A natural spectacle in a class of their own are the 600m long Engstligen waterfalls. Under preservation since 1948, these are the second longest falls in Switzerland.
Embedded within an imposing backdrop of mountains, the deeply-blue Lake Thun lies on the northern periphery of the Alps, between the Bernese Oberland towns of Thun and Interlaken. Lake Thun is especially popular amongst sailors and windsurfers who appreciate the prevailing light breeze. Numerous swimming and shore areas invite visitors to cool off.
