In 1945 a Costa Rican farmer from the village of Venado fell into a hole and discovered what is now known as the Venado Caverns.   Originally discovered by Guatuzos aborigines, the caves date back between 15 and 20 million years to the Miocene period.  For millions of years they were hidden away under the ocean, but surfaced because of tectonic movement.  There is now a series of eight different chambers open to the public which extend under ground for about a mile and half.

The caves are primarily composed of limestone, stalagmites, stalactites and corals.  An underground river is responsible for many of the interesting rock formations that can be seen.   Marine fossils are found nearly everywhere, as are numerous bats and small colorless frogs.  There is also a “shrine” with a seriously creepy glow that is of much interest.

Visiting Venado Caverns is not for the squeamish.  The caves can become quite claustrophobic and there are times when you will need to be on your hands and knees to climb through the tiny tunnels.  True exploration of the caves requires that you hike through the underground river with depths ranging from ankle to knee deep in places.  It is suggested that you bring a change of clothing and there are changing room available.  You can rent rubber boots, flashlights and lighted helmets for a reasonable fee at the cave entrance.  Tours are available that run around an hour and a half.
