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 Grimsel area forms the eastern border of the World Heritage Site. From the Grimsel Hospice and the Grimsel Pass Road, a hiking trail runs trough a dynamic mire landscape to the Aare glaciers north of the Grimsel Lake. These are the headwaters of the Aare River.
