Cumbre Vieja (Spanish: Old Summit) is an active although dormant volcanic ridge on the volcanic ocean island of Isla de La Palma in the Canary Islands, Spain, that erupted twice in the 20th century – in 1949, and again in 1971. The ridge of the Cumbre Vieja trends in an approximate north-south direction and covers the southern two-thirds of the island. Several volcanic craters are located on the summit ridge and flanks.
