The morning boat slips away from Koh Lanta's pier and the horizon opens into a palette of blue—shallow turquoise near the islands, darker navy where the Andaman deepens. Salt air sharpens the senses; the engine hum becomes part of the rhythm as guides brief new divers and check equipment. On arrival at a protected reef, the crew lowers the ladder and the water welcomes curious hands and steadying breaths.
