A 100km high mountain loop (around 8000m vert) starting and finishing outside the station in Villars-sur-Ollon, Vaud, Switzerland. The aim is to summit the three peaks that dominate the view from Villars: the Grand Muveran, The Dents du Morcles, and the Dents du Midi.

The summits are technical at times, so it is recommended to thoroughly check the routes up them before completing a round.

The Three Lakes Trail is named after the three lakes it formerly passed, one of which has since been drained due to a dam failure on Bean Blossom Lake.  It begins at Cherry Lake, which is very near the forest headquarters (directions to headquarters are below).  It is a 10-mile path which loops around back to the start.  It does have several large, long hills, somewhat tempered by switchbacks.  It also has some long stretches that are relatively flat and scenic, either along a high ridge top or following along a low stream or ravine.  Overnight backcounty camping is not allowed along this t
