Poas Volcano, Poas Volcano National Park

#5 of 59 in Parks in Province of Alajuela
Observe firsthand the geothermal forces that created much of Costa Rica at Poas Volcano. Located within a national park, this active stratovolcano in the central part of the country features a giant crater over 1 km (0.6 mi) in diameter. Although the last major eruption occurred back in the 1950s, on most days you can see mud and water shooting high up into the air. These minor blowouts are caused by deposits of liquid sulphur, which wreaks havoc on the surrounding ecosystem. Just south of there you can see an inactive crater filled by a lake and surrounded by lush cloud forest. Begin your visit at the wheelchair-accessible visitor center, which marks the starting point of one of the park's main trails. Wear shoes suitable for rugged terrain, and keep in mind that due to its location above the frost line, the park often experiences below-freezing temperatures.

  • Best to check possibility to see the crater if weather allows. You are only allowed to wait around the crater for 20 minutes not long enough. Especially if the fog rolls in you will not be able to see anything. Time wasted when you could be elsewhere.
