these are splendid glacial lakes located at about 2,320 meters above sea level, a bit secluded and hidden, in a "comba" on the path to the Fenêtre Durand.

The tiny village of By is nestled in the splendid namesake basin surrounded by imposing peaks of surprising beauty, arranged in a worthy crown: the Grand Combin, Mont Velan, Mont Gelè and the rocky chain of the Morion, nicknamed "the ugliest mountains in the Aosta Valley". Departure and arrival: Col Champillon. From the pass, take the dirt road continuing from the asphalt, ignoring any deviations, and in just under 10 km you will find yourself in this magnificent basin dominated by a reservoir at 1988 m altitude, among horses and cows grazing freely; places like these are absolutely to be safeguarded and protected!

The des Thoules lakes occupy a shelf at about 2,320 meters in the Comba des Eaux Blanches, the valley that rises from the By basin towards the Fenêtre Durand, the ancient border pass with Swiss Valais. They are two modest-sized, intensely blue basins, nestled next to each other on an alpine meadow plateau.

In June I had difficulty bypassing the avalanche debris that was covering the dirt road.

A very beautiful Alpine-style tour, steep in sections but cyclable. On the way down, you cross several streams that can become impassable after heavy rains or spring thaws. Be aware that there are two exposed sections that require caution; fixed ropes facilitate the crossing. Be aware that one section is closed (barriers have been knocked down) due to a collapsed wooden walkway. The section is manageable but carries a high risk of falling (you have to carry your bike over a 15 cm thick and 1.5 m long beam!) Before this, a very narrow section in a rocky crevice is almost impossible to cycle; the handlebars barely fit. One solution is to bring suitable wrenches to fold the handlebars parallel to the frame. Be aware that these sections require absolute mastery, with exposed and dangerous sections. October 17, 2025 The ride is beautiful and very scenic.

The Ru de By is a charming stream well known in the area because of the path that runs alongside it. Follow the water, you're sure to be on the right path.
