[2][3] Peñas del Chache is a rocky mountain located in the Famara massif.

Peñas del Chache is a basaltic intrusive formation dating from the Miocene period, and is part of the Famara volcanic edifice, one of the oldest massifs on the island.

[4][5] The surroundings of the Peñas del Chache were characterized by thickets of the Canarian thermophilic forest in the past.

However, historical human activity has caused its near disappearance, finding itself dominated by substitution thickets such as bitter tabaibal in modern times, dominated by the wild spurge Euphorbia regis-jubae, and the tojio thickets Asteriscus intermedius and Lavandula dentata.

[6] Nearby, archaeological remains of the ancient inhabitants of Lanzarote, the majos, have been found.
