Montmalús, Mountain summit in Encamp, Andorra.

Montmalús is a summit in the eastern Pyrenees located near Encamp at 2781 meters elevation. The peak sits within the Pessons range and offers views across the surrounding mountain landscape from its ridge.

The name Montmalús is documented in 12th- and 13th-century forms such as Momoluze, Mumuluz and Mamulucz, which the philologist Joan Coromines linked to a pre-Roman Basque-like root alu-tze, meaning source, for the streams rising near the peak. He also compared the Mam- element to Latin mamma, a breast, describing the conical relief. The summit lies on the primary axial chain of the Pyrenees, built of granite of the Mont-Louis-Andorra batholith, which covers 600 km2 and reaches into Spain.

The name comes from the hamlet of Montmalús in Ger, Cerdanya, visible from the peak and vice versa. Joan Coromines linked the medieval forms Momoluze and Mumuluz to a possible pre-Roman root alu-tze, meaning source, for the streams rising near the peak. The summit overlooks the Estany de Montmalús and its refuge.

The trail to the summit measures about 7.8 kilometers with elevation gain of roughly 654 meters. Most hikers need about five hours for the round trip, depending on fitness level and weather conditions.

Montmalús is one of the five main peaks forming the Pessons cirque, together with the pic des Pessons (2,857 m), the pic Alt del Cubil (2,833 m), the pic Baix del Cubil (2,705 m) and the pic de l'Àliga (2,820 m). Its topographic prominence is 76 m.
