Mount Caro peak at 1441m. A demanding climb with a reward for the good views and the satisfaction of having made a good climb.

Unfortunately, due to the high temperatures in the morning, we had to turn back very early because it was far too strenuous for the dogs. Those who want to go on the tours here are advised not to go during the summer months, not even for the short tours 😉 We were here in June, unbearably hot, at half past nine... Otherwise fantastically beautiful and highly recommended, well signposted. We will come back one day, in autumn or spring.

This recreational area located in the shade of holm oaks and pines is a very important area for the inhabitants of Paüls. Not only is it the venue for their parties, but it is also the starting point for several hiking trails. It has an untreated water source.
