Lac Sainte-Anne

Lac Sainte-Anne is an alpine lake in the Queyras range situated at roughly 2400 meters elevation, spanning about 9 hectares across the mountainside. A natural moraine formation acts as a dam holding back the water, which reaches depths of approximately 22 meters.

The lake formed through glacial processes during the ice age when moving ice shaped the mountain landscape and left deposits of rock. Later, military forces used elevated positions above it to observe movement through the alpine passes.

The chapel by the water holds local significance as a gathering place where nearby communities mark important dates together. This tradition shows how the lake remains central to the social life of the mountain villages.

The marked trail from Chaurionde gains elevation steadily over a climb lasting around two hours through alpine terrain. Sturdy hiking boots and layers are essential, as weather at this altitude can shift rapidly without warning.

The water shifts between shades of turquoise and deeper blues as daylight moves across the sky, creating a changing display throughout the day. This color play results from how light interacts with the glacial sediment suspended in the water.
