Where OpenStreetMap does not map the trail
Flötemarksön to Porsås: 14 km and 5 to 6 hours by West Sweden Trails, graded red (hard), and recommended only for walkers on a long walk who have to pass this way. The stage is not waymarked throughout. It is marked from Flötemarksön to the bridge at Holmen, about 4 km, and again from road 164 to Porsås. Between the Holmen bridge and road 164 you find your own way with map and compass, on paths and small roads, under the right of public access: road 164 is a clear boundary to the north, and walking south you keep Stora Kornsjön on your left until you meet the road to the Holmen bridge. Carry a map and compass and know how to use them. Our map has no path for this part: its dashed straight line of 4.3 km is not a route, so our 8.7 km and our time for this stage are far too low. Plan by the official 5 to 6 hours. It is about 22 km on the ground from Flötemarkens Vildmarkscamp to the next night, the Nornäs shelter. Tanum municipality, which looks after the stage, is working to make the trail continuous again.
Best season: All year. West Sweden Trails publishes no season: each time of year has its own character, it says, so plan for the weather and the hours of daylight. Some services are seasonal: the kiosk and toilet at Kåsjön open in summer only, and Friluftsfrämjandet lets the Modalen hut less in summer, when walkers use the shelter most. Before you go

Stage start
Trailhead
The stage end touches a public road, with a few parking places about 200 m north; no public transport. Flötemarkens Vildmarkscamp is just north. From here it is about 22 km on the ground to the next night, the Nornäs shelter.
Stage end
Trailhead
No stay at Porsås: the next night is the Nornäs shelter, at the end of stage 22. The Loviseholm bus stop, served from Ed in Dalsland, is about 2 km east.
Make it your trip
The trail's shelters (vindskydd) are open to all, first come; they cannot be booked. The hut on Vaktarekullen is always open and cannot be booked either. Friluftsfrämjandet lets Hällerstugan (booked online) and the Modalen hut (members, associations and schools, one night, booked ahead); Krokestugan is closed for overnight stays. Flötemarkens Vildmarkscamp takes guests by phone, for a fee; hotels, hostels, the lodge at Kynnefjäll and the campsites are booked with each of them. The right of public access lets you pitch a tent or two for a night away from houses and farmland, but nature reserves have their own rules: in two areas of the Svartedalen reserve tents are not allowed at all, and fires only at the places the county board marks.

Snow at the high point is estimated with a simple snowpack model from these temperatures and precipitation, not observed; steep islands and high summits can hold more snow than it shows. Daylight is for the 15th of each month. Hut, transport and park seasons are separate: check them for your dates.
Before you go
Arrange your stays, food and travel first, then check conditions again near departure.
Stage 21, Flötemarksön to Porsås, is not waymarked between the bridge at Holmen and road 164. You find your own way there with map and compass, on paths and small roads: road 164 is the boundary to the north, and walking south Stora Kornsjön is on your left. West Sweden Trails recommends the stage only for walkers who must pass this way; it gives 14 km and 5 to 6 hours. From Flötemarkens Vildmarkscamp to the Nornäs shelter, the next night, is about 22 km.
West Sweden Trails: stage 21From Kynnefjäll north, the trail crosses Bohuslän's largest wilderness: few roads, long stretches without houses, and buses that are very sparse, above all at weekends and in school holidays. Plan your nights in the shelters and huts and carry food for several days.
West Sweden Trails: stage 19West Sweden Trails posts the trail's status in its map planner. On 13 October 2026 it listed a collapsed bridge between Lilla and Stora Ramsjön on stage 5 (use the new one), logging at Romelanda on stage 7, forestry work on stage 8, and the bridge at Kaserna closed for rebuilding with a temporary footbridge. Read the notices before you set off.
West Sweden Trails: BohusledenStages 8 and 9 cross the Svartedalen nature reserve. In its areas 1 and 2 tents are not allowed at all, and fires only at the places the county board marks; use the shelters, such as those at Bottenstugan. Other reserves on the way have their own rules.
Länsstyrelsen Västra Götaland: SvartedalenFriluftsfrämjandet runs the huts on stages 14 and 15. Krokestugan is closed for overnight stays while its repairs are reviewed; Hällerstugan can be booked online; the Modalen hut is for members, associations and schools, one night at a time. The shelters beside them stay open.
Friluftsfrämjandet Uddevalla: KrokestuganOn stage 15 a raft on ropes crosses the Munkedalsälven in the Strömmarna reserve. When the water is low it cannot be used, Västkuststiftelsen has warned.
Västkuststiftelsen: the raft and the water levelGetting there
Travel around Flötemarksön to Porsås.
Google Maps journey searches, not confirmed services. A mountain endpoint may need a booked transfer or an additional walk.
Commuter trains stop at Anneberg station, handy for the start; the Älvsåkersgården bus stop is close by, and there is a large gravel car park at the trailhead.
Västtrafik: journey plannerRound Göteborg most stage ends have a stop: Gunnebo park (Stensjön), Welandersgatan with trams (Skatås), Åstebo (Kåsjön), the station at Jonsered and buses at Angereds kyrka. Further north buses are rare or absent: Grandalen and Anvik see very few, Hasteröd, Vassbovik, Bjursjön, Metsjö, Vaktarekullen and Flötemarksön have none. Munkedal has buses and trains, and Loviseholm, about 2 km from Porsås, is served from Ed.
Västtrafik: journey plannerThe trail ends in Strömstad, which has both trains and buses at its station.
West Sweden Trails: stage 27Take your trip with you
Prepare each stage while you still have a connection: in the forests and on Kynnefjäll the signal can be weak, and stage 21 needs a map of your own.
Keep your route and maps on your phone for places without a signal. For multi-day trips, prepare them in the installed TrailSplits app.
Saving a bookmark is not a map download. Storage can be cleared by your device; keep a backup map for remote trips.
Route & sources
West Sweden Trails (Västkuststiftelsen) publishes Bohusleden as 27 stages, about 350 km from Älvsåker, where it meets Hallandsleden, to Strömstad, with an official stage time for each, shown beside ours on every stage. The line here is the route on OpenStreetMap (the 27 stage relations of relation 280016, from the planet of 11 October 2026, without their side trips): 350.1 km, cut where the stage relations meet. Every stage is within about 1 km of the official length but one. Stage 21 is not mapped between the bridge at Holmen and Porsås, because it is not waymarked there: the map shows that part as a dashed straight line, 4.3 km, which is not a path. On the ground stage 21 is 14 km and 5 to 6 hours, walked by map and compass; plan by those figures, not ours. Our climb is measured on terrain heights, so short steep rises are smoothed out.
Official guidance and mapped-source comparison checked 13 October 2026. Map data is a route reference, not confirmation of today's path, weather or accommodation availability.
