You step off the bus and the air changes: salt and mangrove, a wide inland silence broken by distant bird calls. The boat waits where channels cut into the peninsula, and for the next twelve hours Sian Ka'an pushes you between ecosystems—mangrove labyrinths that filter the sea and shallow reef flats that pulse with fish.
