We start with a 45-minute drive to the private estate where the caves are located. Upon arrival, you'll receive a flashlight, helmet, and rubber boots (size 11 and larger must wear their own shoes). Our naturalist guide will begin with a brief history of the caves before delving into the depths of this incredible journey. A walk that reveals the amazement at the river that runs from the underground labyrinths to the entrance of the cave.

There are no lights or walkways, giving the feeling of being the first to explore. Turn on your flashlight, jump into the river and watch out for those spiders on the walls! There is no way back. It's a bit difficult to walk along the river, but that's just part of the adventure. Get ready to go through small holes, crawl through narrow passages, climb small rock formations and walk through small waterfalls. Feel the air move around your face as the bats fly right over your head. Notice how they have carved their nests out of solid rock. Enjoy the numerous stalactites, stalagmites, corals and chimneys as if you were traveling back in time.

The rock called "Papaya" is spectacular. This is an experience you will never forget! It is recommended only for people in good physical shape. What to bring: Please wear pants and an old shirt, no jewelry, bring cotton socks for rubber boots, extra clothes, towel, and soap.
