Dive-site story
Lying south of Phuket, Racha Noi is uninhabited and known for dramatic granite boulder formations reminiscent of the Similan Islands. Submerged pinnacles, sweeping drop-offs, and sheltered eastern bays offer varied profiles across the island. The site often attracts pelagic visitors passing through open Andaman Sea currents.
Granite boulder swim-throughs and jagged underwater topography
High chances of encounters with oceanic manta rays at the southern tip
Sheltered bays with hard coral gardens suitable for less experienced divers
Location
Use the map to plan with your operator and confirm the exact entry point on the day.
Seasonality
The northeast monsoon brings calm seas and peak pelagic activity, though diving runs year-round in sheltered bays.
