The route from Spiez to Interlaken takes place on the rather shady side of Lake Thun, partially along the shore and through a variable Alpine countryside. The path goes from Spiez to Krattigen via Leissigen and Därligen to Interlaken. A highlight of the tour is the Spissibach-suspension bridge above Leissigen which was opened in 2012. It is 140m long and is located 60 meters above the forested gorge. This trail from Spiez to Interlaken is also a section of the Lake Thun circuit trail.
