Choranche cave (Coufin-Chevaline cave)
The cliffs looming around the village of Choranche are home to some wonderful caves, each very different from the other. The most famous is the Grotte de Coufin, a vast chamber 16m/50ft high and 70m/230ft wide, where thousands of dripping stalactites are reflected in the water of a lake. The tour continues through galleries illuminated to magical effect. The visit ends with a sound and light show in the cathedral chamber.
