The walking trail starts at the Låktatjåkka car park, about 120 km from Kiruna. Keep to the right at the start as you walk through the birch forest to cross the new railway bridge; follow the signposts. A slightly steeper climb then awaits, but soon the landscape opens up and you’ll be rewarded with a magnificent view of the mountain landscape. Stop for a breather by the large rock whilst you enjoy the view.
The walk now continues into Kärkevagge, a valley that truly lives up to its Sámi name, Geargevággi, meaning ‘Stone Valley’. Here, the trail winds its way through a truly fairy-tale landscape, filled with magnificent rock formations scattered throughout the valley. The large boulders are the result of the last ice age. You’ll pass through lush meadows teeming with mountain flowers, and right in the middle of the valley lies a large delta area. Along the way, you’ll come across small streams where you can top up your water bottle with cold, fresh mountain water.
At the far end of the valley lies Trollsjön, a very nutrient-poor mountain lake with low biological productivity and exceptionally clear water. This beautiful turquoise-green lake is fed by meltwater from the surrounding glaciers and is Sweden’s clearest, with a measured visibility depth of around 34 metres. Stop here for a while, eat the packed lunch you’ve brought with you and enjoy the surroundings before setting off on the walk back.
Trollsjön and Kärkevagge form part of the Låktatjåkka Natura 2000 site and are of high conservation value. When large numbers of people visit the same place, even small actions can have a significant impact.
