The passenger boat chops away from the shore and the island shrinks into a bright crescent. You step into a padded seat beneath a porthole and feel the vessel give a gentle sigh as ballast tanks do their work. Through thick glass, the ocean pulls you down: light filters, then narrows, and the reef reveals itself as an ordered city — branching corals, curious parrotfish and a wall that drops off like an open book.

Conservation
Chankanaab is a protected marine park with fees that fund monitoring; visitors are asked not to touch coral and to use reef-safe sunscreens.
