Dhigu Thila

A dramatic pinnacle chain in Baa Atoll connected to the Anga Faru Sandbank — an underwater ridge running roughly a kilometre, narrowing to just 6 m across at its thinnest. It's made of three separate pinnacles with canyon-like gaps between them: the outer peaks rise to about 6 m below the surface, the western one to 10 m, and the deeper reef tops sit around 18 m where vertical walls drop into the blue. The western end has spectacular overhangs at several levels down to 25–30 m. Walls on both sides funnel medium current, so it's a fine drift dive. Its claim to fame is manta feeding: like nearby Hanifaru Bay, mantas gather here to feed in aggregations during plankton-rich periods — but unlike Hanifaru, diving is permitted, and lucky divers may catch their "dancing duet" courtship displays. Grey reef sharks work the cleaning stations, whale sharks turn up occasionally, and the healthy coral holds stingrays, moray eels, lionfish and abundant reef fish. Medium currents make it best for experienced drift divers, though Open Water divers can dive it when the flow is light to moderate. Best during the southwest monsoon, when manta activity peaks.
