Poas Volcano National Park
Rising 2,708 meters high, the Poas Volcano is one of Costa Rica’s largest and most active volcanoes, attracting thousands of visitors each year. The volcano’s close proximity to the Central Valley, just above Alajuela, and the fact that you can drive right up to the top add to the national park’s popularity. The summit features two craters – the main crater which is 1.5 km in diameter and 300 meters deep, making it the world's largest crater, and a second extinct crater filled with blue-green cold water that is named Botos Lake (Laguna Botos). Visitors’ services include a park ranger station, trails, several natural viewpoints, and a Visitors Centre offering restrooms, drinking water, a cafeteria, small museum, and large souvenir shop.
