This park is located around 12 miles northeast of Nicoya. It measures some 5,000 acres and protects an important geological resource, which is a system of caves with stalactite and stalagmite formations. The Barra Honda Peak is 1,476 ft. high and is made up of old coral reefs that were pushed up by tectonic faults.
Nineteen caves have been discovered. The Terciopelo Cave is open to the public because it is the easiest to access. The area provides a park, potable water, restrooms, lodging, an information center, trails, and lookout points where visitors can take in the scenery of the Tempisque River.
