The dam is one of the highest in the Catalan Pyrenees, located at an elevation of approximately 1,780 meters above sea level.
The reservoir is fed primarily by glacial meltwater from the Maladeta massif and the surrounding high-mountain peaks.
The Cavallers reservoir plays a crucial role in the hydroelectric system of the Ribagorça valley.
The location serves as the starting point for some of the most demanding climbing routes in Catalonia, including those leading to the Besiberri massif.
The dam structure is a concrete gravity-type wall, designed to withstand the immense water pressure of the deep mountain basin.
Mirador Presa de Cavallers is a high-altitude observation point situated atop the Cavallers dam in the Aigüestortes i Estany de Sant Maurici National Park. The dam itself is a significant civil engineering feat, standing at approximately 80 meters tall and spanning the Noguera de Tor river valley. It creates the Cavallers reservoir, which serves as a major hydroelectric resource for the region. The lookout offers a panoramic perspective of the surrounding granite peaks of the Central Pyrenees, including Comaloforno and Punta Alta. Access to the viewpoint requires traveling the L-500 road through the Boí Valley. The area is a primary trailhead for mountain expeditions, including the Carros de Foc trekking route. The surrounding landscape is defined by glacial cirques and high-mountain ecosystems typical of the Catalan Pyrenees.

Bring polarized sunglasses to manage high-altitude sun glare reflecting off the reservoir water.
Carry trekking poles if you plan to continue on the trails beyond the dam, as the terrain is rocky and uneven.
Check the local weather forecast specifically for the Aigüestortes high mountain zone, as conditions can shift rapidly compared to the valley floor.
Do not attempt to hike to surrounding peaks without proper alpine gear and navigation skills, as this is a high-mountain environment with rapidly changing weather.
Access may be limited in winter and early spring due to high-altitude snow accumulation and potential avalanche risk on the access road.
Stick to marked trails to protect the fragile alpine vegetation and do not enter restricted areas of the hydroelectric facility.
