Lac des Sirènes is located in the town of Orcières in Champsaur, at an altitude of 2,396 meters.
The paths to get there are in good condition and the view magnificent.

Hiking

Easy access with the cable cars, but beware of the sudden change in altitude. Magnificent views follow, along well-marked but sometimes steep trails (not a particularly family-friendly hike, especially for older people). Well worth planning a day trip.
