Poas Volcano
Tags volcanoes
Staring into the main crater on a clear day visitors can see the plumes of sulfuric gas and water vapor rising from the Poas Volcano. Inside the crater's center bubbles the world's largest, most acidic lagoon. The main crater is the second widest in the world, nearly a mile in length, and more than 900 feet deep with a layer of liquid sulfur at the bottom.
