Deal overview
If you like extreme challenges, we invite you to explore the San Jerónimo underground river which is a little more challenging due to its characteristics. We say this because it has more water than other rivers that we usually travel and the caves are larger so we will test your skills and dexterity at every step.
We will begin this expedition in the Cacahuamilpa Caves, where through a walk, we will enter the river. Already prepared and reaching the shore... to the water ducks! , we will have to swim to the entrance to the cavern. Take advantage of the landscapes, take a breath, immerse yourself and discover the rock formations that hide these caves.
Walk carefully in the dark on sand dunes, it will be an incredible experience. The darkness, gloom and formations will be the protagonists of this adventure. You will also be able to identify aromas and different temperatures inside these ancient caverns. Don't worry, it is not an experience that can scare you, on the contrary, all the mystery that surrounds this place will give it an extra touch of adventure.
Leaving this dark path where, without flashlights, you don't see a hand in front of your eyes, we will head to enjoy a delicious local meal. There we will recover the energy spent during this experience.
You will be accompanied by the best instructors, who will take you on an expedition full of emotions. We will also provide you with a life jacket, helmet, flashlight and backpack on loan during the experience.
Shall we reserve your place?
