Although both volcanoes are considered dormant, there is still a great deal of geologic activity within this locale: geysers shoot water into the air and hot springs bubble up from below ground. Even better - and much more famous - is the Río Celeste, a river whose blue-tinted waters are the result of a chemical mixture produced by the Tenorio Volcano. Exploration of the Tenorio Volcano National Park is rewarding, as it hosts rivers and waterfalls amidst a dense forest setting.
These forests provide a unique habitat for animals such as ocelots and jaguars and can be toured on either foot or horseback.
