On our last trip to the Galapagos, our only rainy day was on our hike up Sierra Negra Volcano on Isabela Island. We got muddy and didn’t see much of the caldera because of the fog and mist. And still we had a great time. Read more about our rainy hike up the Sierra Negra Volcano. Even in the rain, the hike wasn’t too hard. And at the top, we did get to see into the caldera, although not with a view like this.
One of our tour leaders took this picture on a recent guest excursion to Sierra Negra. As you can see, the caldera is humongous. It last erupted in October 2005 and sent an ash cloud 25,000 feet high and lava fountains reached a height of 300 meters.
