# Snapper Alley, Bangu Island

Snapper Alley is a dynamic dive site located at Bangu Island in Thailand’s renowned Similan Islands. This site features dramatic underwater topography with rocky outcrops and sandy channels that create an exciting exploration experience.

Divers typically encounter depths ranging from 12 to 30 meters, making it suitable for intermediate to advanced divers. The site is named for its abundant populations of large snapper fish that school throughout the area.
