Cúber, Reservoir below Puig Major in Escorca, Mallorca, Spain

Cúber is a reservoir in the mountains of Escorca on Mallorca, created in 1972 behind a dam. The water sits among steep rocky slopes and forested areas, with the surrounding land covering more than 360 hectares.

Cúber was created at the end of the 1960s and beginning of the 1970s at an altitude of 750 metres, with a capacity of 4.64 million cubic metres. It was built to supply drinking water to the municipality of Palma, together with the nearby Gorg Blau reservoir, which holds 7.36 million cubic metres. The name comes from the nearby Cúber estate, which also gives its name to the Morro de Cúber peak above the dam.

The name Cúber comes from the nearby Cúber estate, which also gives its name to the Morro de Cúber peak above the reservoir. The reservoir and the neighbouring Gorg Blau supply drinking water to Palma and its metropolitan area through the Torrent de Almadrà.

A marked circular walk of about 4 kilometers goes around the reservoir and takes about an hour. The paths are not suitable for wheelchairs or strollers due to stairs and uneven ground, but the trails are well maintained and easy to follow.

The reservoir holds 4.64 million m³, less than the neighbouring Gorg Blau with 7.36 million m³. Together the two reservoirs would cover Palma's water demand for only about 58 summer days. The name comes from the nearby Cúber estate, which also gave its name to the Morro de Cúber peak above the water.
