Dhonfanu Thila dive site

Why people come here

Dhonfanu Thila sits in the channel between Dhonfanu and Fonimagoodhoo islands, a 25-minute dhoni ride from most Baa Atoll resorts. The thila itself is a submerged reef that rises from 30 metres to within 12 metres of the surface, its flanks draped in hard and soft corals. What makes it special is the way the current funnels through the channel, creating a natural conveyor belt for divers. You descend on the up-current side, drift along the reef wall, and surface near the dhoni—no strenuous swimming required. The current also brings nutrients, which is why you’ll often see grey reef sharks patrolling the deeper sections and eagle rays gliding over the coral gardens. Between June and November, mantas frequent the cleaning stations on the eastern side, especially when the plankton blooms are thick.

The dive itself

Most operators run two dives a day here: a morning drift and an afternoon manta search. The morning dive starts at 8:30, when the current is usually at its most predictable. You kit up on the dhoni, giant-stride into the blue, and descend to the reef’s shoulder at around 18 metres. The wall drops away to your left, covered in black coral bushes and gorgonians, while the shallower sections to your right are a kaleidoscope of anthias and butterflyfish. Keep an eye on the blue—grey reef sharks often cruise by at 25 metres, and schools of barracuda hang motionless above the thila like silver clouds. The drift lasts 40–50 minutes, depending on the current, and ends with a safety stop near a coral head where turtles like to nap.

Manta season

From June to November, Dhonfanu Thila becomes one of the most reliable manta sites in Baa Atoll. The eastern cleaning stations, marked by small coral heads at 15–18 metres, are where the mantas come to be groomed by cleaner wrasse. On a good day, you’ll see three or four mantas circling the stations, their wings casting moving shadows over the reef. The best encounters happen when the current is running—it brings plankton, which brings mantas. If the water is murky with plankton, don’t worry; the mantas will still be there, just harder to spot until they glide into view. Some resorts offer a manta search dive in the afternoon, when the light is better for photography.

Who should dive here

Dhonfanu Thila is well suited to divers with at least an Open Water certification and some drift experience. The current can be strong, especially on the outgoing tide, so you need to be comfortable with buoyancy and quick descents. If you’re new to drift diving, most resorts will pair you with a guide who can help you manage the current. Advanced divers will love the deeper sections, where grey reef sharks and occasional hammerheads patrol. Photographers should bring a wide-angle lens for mantas and a macro for the nudibranchs that hide in the coral crevices. Night dives are rare here, but if your resort offers one, it’s worth it for the chance to see sleeping parrotfish and hunting lionfish.

Resorts with easy access

Most Baa Atoll resorts can reach Dhonfanu Thila within 25–40 minutes by dhoni. The closest are Amilla Maldives, Finolhu, and Four Seasons Landaa Giraavaru, all of which include the site on their standard dive itineraries. Amilla’s dive centre, for example, runs a morning drift dive here three times a week, followed by an afternoon manta search. Finolhu’s Splash Water Sports offers a ‘Manta & Thila’ combo package that includes two dives at Dhonfanu Thila and a snorkel trip to Hanifaru Bay. If you’re staying at a resort in a different atoll, ask about day trips—some operators in North Malé Atoll run overnight dive safaris that include Baa Atoll sites.

The honest bit

Dhonfanu Thila isn’t a site for absolute beginners. The current can be unpredictable, and the reef’s deeper sections require good air management. If you’re not comfortable with drift diving, start with a shallower site like the house reef at your resort. Visibility varies—on plankton-heavy days, it can drop to 10 metres, which makes spotting mantas trickier. The site is also popular, so you might share the water with other dhonis, especially in peak season. That said, the reef is large enough that you can usually find a quiet corner. Lastly, while mantas are common, they’re not very likely. If you’re set on seeing them, plan your trip between August and October, when sightings are most frequent.

What to bring

A reef hook is useful for anchoring yourself to the coral during strong currents—most dive centres provide them, but bring your own if you have one. A surface marker buoy (SMB) is essential for safety stops, especially if the current carries you away from the dhoni. For photography, a wide-angle lens is best for mantas and sharks, while a macro lens will capture the nudibranchs and shrimp that hide in the coral. If you’re prone to seasickness, take motion sickness pills before the dhoni ride—Baa Atoll’s channels can get choppy.
