Do you think what to see in Costa Rica? Your attention deserves the caves of Venados. Tourists are amazed by the message of guides that the age of the caves reaches 20 million years, and that they have been under water for a long time. On the surface of the cave were due to tectonic activity. After the surface of the earth began to move under water, the caves gradually moved upward. Here you can take a good look at the amazing coral. By its structure, the caves are limestone, their vaults are compressed to the condition of a dense stone. In the cave there is an underwater river, which gives its vaults the most bizarre outlines.
