Costa Rica

Arenal Volcano is the youngest and most active volcano in Costa Rica, and currently one of the most active volcanoes in the world as well. Is an stratovolcano that has been producing lava and pyroclastic flows in a continuous way since July 29, 1968; despite this activity was a danger to people living at its NW flanks in that date, today is a great attraction for thousands of tourists over the years: with good weather it delivers spectacular lava eruption nocturnal views. Even at day, thanks to its daily continuous volcanic activity, there are some remarkable eruptions that make it a great experience to witness.

Located close to the eastern extreme of Lake Arenal (northwestern Costa Rica), Arenal Volcano was considered by locals as a perfect conical shaped peak or mountain prior to its violent awakening, but at present it is known that its volcanic activity has been occurred (with dormancy periods) for the last 7,000 years. Arenal Volcano geothermal energy makes possible to enjoy relaxing hot springs and is the base for ecotourism at Arenal area.
