VOLCANOS

Costa Rica is home to a great number of volcanoes — there are six active volcanoes and another 61 dormant or extinct ones. For the past 50 years, Arenal was the country’s most active volcano. Although it entered into a resting phase in 2010 — meaning that its eruptions have taken pause for the time being — Arenal still is one of the country’s best-known and most-visited volcanoes. There are, however, many other volcanoes that are worth exploring. Most are caldera volcanoes — volcanoes that now have a large crater, which may be filled with water and rising steam.
