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.

North of the active crater is the long-extinct Von Frantzius composite cone, the oldest crater in the central volcanic mountain range. Today it's known as Botos Lagoon. A stark contrast to the main crater, the lagoon is cool, blue and surrounded by the dense vegetation of the area's cloud forest. From the lake, a stream runs down the volcanic slopes into the Sarapiqui River.

A picturesque ride from San Jose via Highway 1 to the city of Alajuela ascending to the Volcano summit gives way to the vistas of the three main metropolitan areas of Costa Rica, the main mountain ridges that form the Central Valley and the agricultural landscape that feeds the country with coffee farms, strawberry fields and other crops.
