in the country. It was believed to be dormant until a major eruption in
1968.
The park is next to the country's largest hydroelectric project, the
Arenal
Lake Dam.

flora
and fauna species in multiple life zones, innumerable rivers,
waterfalls and thermal hot springs.
The

exhibition hall, a
souvenir store, and restrooms. Marked hiking trails lead to various
points
of interest and scenic overlooks (see trail map above) Arenal Costa
