About this tour

Upon arrival at the reception, visitors receive essential information and instructions from our expert team before being equipped for this extraordinary adventure. The descent and ascent are effortlessly managed via a winch system, requiring no manual exertion. Abismo Anhumas is a geological marvel, an incredibly rich cavern where ancient formations frame a pristine, crystal-clear lake. The sheer adrenaline and profound fascination it evokes in its visitors are instantaneous and unforgettable. You will descend 72 meters from the cave's entrance to a floating platform suspended above the lake, which plunges to depths of 80 meters at certain points. The interior of Abismo Anhumas is vast, comparable in size to a football field.

Following the thrilling descent, the group embarks on an approximately 30-minute inflatable boat tour across the lake. This segment offers a breathtaking opportunity to observe diverse geological formations, including majestic cones, delicate curtains, intricate coralloids, and towering stalactites and stalagmites. After the boat journey, visitors return to the platform to prepare for the immersive snorkeling experience. The water temperature hovers around a refreshing 18°C.

During the snorkeling adventure, you will glide around the lake's circumference. Thanks to the water's incredible transparency, you'll witness a spectacular underwater landscape, revealing submerged rock formations, such as colossal cones that reach an astonishing height of up to 19 meters.
