Part of the Pacific Ring Fire Circle, Costa Rica has over 200 identifiable volcanic formations dating back over 65 million years. Today, however, only 100 or so show any signs of volcanic activity, while just five are classified as active volcanoes.

Costa rica has many Volcanos to visit, both active and inactive. Some of those include : Poas, Arenal, Turrialba, Irazu, Barva, Rincon de La Vieja, and Chirripo.  Dormant ones have settlements along the ridges and can be climbed either by foot or car. The most active ones can be viewed from a distance and often put on quite a show if the weather is clear. 

Volcanoes create amazing ecosystems in tropical forests. 

Making up many mountains along the spine of Costa Rica, they push passing air upwards where it is colder, which collides with the rock and heat of the volcanos, creating clouds. Those clouds eventually fill up and drop the water back down on the volcanoes and the surrounding areas in the form of mist and rain creating incredibly lush forests.  Neighboring forests often become cloud forests because of the heavy amount of clouds passing through creating a truly magical ecosystem. All the rain results in almost steroidal growth of flora and fauna in those areas.
