We wanted to visit Gorropu, one of the deepest canyons of Europe, and decided to book Jebel Sardinia to take us there. We couldn’t have made a wiser choice: Sergio is a young, well-prepared, and multilingual very professional guide, with a solid preparation, who knows the territory like his backyard. Yes, it is also possible to go autonomously but (besides possibly getting lost) you will miss all the extra that you can get from a local: starting with the description of all the plants and trees, their function in the environment, their ancient use in medicine; the animals that populate the area, the myths, the rich history of that specific part of the island. Worth the extra in my opinion.
The trail is not that hard till about 2/3, but it is long, so you have to be used to walking. The last part of it (inside the canyon) is a bit tricky as you have to get over and around the big boulders that are stacked by the enormous pressure of the water during flood season. I think this is one of the “must-do” in Sardinia.
