About this site
Delwaniya Gala Diyamba is a coral-rich reef off Unawatuna on the south coast of Sri Lanka. The dive stays between 8 and 12 metres and is graded beginner to intermediate.
Visibility is excellent most of the time, which makes the reef scenic. Snappers, angelfish and giant morays are among the residents, alongside other reef species, and the site suits divers of all levels.
