The 1968 eruption
Arenal Volcano was born 3,000 years ago. After a long stretch of activity, it entered a dormant state lasting many centuries. Then, In 1968, it unexpectedly sprang to life again. Some villages were buried and nearly 100 people died. Arenal Volcano has remained active since then.
The park is more than
just eruption sightseeing
It has a beautiful setting that is rich in fauna and floral diversity. There are well-maintained trails for hikers and nature walkers.

It sits on the eastern side of Arenal Volcano but the lave flows you come to see occur on the western side.
The park is about 150 kilometers (80 miles) by road from San Jose, Costa Rica's capital.
