The area where the Marboré or Marmorés lake is located is considered one of the most beautiful natural landscapes in the entire Pyrenean mountain range. It is also a paradigmatic enclave in the history of Pyrenean mountaineering, which sought to conquer the great peaks.
At more than 2,500 m above sea level lies the plateau where the Cinca River rises, hidden by the peaks of the Monte Perdido massif to the south, the Astazu mountains to the west, and the border ridges to the north.
Meltwater from various snowfields feeds Lake Marboré. Located at an altitude of 2,590 m, its surface remains frozen until the end of June.
A young stream flows from the lake, which is joined by meltwater from the Monte Perdido and Marboré glaciers. When they reach the Balcón de Pineta, they plunge down the rocky escarpments of the great cirque, giving rise to the Cinca Waterfalls.
Next to the lake, and hidden in a small gap, is the Tucarroya Refuge, nestled in a rocky pass, or Forqueta de Tuca Roya, marking the border line between France and Spain.
