Dhonfanu Thila Diving: Mantas, Sharks & What to Expect
Dhonfanu Thila doesn’t have the name recognition of Hanifaru Bay, but ask a dive guide working Baa Atoll which pinnacle they’d send an experienced diver to, and this is one of the first names that comes up. It’s a UNESCO-protected reef built around a single dramatic swim-through, regular manta encounters, and a current strong enough to keep things interesting.
This guide covers exactly what the dive looks like — depth, current, topography — the marine life you can expect, the best season, and who this site genuinely suits.
| ✍️ “What makes Dhonfanu Thila iconic in dive logs is entering the narrow swim-through at 25 metres and exiting into a calm pocket filled with glassfish, right before hanging on the point as grey reef sharks and mantas ride the current above.” |

1. What Is Dhonfanu Thila?
Dhonfanu Thila is a submerged pinnacle near Dhonfanu Island in Baa Atoll, part of the UNESCO Biosphere Reserve designated in 2011. The thila rises from well over 40 metres to within roughly 8–10 metres of the surface, creating a dramatic vertical reef rather than a flat plateau.
🏆 Widely regarded as one of the standout named dive sites within Baa Atoll, alongside Dhigali Haa (Horubadhoo Thila) and Nelivaru Haa
🛡️ Protected under Baa Atoll’s UNESCO Biosphere Reserve status, with regulations against fishing and anchoring damage
🕳️ Best known for a narrow swim-through connecting two sides of the pinnacle — the site’s signature feature
| 💡 Pro Tip: If you’ve already read our Baa Atoll Diving guide, Dhonfanu Thila is one of the specific named sites worth requesting by name when booking a liveaboard or resort dive trip through the atoll — it isn’t always included on every itinerary by default. |

2. Where Is It & How Do You Dive It?
Dhonfanu Thila sits in Baa Atoll, in the northern Maldives, reachable by day boat from Baa Atoll resorts or as a scheduled stop on liveaboard itineraries that route through the northern atolls.
🏝️ Closest to Dhonfanu Island, with several Baa Atoll resorts running it as a standard day-boat dive
⛵ Frequently included on liveaboard ‘North Atolls’ or ‘Best of Maldives’ itineraries alongside Hanifaru Bay (snorkel-only) and other Baa Atoll thilas
| ⚠️ Not the Same as Hanifaru Bay: Dhonfanu Thila is a scuba dive site with no entry restrictions beyond standard reef protection rules — this is different from Hanifaru Bay itself, which permits guided snorkelling only. Don’t confuse the two when planning a Baa Atoll trip; see our Baa Atoll Diving guide for the full breakdown of what’s diveable versus snorkel-only across the atoll. |

3. Dive Profile: Depth, Current & Topography
This is a current-driven dive built around the pinnacle’s point, which faces into the prevailing current and splits it down either flank of the reef.
| Detail | What to Expect |
| Typical Depth Range | Point of the reef around 22m; swim-through base around 25m, ascending to an 18m entrance |
| Current | Moderate to strong, current-driven drift dive — divers typically drop in ahead of the thila to let the current carry them to the point |
| Signature Feature | A narrow swim-through leading into a calmer pool with lighter current, rich in reef life |
| Visibility & Water Temp | Generally good visibility; water temperature 26–29°C (79–84°F) year-round |
| ⚠️ Current Experience Required: The drop-in technique and point current here mean this isn’t a first-dive site. Divers should be comfortable with drift diving and current management before booking Dhonfanu Thila specifically — ask your dive guide directly if you’re unsure your experience level is a good match. |

4. Marine Life at Dhonfanu Thila
🌀 Manta rays — regularly sighted in season, one of the more reliable manta encounters in Baa Atoll outside Hanifaru Bay itself
🦈 Grey reef sharks and eagle rays cruising the deeper sections of the reef
🐢 Green turtles reported on the shallower sections and swim-through area
🐠 Dense schools of moon fusiliers and broad-striped fusiliers cascading around the reef edges, plus anthias, basslets, and dottybacks holding in the current on top of the thila
🐡 Reef life in the swim-through’s calmer pool — cleaner wrasses, triggerfish, parrotfish, butterflyfish, and soldierfish
| 💡 Pro Tip: For the full picture on manta season timing across Baa Atoll — including Hanifaru Bay’s separate snorkel-only rules — see our dedicated Manta Rays in the Maldives guide before booking around a manta encounter here specifically. |

5. Best Time to Dive Dhonfanu Thila
Diving is possible at Dhonfanu Thila throughout the year, but conditions and manta odds shift by season.
☀️ January–May (dry season): generally considered the better window for diving conditions and visibility
🌧️ June–November (rainy season): diving remains possible, and this period overlaps with Baa Atoll’s broader manta and whale shark aggregation season (peaking late July to early October) — see our Baa Atoll Diving guide for the full seasonal breakdown
| 💡 Pro Tip: If manta encounters at Dhonfanu Thila specifically are your priority, weigh the trade-off directly: the peak manta window (roughly June–October) falls outside the calmest dry-season visibility window (January–May). |

6. Who Should Dive Here?
| Good Fit | Better Suited Elsewhere |
| Advanced divers comfortable with drift diving and point currents | Newer divers still building current experience and comfort |
| Divers who want a genuine swim-through feature, not just a wall or slope | Divers prone to anxiety in tight, narrow underwater passages |
| Manta-focused divers looking for odds beyond Hanifaru Bay’s snorkel-only zone | Divers who specifically want a guaranteed, non-seasonal encounter — mantas here are seasonal, not year-round certain |

7. Frequently Asked Questions
Q: How deep is Dhonfanu Thila?
A: The main point of the reef sits around 22 metres, with the site’s signature swim-through starting at roughly 25 metres and ascending to an 18-metre entrance. It’s a dive best suited to divers comfortable at these depths with current.
Q: Can you see manta rays at Dhonfanu Thila?
A: Yes — it’s one of the more reliable manta sightings in Baa Atoll outside Hanifaru Bay itself, though sightings are seasonal rather than guaranteed year-round. Peak manta activity in the wider atoll runs roughly late July to early October.
Q: Is Dhonfanu Thila the same as Hanifaru Bay?
A: No — they’re different sites in the same atoll. Hanifaru Bay permits guided snorkelling only, while Dhonfanu Thila is a standard scuba dive site with no such restriction. See our Baa Atoll Diving guide for the full breakdown.
Q: Is Dhonfanu Thila suitable for beginners?
A: Not really. The site’s drop-in technique, point current, and narrow swim-through are better suited to divers with solid drift-diving experience rather than newly certified beginners.
Final Word
Dhonfanu Thila earns its reputation the way most great dive sites do — through a mix of good topography, reliable marine life, and just enough current to keep a dive interesting rather than easy.
If you’re building a Baa Atoll itinerary around Hanifaru Bay’s snorkel-only manta encounters, make sure Dhonfanu Thila is on the dive list too — it’s the site that lets you actually scuba dive with the same marine life the bay is famous for.
A UNESCO reef, a real swim-through, and mantas in season — worth requesting by name.
