This park protects colossal Irazu, which, at 3,432 meters above sea level, is the tallest volcano in Costa Rica. The active volcano has a long history of eruptions. This protected area’s many geological features include the Hermosa Beach, Principal and Diego de la Haya craters, as well as the Sapper formation—the highest point in the massif, from which both Caribbean and Pacific coasts may be seen. Visitor services include information, a park ranger station, trails, restrooms, signage, a cafeteria, parking and several natural viewpoints.
