Póas Volcano

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 high. At almost a mile across Poás is the largest active crater in the world.

The park is open from 8:00 am to 3:30 pm and the best time to visit is in the morning. For more information
