About this audio guide
This guide to Cenote Calavera, just outside Tulum, follows the cave divers whose working lives went into mapping the flooded labyrinth beneath it, part of the vast Sac Actun system. You'll hear about Robert Schmittner, who spent fourteen years chasing one connection through zero-visibility tunnels, and about two divers who never surfaced from that same system. Best experienced looking down through the skull-shaped openings before you jump in.
