STIFINDER STI must have stumbled in the forest and was just able to hold on to the trees before he slipped into the lake. The path to the troll runs right along the water, with soft forest floor underfoot. Because there is a small stream at one point, wooden walkways have been built and covered with nets to prevent slipping.
From the car park, going to the right takes between 10 and 15 minutes, going to the left is probably about twice as long (or even longer).
In summer, I could also imagine swimming across the lake, the troll can be seen from the car park - so you can't miss it.
