Huvadhoo Atoll also known as Gaafu Atoll in the Maldives, a world-renowned diving destination. The crystal clear waters coupled with stunning underwater topography, and an abundance and diversity of marine life that you will find hard to believe until you've seen it with your own eyes. Colourful reef fish, large pelagics, photogenic macro subjects and beautiful corals all await your company. Whether you enjoy an exhilarating drift dive, a calm easy going exploration of a shallow reef or looking for sharks in the channels – there is something for everyone. There's a wealth of exciting dive sites waiting to be explored in this area, including colourful coral reefs, outcrops, dramatic walls, caves, tunnels, thilas (underwater islands) and fascinating channels.

Huvadhoo is the second largest atoll in the Maldives covering an area of almost 3,000 square km. The atoll's central lagoon is 40 miles (65km) across at its widest point and up to 279 feet (85 meters) deep. There are more than 230 islands at the center of its lagoon - more than any other atoll in the Maldives. It is fringed by a well-defined and almost continuous rim-reef with a deep lagoon. This atoll is a paradise for underwater adventures with scores of healthy coral islets and still undiscovered dive sites. Many of the vibrant reefs and lagoons remain unexplored, visitors here include stingrays, large numbers of turtles and a variety of sharks including black and white tip reef sharks, nurse sharks and occasionally hammerheads and tiger sharks.

The feature of the most of the atoll's dive sites is inconspicuous caves and caverns, which hide in the variety of drop-offs. Untouched rocky formations shelter many tiny underwater species, which are a godsend for macro photographers. Diving in the area is a complete pleasure, as depth range is from 8m/25ft till 30m/100ft. The substantial outer reef forms a natural barrier to the ocean's currents, and diving options are available for both beginners and advanced divers. Most of them are accessible by boat. Divers can enjoy their diving in such dive sites as Nilandhoo Kandu, Hafsa Thila, Vadhoo Thila, Kaaddhedhoo Kandu and Mofzaa Thila. All of dive spots impress with the amount of rock-formations and dense corals covering the reef.

The isolation comes from the 97 kilometer wide channel north of Huvadhoo Atoll known locally as Huvadu Kandu. It is the broadest channels between atolls anywhere in the Maldives making it a popular route for liveaboards in the Maldives. Along this channel are many low coral islands. To the south is the 49 kilometer wide Addoo Kandu (South Equatorial Channel).

During the long period of time Huvadhoo Atoll served as a trading point or a stop-by place for mariners. Administratively  Huvadhoo  is divided into two regions: Northern Huvadhoo Atoll and Southern Huvadhoo Atoll. There are not so many places for sightseeing. The most popular are Buddhist remains, scattered around both of the regions. Due to its isolation, Huvadoo Atoll also has its own dialect known as "Huvadhoo Bas." The locals are known for their friendliness and hospitality and for the top quality woven mats they produce from the local grass, 'hau' dyed black and yellow. Thousands of tourists choose this tropical destination with another aim – to relax in top-class resorts, sun-bath on palm-fringed beaches and dive in pristine ocean waters. Away from the resorts and underwater restaurants, divers choose this place to admire the vast coral reefs, which strike with colors and the diversity of marine species.

If you're lodging on the Huvadhoo Atoll, then you will transfer by domestic flight (one hour) to either Kooddoo in the north or Kaadhedhoo in the south from Male Airport. It depends on where you're staying.

This is a very small and interesting dive site. It is totally different from other dive sites in this area. The top reef starts at 10 meters with a big coral block on top that comes up to 6 meter below the surface. On Kuda Hafsa Thila you will find a vast amount of fish, ranging from small bait fish to big tuna. Here you can also find a resident school of yellow and blue striped snappers. Sharks are regularly spotted and so are turtles. Keep your eyes peeled for the little leaf fish.


This is a classic outreef dive site. The reef starts on 5 meter and slopes down to around 15 meters, then drops down to 40 meters like a wall. This dive site is covered with beautiful corals and a lot of different reef fish. The best thing about diving on this outreef is that just about anything can make an appearance, so keep your eyes peeled and look into the blue, as big fish regularly pay a visit! Turtles, sharks, tunas, barracudas and napoleon wrasses are commonly spotted as you drift along with very little effort.

During the month of January – April, there is a special site near to Mercure Kooddoo to do night snorkeling with Whale Sharks. A special lighting technique is used to attract zoo plankton to the back of the boat and whale sharks come around to feed. It is very unique!
