Sierra Negra Volcano Tour
One of the largest craters in the world
The experience
Sierra Negra is an active volcano whose caldera — some 10 km across — is one of the largest on the planet. The hike follows the crater rim, with views that disappear into a black sea of solidified lava.
The route continues towards Volcán Chico, a field of cones, fumaroles and coloured lava where the 2018 eruption left landscapes that look like another planet, with views over northern Isabela and Fernandina island.
