Tuusula Hiking Trails

The Seittelin Trail is about 4.1 km as a circular hiking route on the western shore of Lake Tuusula in Tuusula. For the Metsähallitus trail listing and map, start with the Luontoon.fi page for Seittelinreitti(1). The Uusimaa Recreation Area Association (Uuvi) manages Sarvikallio together with the municipality of Tuusula; their Sarvikallio area page describes the loop, orange route marking, clockwise recommended direction, winter maintenance on the access road and parking, fire rules, and services such as firewood at the fireplaces(2). Visit Tuusulanjärvi introduces the cliff view, the short gravel approach from the parking area, and how Seittelinreitti fits the wider lake shore(3). From Sarvikallion parkkipaikka the route climbs through mixed forest and old-growth patches toward Sarvikallion Laituri and the Sarvikallio shore, where a staircase leads down to the small pier. Around the midpoint you pass Sarvikallion Nuotiopaikka 2, Sarvikallion tulentekopaikka, and Fjällbonpuiston nuotiopaikka, with dry toilets including an accessible unit along the Sarvikallio section—handy for a longer stop before you swing south through Fjällbonpuisto. Toward the end of the loop, Anttilanrannan grillipaikka sits near the lake before the trail returns toward the parking area. In winter the same shore is linked to maintained ski connections such as Jäälatu Tuusula, Yhdyslatu Järvenpäähän, and Yhdyslatu Tuusulanjärven jääladulle where those tracks are groomed(2). Luontopolkumies Mika Markkanen’s Retkipaikka article notes a mostly gravel surface, clear signposts at junctions, a long boardwalk section over wet ground early on, a viewpoint toward Seittelinlahti before the climb, and roughly fifty minutes of walking without long breaks—also that joggers and cyclists share the path, so walkers should expect others passing by(4).

For closures, seasonal tips, and the list of recommended trailheads around Tuusula, start from the City of Tuusula’s dedicated Seitsemän veljeksen vaellusreitti page(1). Visit Tuusulanjärvi presents the same literary route as a roughly 90 km journey from Helsinki to Hyvinkää, following scenes from Finland’s first novel and sites linked to Aleksis Kivi(2). Tuusula lies in Uusimaa; this page describes the Tuusula segment only. The Tuusula section is about 21.4 km end to end on our map as one continuous path. It belongs to the wider Seven Brothers hiking trail network that runs from Helsinki’s National Theatre (Aleksis Kivi statue) through Vantaa and onward toward Nurmijärvi and Hyvinkää(2). On the Tuusula leg, the City of Tuusula describes the route entering from Vantaa across the Kulomäentie overpass, crossing Ruotsinkylän tutkimusmetsä toward Professorin pytinki, then continuing through Lahela toward Nahkela along the Tuusulanjoki valley and older village landscapes(1). In Ruotsinkylä the path can be stony; Lahela and Nahkela are easier going except for a rougher forest stretch at Ristikivi, which you can bypass using Ristikiventie(1). About 6 km along the route you pass Häklin uimaranta, where the municipality lists a swimming beach, dry toilet, and summer kiosk—useful for a long summer break(1). Lahelan Toukkapuiston lähiliikuntapaikka and nearby sports fields sit where the route threads between residential areas and green corridors. The research forest is a major landmark: Luonnonvarakeskus explains Ruotsinkylän tutkimusmetsä as a long-running field station landscape with varied forest types, rocky outcrops, and the three-kilometre Raition reitti education path with QR tasks—worth combining if you want a deeper look at forest research themes beside the main trail(3). The City of Tuusula also notes a separate three-kilometre loop in the forest with extra exercise content, and links Raition reitti materials for teachers(1). Free Citynomadi (Nomadi) mobile guidance with many hotspots along the full network is widely promoted for navigation and stories(1)(2). Independent listings such as kotimaassa.fi summarise the whole multi-municipality route and remind walkers that legs can be combined with cycling where surfaces allow(4). Where this segment meets other mapped trails, you can continue toward the longer Seitsemän veljeksen vaellusretti - Vantaan läntinen haara 12km toward Pitkäkoski and the Vantaa river valley, or pick up the Kuusijärvi - Tuusula retkeilyreitti 11km toward Kuusijärvi’s saunas and swimming—both useful links for multi-day planning along the same linked trail network.
