Broken rock
3.5562°N 72.9369°E · pinnacle
Broken Rock is a South Ari Atoll pinnacle split by a narrow canyon you can swim through — walls of sea fans and soft coral, resident Napoleon wrasse and passing sharks. A current-swept dive from 12 m to 30 m for confident divers.
Overview
Broken Rock sits in the Dhigurah channel of South Ari Atoll, and it is named for exactly what it is: a coral pinnacle split down the middle by a canyon. That cleft — roughly 50 metres long and, at its narrowest, only a couple of metres wide — is the site’s signature, a swim-through with walls that climb well above your head. The rock rises to about 12 m and drops to around 30 m, its faces and overhangs thick with sea fans, soft coral and sponges.
The dive
The canyon is the reason to come. In calm conditions divers thread through the cleft itself, but it demands good buoyancy — the walls are close and coral-covered, and current runs stronger on the bigger tidal phases. When the flow is up, most divers work the outside of the pinnacle and hold on the sheltered side to watch the passing traffic rather than fight through the gap. Either way it is a boat dive, and the safety stop is often made in open water on an SMB.
Marine life
Napoleon wrasse are near-resident and often large — over a metre. Expect triggerfish, pufferfish, moray eels, hawksbill turtles, barracuda, and dense schools of blue-lined snapper, sweetlips and fusiliers packing the walls and overhangs. White-tip reef sharks are common; on days with good current, grey reef sharks, jacks and tuna move through. Whale sharks are an occasional visitor to South Ari as a region rather than a feature of this pinnacle.
Conditions & who should dive it
Current ranges from mild to moderate and strengthens with the tide, so this is best treated as an intermediate-to-advanced dive — most operators ask for an Advanced Open Water certification, and PADI suggests enriched air for the depth. Visibility can reach 30 m. Newly certified divers should look elsewhere; the combination of 30 m depth, a tight swim-through and current rewards experience.
When to go
December to May, the northeast monsoon dry season, brings the calmest seas and the best visibility — often over 30 m in Ari Atoll. Water sits at 26–29 °C year-round. The southwest monsoon (June–November) is plankton-rich and is South Ari’s peak season for mantas and whale sharks across the region.
Getting there
Broken Rock is a fixture of central-Maldives liveaboard itineraries and is also reached by day boat from South Ari Atoll resorts and dive centres.
