Poás is one of Costa Rica's most active volcanoes. The volcano is located within the Poas Volcano National Park.
It has been formed from adjoining eruptive centres with large collapse craters.
A famous eruption in 1910 sent a water geyser 4000 m into the air. Sulphur eruptions have occurred intermittently at the volcano since 1989.
