About Ko Rangkachio
Ko Rangkachio is a small uninhabited limestone island in the Gulf of Thailand, part of Mu Ko Chumphon National Park off the coast of Mueang Chumphon District, Chumphon Province. It is notable for its rugged limestone cliffs, clear surrounding waters and fringing coral reefs. The island is undeveloped and accessed only by boat, primarily visited as a snorkeling and sightseeing stop on island-hopping tours from the Chumphon mainland.
