Galapagos Islands cruises visitor site - Sierra Negra volcano

Sierra Negra is in the west side of the Galapagos Islands archipelago. Located in the southern part of Isabela Island between the volcanoes Alcedo and Cerro Azul. Sierra Negra's caldera at 6 miles x 5 miles is the largest in the Galapagos Islands and the second largest in the world after Ngoro Ngoro.

The journey up to the crater begins at Puerto Villamil. From town you follow the road to the small town of Santo Tomas where it is possible to rent a horse. Whether on foot or by horse the trip takes between 3 - 5 hours. The landscape along the way is quite lovely. Once on top there are a series of fumaroles inside small craters. The view during the "rainy season" is quiet spectacular.

This trip is normally done as an overnight camping trip, allowing visitors to camp at the crater rim.
