The ascent to the cross is car-friendly and has steps. The GR59 may have been rerouted in the meantime, but a detour here is definitely justified. The paths on Mt Poupet are well signposted and the summit cross is highly recommended.

This cascade flows into a bowl of very deep natural water (the gour). A local legend says that a cow fell in it and that it was never found! Very easily accessible place.
