Aitutaki’s Purple Wall is a must-visit snorkelling site, known for its stunning coral formations and vibrant marine life. This lagoon hotspot gets its name from the striking purple coral lining the coral bommies in the shallow waters. Snorkellers can explore a buoy-marked area filled with colourful fish, giant clams, and breathtaking underwater scenery. Accessible only by boat, it’s one of the best snorkelling experiences in Aitutaki.
