Tourists watch a newborn blacktip reef shark at the beach in Maya Bay at the Phi Phi Island National Park, on Phi Phi Leh Island, Krabi province, Thailand, February 25, 2023. Under pressure from tour operators, authorities reopened Maya Bay in January 2022 after four years of closure, and visitor and revenue figures are once again rising steadily. But authorities have maintained restrictions on access. Tour boats must dock on the other side of the island from the beach; visitors must walk to the beach; the number of visitors allowed every hour is capped at 375, and they are allowed to wade only knee-deep into the water.
