This is a great rest area where the Pyrenees HRP / GR11 trail intersects with a drivable road. There are two bars available, though only one is open in the morning, the second seems more geared towards the dinner crowd. They serve both food and drinks, but be warned: *payment is cash only* as they do not accept cards (information accurate as of 2026). Because of the easy road access, it's a lively spot where hikers and cyclists often cross paths. Best of all, right next to the road, there is a highly convenient drinking water fountain and public restrooms. Definitely a useful waypoint on the trail!

Near the end of the stream section, the concrete blocks covering the stream are as of September 2025 completely missing, leaving you two options forward: 1) walk on a 20cm wide path right next to a big cliff, 2) walk inside of the stream bed, knee-deep in water. We decided to turn back because it did not seem safe for us. Caution recommended!
