As its name suggests, the Col des Lacs is surrounded by delightful small bodies of water, at an altitude of 2,234 meters. It is located at the foot of the Pointe de la Grande Journe.

It is a tricky short walk that takes longer than stated. We needed to scramble on parts of the ascent along a mountain ridge on the very thin trail, and the path was not always obvious on some of the ridge sections. The descent is also very steep towards the end, though thankfully this very steep section is fairly short. The lake was more of a quagmire when we walked it in early September. Not your usual crystal clear mountain lake and not particularly photogenic! Enjoyable, but for the length of the walk I would say it’s a harder intermediate.

In the spring, watch out for the snow, good walking shoes and in the summer, herd protection dogs.

Popular picnic point when the Piapolay chairlift is in operation. Otherwise quiet corner with beautiful view of Mt. Blanc.
