Mexico's Yucatan peninsula is dotted with thousands of cenotes, which are sinkholes created when soft limestone bedrock collapses, exposing underground bodies of water. One of the most-loved cenotes is Hubiku.

Cenotes can vary in size and shape, with some being just a large open pool, while others are just a small entrance hole leading to a cave-like formation. Rainwater seeps through the limestone rocks, becoming filtered and leaving the underwater reservoir pure and clear. In ancient times, some of the cenotes served as ritual sites for the Maya, who believed the sinkholes were passageways to the afterlife.

Hubiku has a perfect round shape and a ceiling that has a natural opening to the surface, thus providing the cool atmosphere of a cave cenote, while still offering enough natural light from the aperture overhead. The natural light hitting the limestone formations hanging is a magical sight to behold. You might even spot some of the catfish that live in the region's cenotes.  

While Hubiku is a popular destination for tour groups, it's also an incredible natural swimming hole, making it a perfect setting for a refreshing swim and escape from the tropical heat.
