Orimas Thila dive site, Ari Atoll

Why people come here

Orimas Thila isn’t just another dive site—it’s a masterclass in Maldivian marine biodiversity. The thila (a Maldivian term for a submerged reef) is shaped like a giant horseshoe, with a shallow plateau at 8–12 metres and walls that drop to 30 metres. The top is covered in hard coral tables, some wider than a king-size bed, and the sides are pocked with caves and overhangs. Grey reef sharks patrol the edges, while schools of fusiliers and anthias dart between the branches of black coral. On the eastern side, there’s a cleaning station where mantas and eagle rays come to be groomed by wrasses. The current here is usually mild in the morning, making it well-suited to Open Water divers, but it can pick up in the afternoon, which is when the big stuff shows up. The visibility rarely drops below 20 metres, and in the dry season (November to April), it can exceed 40 metres. That’s why I always recommend a wide-angle lens—you’ll want to capture the full scale of the place.

What you’ll see underwater

The star attractions at Orimas Thila are the grey reef sharks. They’re not shy here; you’ll often see them cruising along the wall or resting in the sand at the base of the thila. Eagle rays are another common sight, especially near the cleaning stations. Look for their white-spotted wings as they glide past. The coral is some of the healthiest in Ari Atoll, with massive table corals, brain corals, and black coral bushes that host pygmy seahorses. If you’re lucky, you might spot a hawksbill turtle or a Napoleon wrasse. The swim-throughs are a highlight—there’s one at 15 metres that’s wide enough to pass through with a buddy, and another at 22 metres that opens into a small chamber. The walls are covered in soft corals and sponges, and if you shine your torch into the crevices, you’ll see lobsters, moray eels, and nudibranchs. The thila is also home to a resident school of barracuda, which often hang motionless near the surface at the end of the dive.

Best time to dive

Orimas Thila is diveable year-round, but the conditions vary with the seasons. From November to April, the northeast monsoon brings calm seas and excellent visibility. This is the best time for photography and for seeing mantas at the cleaning stations. The water temperature hovers around 28°C, and the current is usually mild in the mornings. From May to October, the southwest monsoon brings stronger winds and occasional rain, but the diving is still good. The visibility can drop slightly, but the current picks up, which brings in more sharks and rays. This is also the best time to see whale sharks in Ari Atoll, though they’re more common at sites like Maamigili Beyru. If you’re diving in the monsoon season, Worth recommending: a 5mm wetsuit—the water can feel chilly after an hour. Mornings are always better than afternoons; the light is softer, and the marine life is more active.

How to get there

Orimas Thila is accessible by liveaboard or day trip from resorts in Ari Atoll. Most liveaboards include it on their itineraries, especially those focused on shark diving. The site is about 30–45 minutes by dhoni from resorts like Conrad Rangali Island, Veligandu Island Resort, or Nika Island Resort. If you’re staying at a resort, Worth recommending: booking a two-tank dive trip so you can visit Orimas Thila in the morning and another site like Fish Head or Maaya Thila in the afternoon. The boat ride is part of the experience—you’ll often see dolphins or flying fish along the way. For liveaboard guests, the site is usually dived in the morning, with a second dive at a nearby thila or channel in the afternoon. Transfers from Malé to Ari Atoll resorts are by speedboat or seaplane, depending on the resort’s location. Most resorts offer shared or private transfers, and I can arrange these for you.

Who it suits

Orimas Thila is well suited to divers of all levels, but it’s especially rewarding for those who’ve logged at least 20 dives. The site is forgiving enough for Open Water divers, but Advanced divers will get more out of the deeper sections and swim-throughs. Photographers love it—there’s always something to shoot, whether it’s a shark patrolling the wall or a pygmy seahorse hiding in the black coral. Fede guides couples who want to share a memorable dive, families with teenage kids who are comfortable in the water, and solo travellers looking to meet other divers. If you’re a beginner, Worth recommending: doing a check-out dive at your resort’s house reef first to get comfortable with the conditions. For non-divers, some resorts offer snorkelling trips to the top of the thila, where you can see reef sharks and rays from the surface. Just be aware that the current can be strong, so it’s not well-suited to weak swimmers.

The honest bit

Orimas Thila isn’t a site for those who prefer calm, shallow dives. The current can be unpredictable, and the deeper sections require good buoyancy control. If you’re not comfortable with drift diving, this might not be the site for you. The visibility is usually excellent, but it can drop after heavy rain, especially in the monsoon season. The site is also popular, so you’ll often share it with other boats. That said, the thila is large enough that you won’t feel crowded. The swim-throughs are safe, but they’re tight in places—if you’re claustrophobic, you might want to skip them. The marine life is incredible, but it’s not a very likely. Some days you’ll see 20 sharks; other days, you might only see a few. That’s the nature of wildlife. Finally, the boat ride can be rough in the monsoon season, so if you’re prone to seasickness, bring medication. I always tell clients to pack a reef hook—it’s the best way to stay in one place and watch the action without kicking up sand.

Resorts with easy access

If you want to dive Orimas Thila as part of a resort stay, these are the properties I recommend. Conrad Rangali Island is a 35-minute seaplane ride from Malé and offers day trips to the site. The resort has a PADI 5-star dive centre with excellent guides and a house reef that’s great for check-out dives. Veligandu Island Resort is another good option—it’s a 20-minute seaplane ride from Malé and has a relaxed, beachy vibe. The dive centre here is run by Euro-Divers, and they offer small-group trips to Orimas Thila. For a more luxurious experience, Nika Island Resort is a 25-minute seaplane ride from Malé and has a PADI Gold Palm dive centre. The resort is adults-only, so it’s quieter than some of the family-friendly options. If you’re staying in North Ari Atoll, I’d also recommend Reethi Beach Resort—it’s a 30-minute seaplane ride from Malé and has a great dive centre with knowledgeable instructors.

Liveaboard options

Liveaboards are the best way to dive Orimas Thila if you want to explore multiple sites in Ari Atoll. Most liveaboards include Orimas Thila on their itineraries, along with other top sites like Fish Head, Maaya Thila, and Broken Rock. The Maldives Aggressor is a popular choice—it’s a 38-metre yacht with 11 cabins and a spacious dive deck. The Emperor Voyager is another great option; it’s a 35-metre boat with 17 cabins and a relaxed atmosphere. For a more intimate experience, the Carpe Vita is a 33-metre schooner with just 7 cabins. All of these liveaboards offer nitrox, which is a bonus for longer dives. I can help you choose the right liveaboard based on your budget, travel dates, and diving experience. Most liveaboards depart from Malé and include transfers from the airport.
