The boat slips away from An Thoi as the morning sun chisels the limestone horizons into hard edges; salt and engine exhaust stitch together with the chatter of a small crew prepping snorkeling sets. Coconut Islet appears first — bright sand, low palms and the commercial splash of Ocean World — followed by the shallow reef gardens around Gam Ghi and the mellow, swimmer-friendly coves of May Rut Trong and Ngoai.
