생 피에르 당트르몽‬에서 가장 멋진 ‪20‬개의 천연기념물

The access is very well signposted, and you can do a lovely loop hike, starting from Saint-Même-le-Haut, or from Saint-Pierre-d'Entremont for the more adventurous. At the end of winter, the water level can be very high.

Magnificent view of the heart of the Chartreuse region, the plain of St. Laurent du Pont, and Mont Blanc in the background, seemingly within arm's reach. The access path via the ridge that connects to Outheran is very straightforward. The climb from St. Jean de Couz on the SW side is quite complicated. The path is barely visible and rather difficult to follow on a very steep face. The final section leads up a very steep couloir, through a slippery and unstable scree slope. Furthermore, the exposure to falling rocks is quite significant; extreme caution is required (helmet recommended). The final section consists of short climbing sections and very steep ascents in fairly exposed grassy terrain (fairly straightforward, but exposed).

The cross of the Aulp du seuil is located at 1825m above the cirque and marks the entrance to the high plateaus.

A stunning summit with views of Mont Blanc. The two climbs from the Col des Ayes are relatively steep, but steel cables are installed at the more dangerous sections. The climb north via the Trou du Glaz is a bit longer and a bit easier. The climb east is a bit steeper and more exposed. The view is good, though.

Magnificent! But be careful on the second part it is much more technical so hiking is ok, running less so :/

Great hike! Make sure you have good shoes with crampons because some slopes are a bit slippery. Magnificent view at the top.

on private property, with no-entry signs, especially at hunting time

Magnificent and relatively easy pass, with basic fitness. Offers a magnificent view of Mont Blanc. Be careful though, the Chaos and the Col are currently completely covered in snow. Being in a group, I did not attempt the ascent of the Col which, without equipment, can be particularly slippery and dangerous. Possibility of going back down via Prayet towards Saint Pierre en Chartreuse. Tested in November, however, no problems observed, very accessible.
