The Andaman Sea opens like a wide blue road as the speedboat peels away from Phuket’s pier, spray catching sunlight and the island chain of the Similans growing sharper on the horizon. Within an hour the water flips from deep indigo to glass-clear turquoise and beneath the surface coral gardens scatter color across the seafloor. Guests step from boat ladders into warm water, fins cutting through shoals of parrotfish and wrasse while the limestone boulders of Koh Similan rise above, weathered into smooth, dramatic shapes.

The Similan Islands—named from the Malay word for nine—were designated a national park in the early 1980s to protect their unique marine and granite island ecosystems.
