The Poás (2708 m.o.s.l) is an active volcano, of sub conic shape, whose crest presents depressions limited by faults, volcanic cones and craters, product of recent geologic activity.

The crest of the massif presents three structures of recent formation: the main crater: the Poás, the Botos lagoon and the Von Frantzius cone. The main crater has recently and historically within the last two centuries, shown eruptive activity.



It鈥檚 located 37 km northwest of the city of Alajuela and 10 km from the community of Poasito, on the Central Volcanic Mountain Range, in Poas county, province of Alajuela, in the Conservation Area of the Central Volcanic Mountain Range.
