Within the bounds of this park, three regions of Spain meet at “el Tozal de los Tres Reyes”, a peak of 1356m, connecting Catalonia, Aragon and the Valencian Community.
The Els Ports Natural Park mountain range (Parque natural de Los Puertos) consists of calcareous rock dating back to the Mesozoic era and is characterized by its sheer outlines. It holds many peaks over 1000m, the highest of which is Mont Caro at 1447 metres. The rivers cut deep gorges creating an area of sharp contrasts.
Within the Els Ports protected area is “Les Fagedes dels Ports” which is a partial nature reserve. This smaller reserve further protects Beech tree woodlands and karstic cave formations.
