Sierra Negra (Galápagos)

Sierra Negra (Spanish: Black Mountain) is a large shield volcano at the southeastern end of Isabela Island in the Galapagos that rises to an altitude of 1124m. It coalesces with the volcanoes Cerro Azul to the west and Alcedo to the north. It is one of the most active of the Galapagos volcanoes with the most recent historic eruption beginning in June 2018 and continuing through the summer.

Guided tours of the volcano typically start at Puerto Villamil and traverse the rim of the caldera along its East side before heading into the fresh lava fields north east of the main crater.
