Ko Raya Noi
Island
Raya Noi, south of Phuket, is a low-lying island known for clear water and dive sites; day-trip boats bring snorkelers and scuba divers to its reefs.
Ko Raya Noi (Raya Noi) is the smaller Racha island located to the south of Phuket in the Andaman Sea. The island is a low-lying, reef-fringed destination noted for clear water and snorkeling close to its beaches.
Day-trip services and speedboats from Phuket’s Chalong Pier and other nearby harbors provide the main access, and visitors come for swimming, snorkeling, and short beach stays rather than extensive resort infrastructure. The island has limited development compared with its larger neighbour, Racha Yai.
Historically the island remained sparsely developed; tourism activity has been centered on day trips and small-scale accommodation rather than large hotels. Marine conditions and nearby reefs make it a common spot for snorkel and dive outings.
Ko Raya Noi sits southwest of Phuket in the Andaman Sea and is approached by boat from Phuket’s east-coast piers.
- Snorkeling and access: Part of the small Racha (Raya) island group south of Phuket, it is known for clear water and snorkeling close to its shores and is commonly visited on day trips from Phuket's Chalong Pier.
Tips for Visiting Ko Raya Noi #
- Take a dedicated day-trip boat from Chalong or scheduled dive/snorkel operators in the morning when visibility is best and operators run fewer, more direct runs.
- Plan for minimal facilities on the island - boats typically anchor offshore and you'll transfer by dinghy, so book with an operator that provides gear and a clear landing plan.
