After a pleasant 2-hour walk, we’ll enter the Dent network via its lowest entrance: the Guiers Mort and its thousand-year-old porch.

We’ll then take an unusual underground route that links 2 of the most beautiful existing routes in the network. The exit offers a magnificent panorama of the Grenoble valley and the mountains, from Mont Blanc to Oisans.

Then it’s time for a final effort to get back to our starting point and complete this route, which corresponds to stage 2 of the 7holes Challenge.
