Koh Rayang Nai rises from the Gulf like an afterthought, a low green dome edged by a ribbon of sand so blonde it looks bleached. Your longtail beaches beside a driftwood log worn smooth by years of monsoon swells, and the captain points to a cluster of rocks marking the reef's edge. Ten fin-kicks from shore, you're floating above staghorn coral branching in every direction, cleaner wrasse darting between your fingers as you hover motionless.
“The reef here begins so close to shore you'll snorkel without ever losing sight of your footprints.”

The beach itself runs barely two hundred meters, hemmed in by thorny scrub and the occasional coconut palm leaning at an improbable angle. You claim a spot in the thin shade, sand still damp from the receding tide, and watch a monitor lizard drag itself lazily from the underbrush to drink from a tidal pool. The silence is broken only by the occasional slap of a needlefish skipping across the surface and the low murmur of the captain sharing cigarettes with a passing fisherman.
By the time the sun clears the scrub and heat becomes unbearable, you've already made three long snorkel transects, cataloging every anemone and angelfish. The return ride skims past Koh Kut's southern cape, and you lean over the gunwale to rinse the salt from your mask, already plotting which island in this scattered archipelago to visit next.
