Dharavandhoo Thila
5.1612°N 73.1219°E · thila
Dharavandhoo Thila is Baa Atoll's scuba-accessible manta dive — a protected cleaning station near Hanifaru Bay where reef mantas queue over the reef to be cleaned. Overhangs of sea fans, garden-eel sand flats, and one of the Maldives' great manta encounters, roughly May–November.
Overview
Dharavandhoo Thila lies off Dharavandhoo island in Baa Atoll — the Maldives’ only UNESCO Biosphere Reserve — a short hop from the world-famous Hanifaru Bay. The thila was designated a Marine Protected Area in 2023 to protect the atoll’s globally significant manta population, and it earns the status: as of 2020, official records logged 521 individual mantas and more than 1,600 sightings here. Its great value is simple — because scuba diving is banned in Hanifaru Bay (snorkelling only), this is where you can watch mantas on scuba.
The dive
The thila has two faces. The outer side is a sand flat alive with garden eels and shrimp-gobies; the inner side is a run of dramatic overhangs draped in colourful sea fans, with cleaner wrasse, shrimp, morays, lionfish, scorpionfish and clouds of anthias. The manta cleaning station sits around 20 m, where reef mantas rise from deeper water and circle patiently above the cleaning rocks — divers kneel on the white sand below and watch, without chasing or touching.
Marine life
Reef mantas are the reason to come. Nurse sharks and lobster shelter in the overhangs by day, grey reef sharks and big tuna pass by with luck, and Napoleon wrasse and large groupers work the sand. Glassfish, octopus and reef fish fill in the rest. Whale sharks are associated with Baa Atoll as a region — mostly around Hanifaru — rather than this thila.
Conditions & when to go
This is a manta season dive, and Baa runs opposite to most of the Maldives: the mantas gather on the southwest monsoon, roughly May to November, when nutrient-rich currents drive plankton blooms into the atoll (the peak is often around July–October). Visibility is around 30 m, water 27–30 °C. It’s a fairly accessible thila dive, though current and the 20 m+ depth make it best for divers comfortable with both.
Getting there
Dharavandhoo has its own domestic airport (about a 20-minute flight from Malé) and local dive shops such as Blue World; Baa Atoll resorts and manta-season liveaboards also dive the thila. Note that Hanifaru Bay itself, five minutes away, is snorkel-only and ranger-controlled.

Baa Atoll's Hanifaru Bay hosts one of the world's largest known reef manta feeding aggregations; the Manta Trust's ID database has logged thousands of individuals feeding here during the southwest monsoon plankton blooms.
