This hike goes around the Sierra De Bernia via historic steep hiking trails, such as the Camí de la Cova de la Serp, a historic bridle path. We also pass the ruins of the Fortress of Bernia. All around there are spectacular views in all directions.
The walk goes to the top of the Bernia from where you have a beautiful view of the surroundings. You also arrive at the ruins of the fortress of Bernia and go through an ancient tunnel where you have to crawl on all fours for about fifteen meters.
