Rumors existed since 1935 among the inhabitants of Venado de San Carlos, that there were caves nearby. But they were not discovered until 1945. Today, 8 caverns have been mapped totaling over 2,700 meters. Each of the caverns has sufficient headroom to permit explorers to remain standing while a few of them are 35 meters tall. The main entrance is located just 2 kilometers from the center of the town of Venado in San Carlos. In your trek through the caves, you will be able to observe water as it permeates the upper rock and drags with it calcium carbonate to form the staglatite while constantly dripping to the floor to shape staglamite.
