Frequently Asked Questions
What's the most popular dive site in Gaafu Alifu Atoll, Maldives?
The channel dives, known as 'kandus', are the most famous sites in Gaafu Alifu Atoll. Sites like Vilingili Kandu are legendary for their strong currents that attract incredible pelagic action. Divers drift along the channel edge, observing dozens of grey reef sharks, whitetip sharks, eagle rays, and massive schools of jacks and tuna. The sheer concentration of large marine life makes these drift dives the most popular and sought-after experiences in the atoll.
What are the good and less popular dive sites in Gaafu Alifu Atoll, Maldives?
Well-known sites are the thrilling channel dives that define the atoll. For a different experience, the inner atoll 'thilas' (pinnacles) and outer reefs are fantastic, less-trafficked alternatives. These sites offer calmer conditions with stunning hard and soft coral gardens, perfect for spotting turtles, Napoleon wrasse, and a vibrant array of reef fish. They provide a beautiful contrast to the high-adrenaline channel dives and are excellent for photography.
What water temperature is it like throughout the year diving in Gaafu Alifu Atoll, Maldives?
Water temperatures in Gaafu Alifu Atoll are consistently warm and tropical throughout the year, making diving very comfortable. You can expect the water to be in the range of 27°C to 30°C (80°F to 86°F). There is very little seasonal fluctuation, so you can enjoy these bath-like conditions no matter when you choose to visit.
When is the best time to visit Gaafu Alifu Atoll, Maldives?
The optimal time to dive in Gaafu Alifu Atoll is during the dry northeast monsoon, from January to April. This period brings the calmest seas, sunniest weather, and the best underwater visibility, often exceeding 30 meters. While diving is excellent year-round, this season is ideal for experiencing the famous channel dives in perfect conditions. The wet season (May-November) can offer more manta ray sightings.
What's the visibility like during the dive season in Gaafu Alifu Atoll, Maldives?
Visibility in Gaafu Alifu Atoll is generally excellent. During the peak dry season from January to April, it is common to have crystal-clear water with visibility extending beyond 30 meters (100 feet), especially in the ocean-facing channels. In the wet season (May to November), an increase in plankton may reduce visibility slightly to around 15-25 meters (50-80 feet), but this is what attracts manta rays and whale sharks.
Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in Gaafu Alifu Atoll, Maldives?
Yes, while sharks are present year-round in the channels, manta ray and whale shark sightings are more common during the southwest monsoon (typically May to November). The increased plankton in the water during this time attracts these large filter feeders. While not guaranteed, your chances of encountering these magnificent creatures are highest during these months. Liveaboards often adjust their routes to maximize these seasonal opportunities.
What marine life can I expect to see in Gaafu Alifu Atoll, Maldives?
Gaafu Alifu Atoll is a pelagic paradise. You can expect to see numerous shark species, including grey reef, whitetip, and silvertip sharks, particularly in the channels. Eagle rays, stingrays, giant trevally, tuna, and barracuda are also very common. The healthy reefs support turtles, Napoleon wrasse, moray eels, and a huge diversity of colourful reef fish. Seasonal visitors include manta rays and whale sharks.
What thickness wetsuit should I wear in Gaafu Alifu Atoll, Maldives?
Given the warm water temperatures of 27-30°C (80-86°F), a 3mm wetsuit, either shorty or full-length, is more than sufficient for most divers. Many find a simple rash guard and shorts to be comfortable. A 3mm full suit is recommended if you tend to get cold or for protection on multiple dives a day, especially during drift dives in strong currents.
How do I get to Gaafu Alifu Atoll, Maldives?
Travel to Gaafu Alifu Atoll begins with an international flight to Velana International Airport (MLE) in Malé. From Malé, you will take a domestic flight of approximately 55 minutes to Kooddoo Airport (GKK), which serves the atoll. Your resort or liveaboard operator will typically coordinate this domestic transfer and meet you at Kooddoo for the final boat transfer to your destination.
Should I book a liveaboard or stay on shore in Gaafu Alifu Atoll, Maldives?
A liveaboard is the best option to fully explore the vast and diverse dive sites of Gaafu Alifu Atoll. It allows you to access remote channels and dive multiple locations that are out of reach for resort-based operations. A resort stay is ideal for a more relaxed holiday combining diving with other activities. For divers focused on maximizing bottom time and site variety, a liveaboard is undoubtedly the superior choice in this region.
