The Tours d'Aï and Mayen are twin peaks visible from afar. The Tour de Mayen is slightly lower than its neighbour, not as busy and provides a more wilderness setting. The climb is progressive with two stages, the Chalets de Mayen and Segray Lake. Just beneath the summit, a very clear view of Lac Léman, les Diablerets, le Chablais, les dents du Midi and the Mont Blanc Massif.
