Sierra Negra Volcano Tour

Galapagos Alternative Sierra Negra Volcano Tour

The Sierra Negra volcano is one of five volcanos on the island of Isabela, and boasts the second largest volcanic caldera in the world (Yellowstone National Park in the United States is the largest in case you were wondering). On the Sierra Negra Volcano Tour you hike to the rim of the six mile wide crater and then trek across an alien landscape of lava fields and fumaroles. The Sierra Negra is one of the most active volcanoes in the Galapagos, with the last eruption in 2005. Though you probably won't see any lava flowing, you will have the opportunity to explore thermal vents and other fascinating geologic features before stopping for a snack near Volcan Chico. The vistas from this spot are among the most breathtaking in Isabela and on clear afternoons afford views of the northern volcanoes on Isabela and Fernandina. A savory hot lunch at Campo Duro rounds out this challenging but rewarding day.
