Loh Samah Bay

This guide to Loh Samah Bay in Krabi opens on the crowded mornings of 2018, when boats queued to drop snorkelers onto the sand of neighboring Maya Bay, the cove made famous by the film The Beach, and marine biologists found only a fraction of its coral still alive. It follows the four-year closure that let divers replant tens of thousands of coral fragments and blacktip reef sharks return to the shallows. Best heard while looking across at the ridge separating the two bays.
