Pic de la Mainera, Mountain summit in Lleida, Spain.

Pic de la Mainera is a 2,909.3 m granite peak at the south-eastern edge of Aigüestortes i Estany de Sant Maurici National Park, where the municipal terms of La Torre de Cabdella, Espot and Sort meet. Its pyramidal horn, narrow vertical ridges and summit crest of jumbled granite blocks were shaped by Quaternary glaciers and frost shattering. The summit ridge runs north-west to south-east and is almost flat for about 200 m, with the highest point at its eastern end.

The summit marks the meeting point of three municipalities: La Torre de Cabdella in Pallars Jussà, and Espot and Sort (former Llessui term) in Pallars Sobirà. The nearby Cresta de l'Avió takes its name from a German aircraft that crashed there in 1943. The peak is listed among the FEEC's 100 cims.

The peak is one of the 100 cims de la FEEC, a list of 100 summits published by the Catalan Federation of Hiking Clubs, which brings hikers to it. Its name also marks the landscape: the Clot de la Mainera and its three tarns lie east of the summit, and the Coll south de la Mainera at 2,771 m is the usual pass on the climb from the Colomina refuge.

Visitors should bring proper alpine equipment and check weather conditions beforehand, as temperature and visibility can change rapidly. The climb demands physical fitness and mountain experience to navigate the terrain safely.

The summit ridge runs northwest to southeast and stays almost flat for about 200 metres, with the highest point at its eastern end above the south arete. The granite belongs to the Maladeta batholith, intruded between the Carboniferous and Permian over 300 million years ago.
