Formed long ago after a rock fall, the Oeschinen Lake above Kandersteg is particulary worthy of being called a mountain lake. To the east and the south, the steep rock faces of the Blüemlisalp, Oeschinenhorn, Fründenhorn and Doldenhorn - all three-thousand-meter peaks - reach nearly all the way down to the lake surface.
The crystal cleft at Gerstenegg displays the fascinating world of crystals in their natural form. The cavern is situatet about 1.5 kilometers inside the Grimsel Massif. It was discovered in 1974 during construction work for a hydropower station and now constitutes one of the main attractions on the guided tour of the power station.
