The path to Lac de crop is somewhat steep at places, but it is well maintained and well marked. The view of the lake is truly rewarding. Highly recommended.

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.

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