A cold wind moves through Kärkevagge as you step from the minibus and start up the rocky valley floor; boulders hunch like old watchmen, and the trail threads between them toward a pool that almost refuses to be contained.
Trollsjön (Rissajaure) sits at about 815 m above sea level at the valley’s head, fed by glacial melt and famed for water visibility reported to 36 m and a likely maximum depth near 70 m. The lake’s Sami name—Rissajaure—means the lake that glimmers like fire, and the landscape around it records ice, frost-shattered rock, and a human history of reindeer herding and mountain travel.
Geology here is immediate: a 5.5 km rocky gorge, massive rounded blocks, and an estimated 3,000 caves tucked between slabs where water and freeze-thaw sculpted the floor. Wildlife is visible from the path—reindeer browsing, bold mountain pipits, buzzards circling, and the occasional sea eagle sketching the skyline.
Expect a steady, moderate hike of several hours across uneven terrain with short climbs and loose scree. The lake is sterile and ice-cold—swimming isn’t warm or recommended. Guides typically drive you close in an air-conditioned vehicle, then lead the approach on foot in groups of up to eight.
Practical tips: bring layered insulation, a waterproof shell, sturdy hiking boots, and at least 2 liters of water. Start early for stable weather and clearer wildlife sightings; keep to trails and avoid disturbing fragile pools and tundra vegetation. The payoff is uncompromised mountain clarity and a raw Arctic valley that feels alive underfoot.
moderate.
6 hours.
Participants should have a moderate fitness level able to handle uneven terrain and a steady uphill approach for several hours.
The guided outing is typically a six-hour round trip including transport; hiking time on foot depends on group pace but plan several hours on trail.
While legally possible, the lake is glacial and extremely cold; guides generally advise against swimming to avoid hypothermia and to protect the fragile ecosystem.
Common sightings include reindeer, mountain pipits, grouse, hares, and various raptors; sea eagles are occasionally seen overhead.
Children with hiking experience and families used to uneven terrain can manage, but everyone should have good footwear and moderate fitness; the tour is not recommended for those with serious heart conditions.
The valley has long been part of Sámi reindeer herding territory; the Sami name Rissajaure reflects the lake’s shimmering quality in local tradition.
Trollsjön’s clarity depends on minimal disturbance—stay on trails, pack out waste, and avoid introducing foreign materials to the water.
