Nestled in the Ossau valley, the lake of Castet offers a peaceful setting in the heart of the Pyrenean reliefs. It is an ideal stopover to take a break and enjoy the developed banks.

A good base for mountain bike tours through the Val d'Azun, as there are several parking areas. A pump track has also been built on the edge of the village.

This stretch of road is nice and offers a beautiful view. Be careful on the descent and be ready to brake, there are a lot of herds.

Wim van Est fell over the cliff here. They put a plaque on him, but there's no more room, so brake when you get here so the same thing doesn't happen to you! On July 17, 1951, during the Tour de France stage that covered the Col d'Aubisque, Dutch cyclist Wim van Est was wearing the yellow jersey, the highest distinction. He attacked on the descent, but slipped on a bend and fell into a 70-meter-deep ravine. Seeing that he was missing, his teammates and the team manager descended to search for him. It was then that a film crew spotted Van Est at the bottom of the ravine, and luckily, he was still alive. To rescue him, firefighters descended with a rope, but when they reached it, Wim van Est refused to be pulled up that way. "Give me another bike," he said, to the surprise of everyone present. Finally, they had to pull him up using a human chain. Fortunately, he only suffered a few bruises and scrapes, but he still had to withdraw from the Tour. The accident wasn't in vain, as, with the support of his sponsors, Van Est created the most famous watch advertisement in cycling history: "My heart stopped, but my Pontiac kept going."
