Anyone who's ever stayed in villas in Mexico can tell you about the white sand beaches, lush rainforests and unbelievable underwater world - but little did they know about a small, hidden sinkhole just a few miles inland that mystified the Mayans thousands of years ago.

Cenote Ik-Kil is located just around the corner from Chichen Itza and has been declared as a UNESCO World Heritage Site. Once used as a sacred meeting place by the Mayans, this 130-foot-deep sinkhole is surrounded by vine-covered trees and makes a perfect getaway for guests staying at luxury vacation rentals. Geologists estimate that the Yucatan Peninsula has more than 6,000 sinkholes, although only 2,400 are currently documented. Thousands of riverways run underground and sinkholes like Cenote Ik-Kil pop up throughout the region.

Unlike the more obscure sinkholes, Cenote Ik-Kil is easily accessible and features a high diving platform. After conquering your fear of heights, don't be afraid to cannonball into the cool, refreshing water below. If you bring a mask and snorkel, dive down as far as you can and on your way up, look toward the light rays as they pierce the crystal clear waters.
