Ilhéou Pass

Highlight • Mountain Pass

This pass located at 2,256 meters above sea level is a pedestrian pass that connects the valleys of Ilhéou and Estaing.

It is a very vast, green passage offering spectacular views of the two valleys. In high season, herds (and patous, keep your distance) add a touch of authenticity to the picture.

Lake Ilhéou

Highlight • Other

The term Ilhéou comes from the Gascon to designate the gap. And judging from the location of the lake, its name is easily understood. Indeed, Lake Ilhéou is nestled in the hollow of a massif and surrounded by a string of peaks that tease the 3,000 meters.
