Don your wet suit, helmets, water shoes and head lamps and prepare to marvel at this natural miracle. The story behind the Rio Secreto goes as follows: This underground system was discovered by a Mexican farmer who was shifting some rocks, chasing an iguana. He chanced upon a hole which caught his interest as he thought it was a sacred cenote. Cenotes are places of worship and reverence in Mexican culture, doorways to the underworld and sources of pure water. On digging deeper, he opened the gates to a spectacular underground cave system formed by a river forking through the ground. This system, the Rio Secreto, had been lying hidden for over two million years.
Since its discovery The Rio Secreto has become one of the most renowned and vast systems of cenotes in the world. The natural crystal and stalagmite formations lie illuminated by the light reflecting off the pristine waters, making it a most outlandish landscape. The Rio Secreto, is a perfect spot for adventurous swimming as guests walk through passageways riddled with limestone formations, heading on to wade through sparkling blue waters and exploring the life and formations underwater. The seemingly never-ending ceiling of stalactites holds stories of the ancient earth and its movements several centuries ago, along with a few beautiful fossil formations.
