• Poas Volcano - The Poas is a volcano that rises to 2,708 metres above sea level, since 1989 has increased markedly the emission of gases causing acid rain phenomena that have damaged the flora in some sectors of the Park and surrounding agricultural plantations to the area. At the top there are two craters, the principal of 1.5 km in diameter and 300 deep, and the Botos lagoon, cold water and source purely rain, that drain into the Caribbean by the Angel river, tributary of the Sarapiqui River. Today the volcano emits large amount of gas and water vapor from the different fumaroles that are located in the inner cone of the crater. Identified several volcanoes, the Chompipe 2259 m above sea level, the Turu 2139 metres above the level of the sea, Cerro Cacho Negro at 2250 m and the Barva which has several craters, the well-known Tres Marias at an average altitude of 1725 meters.

Poás volcano is a powerful symbol of the geothermal forces that formed Costa Rica. When the mist and clouds part you’ll see the sulfuric, bubbling, green rain fed lake at the bottom, surrounded by smoke and steam rising from fumaroles. Water from the lake is constantly seeping through cracks in the hot rock, evaporating and building pockets of steam.

When the pressure in these pockets exceeds the weight of the water above, the steam breaks through in geysers that rocket up to 820 feet (250 meters) high. Don’t worry about getting a shower though, the crater is 1,050 feet (320 meters) deep. At almost a mile (1.6 km) across it’s also the largest active crater in the world. New safety features have been added to protect visitors in case of particularly heavy activity.
