Scuba Season
Underwater at Ha'atafu Reef

Ha'atafu Reef

Dive site

The reef system inside Ha'atafu Beach National Marine Reserve is Tongatapu's most consistently rewarding dive. A broad coral flat at 5 to 10 metres gives way to a gentle slope dropping to 25 metres, covered in branching Acropora, massive Porites heads, and table corals sheltering clouds of anthias. Whitetip and blacktip reef sharks patrol the outer edge throughout the day, and green sea turtles rest on the sandy patches between coral heads. From July through October the reserve's shallow waters occasionally host humpback whale encounters at depth, as mothers and calves move through the channel inside the reef. The reserve's no-take status since the 1970s means fish life here is noticeably denser than on surrounding reefs.
