Blue holes or cenotes are underground cavities occurring in carbonate rocks that are open to the surface.
One of Belize’s most famous attractions, and an example of these, is the Great Blue Hole. Located in the lighthouse reef atoll approximately 62 miles from Belize City, it is an almost perfect circular chasm of deep blue in an azure sea. 1000 feet in diameter and more than 400 feet deep, it is the only Blue Hole on earth that is visible from space, and it’s a diver’s paradise.
Most visitors to Belize are probably unaware that in mainland Belize close to Belmopan, Belize’s capital city, and just off the Hummingbird Highway lies another of these craters, known as The Inland Blue Hole. Unlike its marine counterpart, this Blue Hole is a fresh-water cenote, located within the St Hermans Blue Hole National Park, a 575 acre forest teeming with wildlife. It is significantly smaller than the Great Blue Hole with a diameter of 300 feet and a depth of 100 feet. It’s a great spot for a refreshing dip while taking a Belizean road trip.
Belize’s third Blue Hole is still something of a secret. Located in the rainforest area on the border between the Orange Walk and Cayo districts between the Valley of Peace and San Jose, Cara Blanca is just one of a series of 25 cenotes. If you look it up on google earth the pools can be clearly seen. Cara Blanca is approximately 330 in diameter and 230 feet deep. In recent years archaeological diving expeditions have discovered pre-historic bones of huge mammals, along with Maya artifacts. The latter demonstrating how Cenotes and caves played an important part in ancient Maya culture as they were thought to be the opening to Xibalba or the underworld. The presence of a small plaza with sacrificial pots and other relics here, is thought to be evidence of this worship.
It is rumored that other Blue Holes exist in Belize. There are definitely underwater caverns behind Caye Caulker and deep blue cenotes in both southern and northern Ambergris.
Let us know if you know of any, elsewhere in the country. We’d love to hear from you.
