Sierra Negra, Puerto Villamil

#3 of 15 in Nature in Isabela
Volcano · Nature / Park
See the aftermath of recent lava flows at Sierra Negra, where the caldera ranks as the largest volcano on the Galápagos Islands. Since its last eruption in 2005, the shield volcano has continued to release heat and gases, without any major events. Take a guided tour to the volcano to learn about the geological phenomena that created it. If you put your hands over a hole in the mountainside, you'll feel the geothermal heat radiating from beneath the surface. Wear boots for the journey, as you might have to trek through deep mud on the way up.

  • We walked from the ranger station up to the caldera overlook. The view was amazing. We got lucky with a clear day; but even if it's cloudy, it's worth the walk - the weather changes often.  more »
  • The place is wonderful, but beware.. watch the weather. I met other travelers that payed for the tour in advance and the visibility was 5 meter. It is really a shame. I would recommend to reserve.....  more »
  • Great morning hike but don’t expect to see anything due to the fog and be prepared for rain and super muddy shoes. So not sure if the $40 volcano tour is really worth it.
  • Arriving at Sierra Negra volcano is amazing, it's huge.....a vast black carpet of volcanic rock covers it's surface, thats were its name derives from. Hiking around the crater and arriving at the northernmost is called volcan chico. In this area there are lots of small craters that are active and you see steam coning out if cracks. The views are outstanding and breathtaking. Very recommended.
