Isabela Island – Sierra Negra Volcano

Sierra Negra’s caldera measures six-miles across from north to south and nine-miles across from east to west, making it the second largest caldera in the world. It is a 45-minute drive from Villamil, followed by several hours of walking or horseback riding. On the rim of the volcano, the trail divides into two: to the west, it heads to Mina de Azufre, an old sulfur mine; toward the east, the trail leads to Chico Volcano.
