About Snapper Alley
Snapper Alley is an easy Similan reef on the southeast side of Koh Bangu, built around granite boulders, sloping hard coral, and swim-through features. It is a good fit for calm-day fun dives and night dives, with mild currents, clear water, and big snapper schools alongside turtles, rays, and other reef life. It is a regular highlight on Similan itineraries because the reef stays approachable without feeling plain.
