The reef at Alimatha changes after sunset. Nurse sharks, stingrays and trevally come in to feed, and a night dive puts you on the sand beside them. Dive centres run the trip for certified divers, usually after a briefing and a check of your torch.
01
What happens after dark
Alimatha sits in Vaavu Atoll, south of the Malé atolls. By day the reef is quiet. After dark, nurse sharks move in over the sand and reef edge, resting on the bottom in numbers. Stingrays and trevally are often seen on the same dive, and the torch beam picks out sleeping fish and coral polyps opening.
The dive is usually shallow and slow. Groups kneel or hover on the sand while the sharks settle around them. Guides keep the group together and control where lights point, because bright beams and sudden movement disturb the animals.
This is a night dive, so the reef looks different from the day sites you may know. Colours fade, shapes matter more, and the beam becomes your main tool. A guide who knows the site will show you where the sharks gather and how to approach without crowding them.
02
Who can join
The dive is run for certified divers. Some dive centres ask for a recent dive log or a check dive first, especially if you have not dived for a while. Others accept any certified diver who joins the boat. Rules vary between operators, so ask when you book.
You need a torch, a briefing and a buddy. Most centres provide torches and tanks, and some include a backup light. If you have your own torch, bring it and check the batteries before the boat leaves.
Night diving is not difficult, but it is different. If you are newly certified or nervous in low light, say so. A good centre will pair you with a guide or a more experienced buddy and keep the group small.
- Certification: open water or above, as set by the dive centre.
- Recent dives: some centres ask for a check dive or recent log.
- Torch: provided by many centres, or bring your own.
- Buddy: you dive with a buddy or a guide.
- Briefing: given before the boat leaves, covering lights and signals.
03
Booking through a dive centre
Night dives at Alimatha are arranged through dive centres based in Vaavu Atoll or on liveaboards passing through. There is no public access to the site, and the trip depends on the operator's schedule, the weather and the number of divers.
Ask what is included: torch, tank, weights, guide and boat. Some centres charge extra for equipment hire. Confirm the meeting time and whether the boat returns the same evening.
Conditions change. A centre may cancel a night dive if the sea is rough or the group is too small. Build a spare night into your stay if the dive matters to you.
04
In the water
The guide briefs the group on entry, the route and the signals to use. Torch signals replace hand signals at night: a circle of light means OK, a waved beam means attention. Keep your beam low and away from other divers' eyes.
Stay close to your buddy and the group. The reef is shallow, and it is easy to lose orientation in the dark. Follow the guide's line and do not swim off on your own.
Maldives regulations cap recreational diving at 30 metres. Night dives at Alimatha are usually much shallower, but the limit applies. Do not touch or stand on coral, and do not feed the fish.
05
Sharks and reef care
Nurse sharks are large but docile. They rest on the sand and do not need to be chased or handled. Keep a respectful distance, let them settle, and follow the guide's positioning. Touching or blocking them causes stress and spoils the dive for others.
Stingrays and trevally may pass close. Keep your fins off the bottom and your beam steady. Stirring up sand reduces visibility for everyone and can bury small coral.
The same reef rules apply at night as by day. Do not collect shells or coral, and do not take anything out of the country. A torch beam should light the animal, not blind it.
06
Practical points
Vaavu Atoll is reached by speedboat from Velana International Airport, which suits the atoll's distance from Malé. Some visitors arrive by liveaboard. Transfers are arranged by the resort or dive centre, and timings depend on the island and conditions.
The dive runs all year, but the monsoons change conditions. Iruvai, the northeast monsoon from roughly December to April, is drier and calmer. Hulhangu, the southwest monsoon from roughly May to November, brings windier weather and choppier crossings. Air and sea stay warm all year.
Bring a rash guard or thin wetsuit for the boat, and dry clothes for the return. A small waterproof bag for a phone is useful. Check with the centre about what to bring and where to meet.
- Access: speedboat from Velana, or liveaboard.
- Season: all year, calmer in Iruvai.
- Bring: rash guard, dry clothes, waterproof bag.
- Check: meeting point and return time with the centre.
