Lake Montagnon d'Iseye
Highlight • Lake
It goes up sharp, it goes down the same if you go around plan a good 7 hours
Just before arriving at the lake you have to take the path on the left so as not to go along the wall! After that there is a fairly steep part hard enough for people prone to vertigo.
For the rest, have fun!

Comments
The climb is steep up to the Col d'Iseye, but the slope then softens up to the lake. The grassy areas of Montagnon are home to many marmots.
