A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

Don't trust the no trespassing sign. Private property! Danger of death prohibited! We almost missed it because of those two signs! You have to be careful, yes, like everywhere! But to put danger of death 🙄! Plus, there's a lifeline where there would be danger! But honestly, we didn't see any danger! Done with an 8-year-old, no problem!

You can stop at Michel Mauret, an excellent pastry shop where you can enjoy a meringue to die for or an excellent apple, pear or prune croustade!! Note that the croustades are for at least 4 people, to share! Or for very very big appetites ;-) Moreover, this timeless place is magnificent and soothing! Just be careful: no credit cards accepted, be prepared!
