Calanque of the Salt Waters

But it's done well and it's very pleasant!

The park is only open on Wednesdays and Sundays. The remains of this industrial site are interesting and well explained through posters.

Description of the hike: follow the path from the parking lot to reach the source. The start is under a large metal portico bearing the inscription "Chemin de l'Infernet". The walk is part of the GR13. It is marked with red and yellow lines. A very simple little walk, no equipment necessary. Very few places for parking!
