I took a guided hike on the El Silencio trail to see the volcano first. We saw some wildlife, like this tarantula making a modern home, and then we got rained on. The sound of the approaching rain was like a thunderclap, and no one in our group had jackets or ponchos except our guide. It started raining half-way through our tour, so we walked quickly back to the van. Here’s how menacing the sky looked when it was raining. Unfortunately, because of the rain I didn’t get to see any eruptions. Arenal Volcano is one of the most active volcanoes in the world and I didn’t see any lava, boohoo.
