The Sierra Negra volcano has one of the largest crater in the world, with a diameter of 10 km. This volcano, still active, experienced its last eruption in June 2018. One of the superb hikes to do takes you from the Sierra Negra volcano to the Chico volcano, through a variety of vegetation and offering spectacular views of the entire island. This is one of the most beautiful long hikes in the entire archipelago.
Another hike takes you to the other side, to the sulfur mine where you will observe the fumaroles coming out of the active volcano, as well as the mountain covered with the characteristic yellow sulfur. This 3.5 km trail crosses magnificent volcanic landscapes. The drive from Puerto Villamil to the trail entrance takes approximately 45 minutes.
