Conchagua, Extinct volcano in La Unión Department, El Salvador.

Volcán de Conchagua is a conical edifice formed by two overlapping stratovolcanoes above the Gulf of Fonseca. Cerro del Ocotal, the western peak, reaches 1225 m and is dated at 0.15 ± 0.02 Ma; Cerro de La Banderas, at 1133 m, appears younger but dates to 0.41 ± 0.1 Ma. Both peaks have active fumarolic areas, though no eruption has ever been recorded.

The volcano was settled by the Lenca civilization, who worshipped the goddess Comizahual, an indigenous jaguar princess. Lenca legends hold that Conchagua was her favourite volcano and that, on her death, she was carried to its summit, where her body turned into many golden chiltota birds. No eruptive activity has ever been recorded.

Conchagua means "flying jaguar" in the Lenca language, though other accounts derive it from Comizahual, a local heroine whose name is translated as "the tiger that flies". Lenca legend holds that Comizahual, a jaguar princess, favoured this volcano and that after her death her body was carried to its summit, where it turned into golden chiltota birds.

The best time to hike is during the dry season from November to April, when weather is stable and trails are easier to walk. The climb to Mirador Espiritu de la Montaña rewards you with views across three countries at once.

The Salvadoran government selected Conchagua as the location for Bitcoin City, a planned municipality that would use volcanic heat to power cryptocurrency mining. This makes the place where ancient geology meets modern technology.
