Have you ever seen a live volcano? Head to Costa Rica! The Volcan Poas (Poas Volcano) is located in Poas Volcano National Park. In this photo, you can see one of the two crater lakes that Volcan Poas boasts. This lake is called Laguna Caliente (hot lagoon!), and is one of the world’s most acidic lakes. Don’t swim here – even fish and seaweed avoid this place. Standing at the rim, you can smell the sulfur! It has been erupting for over 11 million years, although it hasn’t had much activity in the last few hundred.
