About this audio guide
This guide to Río Secreto, the underground river outside Playa del Carmen, starts with a puzzle: why the basic facts about this cave depend on who you ask. It follows a local landowner, an iguana, and a hole in the scrub, then the explorers who spent most of a year pushing into the passages beyond. Listen where the dripping formations hang closest overhead.
