Puerto Rico is home to some of the most fascinating caves in the world and one of the biggest sinkholes in the world, Tres Publeos". The Rio Camuy is one of the largest underground rivers in the world and for the last 30 years, the system has been mapped and photo documented. There is a section where the river loses without a hint in sight but in the rain forest, a cave might hold the missing piece to the lost Rio Camuy system.
