The Gorges du Verdon, whose source is near the Col d'Allos, one of the highest passes in France, extend over approximately 100 km. You can enjoy the view from above or walk down to the water's edge.
If the conditions are favorable, you can take good pictures of vultures, as they often pass very close to this rock when taking advantage of the thermals.
Be careful if you want to go back down the "real" path, there is a short 2m wall to climb to get down! Very dangerous if it has rained (it is better to take the T3 in the opposite direction!
