This Costa Rican experience is truly unique. Get ready to get wet and dirty as you discover an amazing underground world. On this breath-taking expedition, you will go into the depths of the earth through a chain of caves to explore a world indifferent to light. The underground passages will take you through a maze of ancient rivers and seabeds that have now been exposed after millions of years. With flashlights to light our way, all of the necessary safety gear, and highly experienced guides, we will visit formations such as “the papaya”, “the coral”, “the altar” and “the birth canal”. We will observe the impressive stalactite and stalagmite formations which hang from the rocks, cave roof, and emerge from the ground. Please be aware that large colonies of bats, frogs, and crabs inhabit the caverns. At the end of the tour, you will enjoy fresh Costa Rican fruit as a satisfying snack.
