Thomas Roques Trail Details

The Thomas Rocques trail is a route that begins at the Tête Nord des Fours to reach the refuge Robert Blanc. It finally ends to the col de la Seigne (French-italian border). Of course you can walk this route in the other way.

The Thomas Rocques trail is more technical (screes, névés, cables and chains, rocky and steep parts, streams to cross,…) and so requires a good hiking experience. But it also is off the crowd you might see on the conventional TMB trail.

If you choose to hike this route, after the Tête Nord des Fours, you will walk through the col des Bouquetins, then the col de la Grande Écaille, and finally arrive to the refuge Robert Blanc. This first part is very wild and mineral, with small mountain lakes between the col des Bouquetins and the col de la Grande Écaille. From the col de la Grande Écaille you will be able to admire the amazing view on the glacier des Glaciers and the second part of the trail.

This trail should not be considered until early / mid-July with normal snowfall due to late snowfields. Contact us for recent information on the practicability of the trail!


The photos describe the route in the direction Tête Nord des Fours to the Col de la Seigne. It is quite possible to do the route in the opposite direction.
