Montsec is a calcareous mountain range more than 40 kilometres long, covering an area of 18,696 hectares divided between Aragon and Catalonia. The Catalan side covers various municipalities in the counties of Pallars Jussà and La Noguera.
The thrust and erosive power of the Noguera Pallaresa and Noguera Ribagorçana rivers have carved out and shaped the spectacular gorges of Mont-Rebei and Terradets, at the same time dividing the mountain range into three sections: running from west to east, Montsec d'Estall (in Aragon), Montsec d'Ares and Montsec de Rúbies (in Catalonia).
