The Arenal Volcano was formed about 7.000 years ago from the now extinct and adjacent Chato Volcano. It was first inactive, reason why its 1968 major eruption took the local community by surprise, burying 3 small villages and leaving 87 dead people.
Nowadays, the mighty Arenal Volcano is still active, but its eruptions are now much less severe and occur in an almost daily basis. Surrounding lands are rich in hot spring waters warmed by the volcano’s volcanic veins.
Watch the lava fall down the volcano from a safe distance while relaxing in hot spring water. An experience everybody wants to enjoy. This attraction is the reason many comfortable hotels went to the Arenal area making it highly touristic.
But that’s not all. Arenal Volcano has also a huge adjacent lake called Arenal Lake. This lake is an artificial one. After the 1968 eruption the “Old Arenal Town” was flooded to give water supply to one of Costa Rica’s biggest hydro-electric plants. This lake is perfect for water sports, boat trips, etc.
The Arenal Volcano National Park offers also vast green areas perfect for bird watching, hiking, hanging bridges, canopy, etc. Many species like, for example, the jaguar have been sighted in this National Park.
