Haikarin avantouintipaikka ja yleinen sauna sit close to the mainland link for a strength circuit or sauna and winter swimming, depending on the season. Further terrain colour—eastern shore esker walking, spring flowers in herb-rich forest, and views over Lohjanjärvi from the higher west-side rock—appears in the magazine piece(2). Retki ja Reissu notes sharp relief on the island, strong scenery toward the west, and popularity in summer(4). If you plan a paddling leg, the Lohjanjärvi Kayak Island Tour is the long-distance water circuit that shares several island landings with hikers. In icy winters, the nearby Matkaluistelurata Aurlahti-Hevossaari tour-skating track is a separate activity on the lake near Aurlahti.

The Paavola nature trail is about 0.8 km and makes a short marked loop through Paavolan tammikko on Lohjansaari in Lohja, Uusimaa. The woods hold one of southern Finland’s showcase deciduous groves: oak, small-leaved lime, hazel patches, rocky oak stands, and small meadow clearings threaded by a short brook, all protected as Paavolan tammikko nature reserve. Close to the former village school and Pietiläntie, the same climb brings you past Lohjansaaren ulkokuntosali, Lohjansaaren luistelukenttä, and Lohjansaaren hiekkakenttä—easy landmarks if you arrive by car for the schoolyard parking. The City of Lohja publishes printable maps, an ArcGIS web map, reserve background, and practical notes on its Paavolan luontopolku page(1). Lohjan Saaristo offers the trail information texts as a downloadable PDF and suggests allowing at least half an hour so you can read each sign and revisit in different seasons(2). The path reaches a rocky viewpoint above the canopy and continues to Paavolan tammi, an ancient English oak designated a natural monument and often named among Finland’s most famous single trees. The marked loop includes fifteen nature-trail interpretation stops altogether(1). Retkipaikka’s walk-through by Luontopolkumies Mika Markkanen describes duckboards encircling the oak’s root zone, a picnic table for a snack stop, dryish footing in ordinary trainers on an easy grade, and a polite reminder to stay on the path because the old school property next door is private(3). The route is not maintained in winter; compacted snow and ice can make rock steps and duckboards slippery(2).

The Torhola Cave Trail is about 0.4 km one way from Torholan luola pysäköintialue on the Karkalinniemi peninsula in Lohja, Uusimaa, toward Finland’s best-known walk-in karst cave at Torholan luola. For reserve rules and the Metsähallitus route listing, start with Luontoon.fi(1); for trailhead details, seasonal notes on the longer marked circuit, and conservation reminders in the Torholan luolan luonnonsuojelualue, rely on the City of Lohja(2). Park at Torholan luola pysäköintialue and follow the marked path to the cave mouth, where an information board explains how the cavern formed and what to expect underground. Retkipaikka walks through the main chambers by name—Torholan eteinen, Torholan sali, and the lower Torholan kellari that stays cool year-round—and notes how many visitors turn back after the airy entrance rooms while others continue with a headlamp through short drops and crawl sections(3). The City of Lohja stresses that entering the cave is always at your own risk and recommends a flashlight, care on wet rock in spring and autumn, and using the right-hand side of the cave for the metre-and-a-half step down into the main hall area(2). Beyond the cave, the city’s marked nature route continues down a railed slope to a sandy Lake Lohja beach backed by old pine and rare elm, then loops through streamside herbs and veteran small-leaved limes before rejoining the parking track on a route they describe as roughly one kilometre overall(2). That wider loop shares the same green-blazed network but is longer than the 0.4 km segment mapped here. Collecting plants, disturbing wildlife, or damaging soils is prohibited in the reserve, open fires are not allowed, and on windy days you should watch for trees the city lists as vulnerable to blowdown along the trail(2). Retkipaikka also points to a smaller second cave nearby for enthusiasts who explore the rocky fringe(3).

Karkali Nature Trail is about 5.3 km as one marked path through Karkali Strict Nature Reserve, a hazel-rich woodland peninsula in Lake Lohja near Sammatti in Lohja, Uusimaa. Metsähallitus manages the reserve; for closures, access rules, and the published trail description, start from Luontoon.fi for the Karkali nature trail (1). The City of Lohja explains how the roughly six-kilometre marked network leaves the nature-reserve parking area and includes the Hanski-Haki nature trail with ten topic boards on local trees, meadow flowers, big aspens, and birds—easy ground that usually takes about one to two hours for that shorter loop (2). Movement is on foot or skis only on marked paths, rest spots, and the swimming beach; stepping off-route, landing anywhere except the marked landing, or overnighting without a written Metsähallitus permit is not allowed (2). Along the route, about 3.1 km from the start you reach Karkalin rantautumispaikka, the designated canoe and boat landing beside Lake Lohja. Later in the outing you pass Karkalin pysäköintialue, where many drivers begin or end their visit; Karkali uusi kuivakäymälä sits close to that parking strip. Muurahaisten poluilla notes rooty tread, short duckboard stretches, and picnic tables on the shorter circuit, but calls the paths unsuitable for prams (4). Retkipaikka describes a winter walk on the six-kilometre circuit from the same parking area, with cone-shaped route markers on the nature-trail section and yellow paint on the longer loop, and highlights small springs, shoreline rock, and wind-voices in tall forest by the lake (3). MATKALLA LUONNOSSA reminds that picking berries or mushrooms in the reserve is not allowed, unlike ordinary Everyman’s Rights forests (5). Many people pair the peninsula with a separate look at Torholan luola, a long karst cave on Karkalinniemi reached by its own short trail from Karkalintie—plan that as an add-on because it is not part of this trail.

For rules on fires, dogs, camping, current closures, and which buildings are in use, the Ollisaari destination page from UUVI is the clearest place to plan a visit(1). The City of Lohja has also posted news about seasonal water connections from Aurlahti toward the island—worth checking for dates, prices, and special event transport before you travel(2). Patikkamuistio’s Lohjanjärvi island-hopping write-up captures how kayakers tie Ollisaari into a longer laavu tour past Kaurassaari and toward Hevossaari and Liessaari(3). Lohja sits on Lake Lohjanjärvi in Uusimaa. The trail is about 0.3 km as a compact marked loop on six-hectare Ollisaari, a rocky west shore and more sheltered east side with views across the water. Stay on the marked path, especially in the sensitive northern groves UUVI highlights. Along the loop you pass Ollisaaren tulipaikka and, toward the south tip, Ollisaaren eteläkärjen tulipaikka—both good pause points if campfire rules allow. Ollisaari Laituri on the east side is the practical landing; a marked cove suits kayaks at Ollisaari - Melojille soveltuva rantautumispoukama. Ollisaari Cooking Shelter and Ollisaari camping site support longer stops; dry toilets are sited for the island. Read more on our pages for Ollisaari Sauna when you need rental nuance, while UUVI notes some main-building and sauna facilities have been temporarily out of service—confirm on their page before counting on indoor services. From the same waters, Matkaluistelurata Aurlahti-Hevossaari is the maintained winter tour-skating line that calls at Ollisaari, and Lohjanjärvi Kayak Island Tour strings together beaches and shelters around the lake. Across toward Liessaari, Liessaaren luonto ja hyvinvointipolku is an easy companion hike for a second island. Hevossaaren Laavu sits a short paddle away for those building a wider day on the lake.

Paloniemi nature and culture trail is an about 0.9 km loop on the former Paloniemi manor lands a short drive northwest of Lohja centre in Uusimaa. The trail threads mixed shore and grove forest off Lake Lohja, with Paloniemi Beach, Paloniemen uimapaikka, and Paloniementien hiekkakenttä all within easy reach for a swim, a towel break, or ball games after your walk. For printable maps, story-map tours, and how the trail is maintained, start with the Paloniemi trail materials published by City of Lohja(1). Visit Lohja summarizes the four-hectare manor-grounds setting and interpretation boards in English(2). Luontopolkumies Mika Markkanen’s Retkipaikka report adds practical detail on yellow tree markings, ridge footing, the halfway bench, optional side paths toward the historic pavilion, and how quiet the loop can feel on a summer morning(3). If you combine hiking with paddling, the Lohjanjärvi Kayak Island Tour passes the same Paloniemi Beach and Paloniemen uimapaikka that sit near this trail—check our pages for those stops when you plan a longer lake day.

Pähkinäniemi nature trail is about 1.8 km as a loop on the Pähkinäniemi peninsula south of central Lohja near Virkkala in Uusimaa. The City of Lohja publishes a trail PDF, printable map, and Story Map on its Pähkinäniemi nature trail page, including the texts for sixteen numbered nature posts marked in the terrain with numbered wooden stakes(1). The peninsula has long been a popular recreation shore: the name comes from widespread hazel thickets, and the lime-rich soil together with lime dust from the Virkkala cement works has created habitat for rare mosses and fungi described along the trail(1). About half a kilometre along the shore side you reach the tip benches and Lake Lohja views, and about 0.8 km into the circuit you pass Pähkinäniemen uimaranta for a swim in summer. Near the trailhead area, Järnefeltin ulkokuntosali offers outdoor gym equipment a short walk from the path. Retkipaikka’s walk-through by Luontopolkumies Mika Markkanen notes a mix of narrow forest path and wider shared outdoor corridors, junction signs and posts, benches at viewpoints, and the western cove beach beyond the main swimming beach(2). Retki ja Reissu calls the peninsula a cosy green pocket and highlights the leafy grove character, horse chestnut and other broadleaf trees, a handful of interpretation boards, and several benches along a little-over-one-kilometre walk(3).
