Trübsee Loop is a nice trail accessible from town that passes by Untertrübsee and stunning Trübsee. Enjoy views of the Engelberg valley and the incredible colors of the lake. While it can be done in either direction, the trail between Engelberg and Berghotel is quite steep, so many people prefer to hike counterclockwise. There are several spots to stop for refreshments, and if you need to save your legs you can always take the gondola down from Trübsee back to town.
