Les Olles, in the municipality of Horta de Sant Joan, are a group of gorges of great depth, in which you can jump from the rock, as well as go up a small stretch of the river Canaletes. It is accessed from Horta de Sant Joan, by the route that passes at the foot of the convent of Sant Salvador, on the mountain of Santa Bàrbara, although it is not necessary to take the detour to the convent, but follow the signs to the Pots. There is a parking area next to the gorges and the rocks on the edges are quite flat to stretch the towel and sunbathe.

You can access this area of the Ports from Tortosa, by the C-12, or from Gandesa, by the Bot road. To get to Beseit from Arnes, take the A-231 towards Vall-de-roures. Terra Alta official website:
