Isla del Coco, Costa Rica
Five hundred and fifty-five kilometers off the coast of Costa Rica lies Isla del Coco, an island Jacques Cousteau described as “the most beautiful island in the world.” Isla del Coco was declared a World Heritage Site in 1994 and is home to one of the largest congregations of scalloped hammerhead sharks, along with large populations of white tipped reef sharks, Galapagos sharks, and silky, silver, tiger, and black tip sharks. The only way to dive and explore this mystical place is via a live aboard dive boat.
Isla Guadalupe, Mexico
Isla Guadalupe is one of the best great white shark cage diving destinations. Aside from being a temporary home to around 17o great white sharks between July and November, the great white sharks that come to this island are some of the largest recorded on the planet. The visibility is usually quite good, which plays a significant part in the quality of the dive site. It is a bit of a trek to get here, but that journey is well worth it for the great white shark encounters that you are sure to have.
Isla Mujeres, Mexico
Isla Mujeres is located in the Gulf of Mexico on the Caribbean side. It is home to the largest population of whale sharks between June and Septembers. Hundreds of whale sharks make their way to this island to feast on the massive plankton blooms. Some claim that Isla Mujeres is one of the best places in the world to dive with these gentle giants.
Tiger Beach, Grand Bahama Island
Tiger Beach is one of the most famous tiger shark dive spots. While you can see tiger sharks here almost any time of the year, the best time to visit is between October and January when they congregate for the breeding season. These massive beauties cruise the sandy bottoms at depths of only 7 meters/20 feet. The crystal clear shallow water makes for an incredible setting to spend time with these impressive predators.
Beqa Lagoon, Fiji
Beqa Lagoon is home to the Shark Reef Marine Reserve. The Fijians realized that sharks are far more valuable when alive for two reasons; one, they are at the top of the food chain and without them that chain would collapse and the local fisheries would greatly suffer and two, they bring in a lot of money from shark tourism. This reserve is home to eight main shark species, including the most famous, the bull shark. There are more than 20 dive sites within the lagoon and shark enthusiasts can easily spend a week diving here and look forward to seeing sharks on every single dive.
Rangiroa, French Polynesia
Rangiroa is home to an astonishingly vibrant and thriving reef. There are two passes through the reef where twice a day the tide change and nutrients flood in and attract a large gathering of pelagic fish, including sharks. The visibility is incredible and on good days it can be clear down to 60 meters/200 feet. Divers have reported seeing upwards of 100 sharks on a single dive. Black tip, white tip, grey, and silver tip sharks are the most common visitors, but the great hammerhead shark shows up between December and March.
The waters around the micro-sized island of Malapascua are surprisingly home to the rarely seen thresher shark. This unique and strange looking shark has a whip-like tail that is as long as its body. At around 30 meters, the Malapascua shoal is where you are most likely to spot this incredible shark. Aside from the opportunity to dive with such an elusive species, the setting beneath and above the water is breathtakingly beautiful.
Aliwal Shoal, South Africa
The Aliwal shoal is a reef formation that attracts large numbers and diverse species of sharks on a regular basis.

The best conditions are typically between March and July, but shark diving is possible all year around.
