This is the most spectacular feature in the reserve. From the outskirts of Sixt, there is a fine view of the pyramidal summit of Tenneverge. On the plan du Lac plateau, the road follows a broad curve and offers a spectacular panorama of the cirque and its waterfalls. In season, the reserve’s chalet has exhibitions on the local flora and fauna. The cirque comprises limestone escarpments on the wooded flanks of Tenneverge (2 985m), which dominates the Corne du Chamois.
