The Tours d'Aï and Mayen are twin peaks visible from afar. The Tour d'AÏ is slightly higher than its neighbour, and also visited more frequently. It's a progressive climb which offers an aerial tour at the very end. Amazing views of Lac Léman, le Chablais, les Dents du Midi and the Mont Blanc massif from the summit.
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.
Passing through Tanay preserved site, and its lake, you'll climb to the summit offering a unique view point over Lac Léman and a panoramic view over the surrounding mountains.
A busy hiking trail with steep slopes but without any technical difficulty.
N.B. The calculated height difference is over estimated, it's actually closer to 1000 metres.
A not too busy hike up to a summit offering a vast panoramic view. A relatively challenging route with some aerial passages requesting a certain sense of itinerary at times. The beginning of the hikes passes through Tanay site and its lake.
An uphill hike taking you to the foot of the Eastern Peak (Cime de l'Est), eastern peninsular of "les Dents du Midi", with mind-blowing mountain view points and a panoramic view extending towards the Vaudois Alps. A challenging itinerary with a short aerial path through ridges.
