La Roche Percée

Highlight • Natural Monument

The rock of this natural tunnel is limestone. It was erosion that made it possible to pierce the rock and thus created a window that was, to say the least, original.

Glandieu Waterfall Cave

Highlight • Cave

Cave which is larger than it seems at first glance, a lamp is mandatory to take full advantage of it and easily, for apprentice speleologists 😉

A must-see spot in the region, magnificent and impressive, but be careful of the incredible number of tourists in case of good weather during the day, choose to go there early in the morning!

Very nice site, and pretty waterfall. However, the very present tourist aspect spoils the show a bit, a security guard is even present to monitor the waterfall...I had never seen that before. Other equally beautiful and wilder waterfalls are to be discovered in Valromey
