Magnificent trekking, also worth doing with the family, even if you are a little trained. We went with two girls aged 6 and 7. Stunning landscapes and acceptable altitude difference.

The ascent beyond the Refuge of Nice is characterized initially by the Lake of Fous and later by several small glacial lakes. After the Baisse du Basto, you pass another body of water before seeing the imposing Lac du Basto for the first time. The Vallée des Merveilles is also characterized by numerous lakes, although these are mainly reservoirs around the Refuge des Merveilles.

As lovely as this lake is, it’s not busy with people even during the summer, so a great place to stop for a quite lunch if you have been taking it easy from refuge des Merveilles

Nestled on a rocky promontory overlooking Lac de la Fous, Nice's bucolic refuge is immersed in a spectacular setting. If you pay attention you can observe ibexes and chamois in the surroundings of the chalet. More information on the refuge here: www.refugedenice.ffcam.fr.

Nestled at 2,548 meters above sea level, the Pas du Mont Colomb is an impressive passage that is between two rocks. It offers beautiful views on each of its slopes at the end of an approach on very mineral terrain.
