Panoramic view, over the Savoyard pre-Alps, the lake, the Dent du Chat, le Revard, Croix du Nivollet and in clear weather even as far as Mont Blanc! The route does not require any particular physical condition but requires vigilance to place your feet well in order to avoid rocks and roots on the path.
