El Tossal dels Tres Reis is a 1356 metre high summit found on the boundary between the Valencian Region, Aragon and Catalonia, which used to make up the Crown of Aragón. Vall-de-roures is to the north, the town of La Sénia to the east and La Pobla de Benifassà to the south. It is a few kilometres from Fredes, which can be accessed by car along a forest road. It can also be accessed via a path, which takes you up the summit, from which you can enjoy a privileged view of Tinença.
