Belize’s iconic Blue Hole was one of Jacques Cousteau’s favorite dive spots and is surely one of the most famous scuba diving locations. The UNESCO site is a 125m/410ft-deep sinkhole that can even be seen from space. In addition to flourishing marine protected areas along the world’s second-largest barrier reef, Belize is one of the best places in the world to dive with whale sharks.

Red Sea, Egypt

Egypt’s warm, clear waters shelter over 1,500 colorful coral and fish species amid dramatic reefs and walls. Dive resorts and liveaboards offer easy access to many of the Red Sea’s top dive sites, such as Ras Mohammed’s towering pinnacles, Dahab’s sunny shore dives, and the legendary SS Thistlegorm. Further south, Marsa Alam, The Brothers, and the “Deep South” are all revered for unforgettable pelagic encounters.

Meanwhile, other great scuba diving destinations in and around the Red Sea include:


An array of gentle shore dives, shallow wrecks, and teems of vibrant life make the Bahamas a paradise for learners. On the other hand, advanced adventures come in equal measure with deep walls, drop-offs, blue holes, and drift dives. However, what really sets this Caribbean destination apart as one of the best places to scuba dive is the ease of shark diving for every level of diver at hotspots such as Tiger Beach and Bimini.

With nearly 1,200 islands, the Maldives has no shortage of idyllic beaches and turquoise waters to suit all abilities and budgets.

Golden jellies in Jellyfish Lake, one of many wonders of Palau, where you'll also find some of the best diving in the world


Around 80% of Palau’s waters are protected, so it’s unsurprising that its pristine reefs promise some of the best scuba diving in the world. Indeed, divers say they’ve never seen so many sharks at Palau’s top dive sites such as Blue Corner and Ulong Channel, while German Channel’s cleaning station attracts dozens of mantas.

With some of the world’s greatest reef and wreck diving and thousands of marine species to discover, the Great Barrier Reef is especially well known as one of the best places for scuba diving. But Australia’s adventures don’t stop there. On the west coast, Ningaloo Reef is another whale shark hotspot, while kelp forests in the cooler southern regions are home to playful sea lions, breeding cuttlefish, and enchanting leafy seadragons.


Boasting two contrasting coastlines, Mexico is undoubtedly one of the world’s best scuba diving destinations. Firstly, venture east for stunning Caribbean reefs along the Yucatan Peninsula and Cozumel, an ethereal network of cenotes, and even an underwater art museum. Then, on the Pacific side, you’ll find thrilling drift dives, mantas, and migrating humpbacks at Socorro Island, while La Paz’s kelp forests are a playground for divers and sea lions alike.


The Philippines is synonymous with out-of-this-world marine life experiences. Beyond Tubbataha’s abundant reefs, there are thresher sharks in Malapascua, dugongs in Palawan, and whale sharks in Donsol, as well as phenomenal sardine bait balls in Moalboal. For rarer critters, Anilao is undeniably a macro mecca with frogfish, ghost pipefish, blue-ring octopuses, bobtail squid, and hundreds of nudibranchs. Then, if you’ve had your fauna fix, head to Coron Bay’s wrecks to rediscover WWII history.

Galapagos Islands, Ecuador

A staple of most divers’ bucket lists, the Galapagos’ remote and unique ecosystem is nurtured by strong currents that rush across the volcanic seascape. Here you’ll meet schooling hammerheads, molas, and mantas, alongside several endemic species, such as marine iguanas, Galapagos penguins, and red-lipped batfish. Although sought-after sites like Darwin and Wolf Island are reserved for experienced divers, there are still plenty of sheltered coves where beginners can behold this wonderland.

UK and Ireland

The UK and Ireland are often overlooked when considering destinations with the best scuba diving, but these bountiful, cold waters might surprise you. Alongside thousands of shipwrecks (including world-class Scapa Flow), the medley of marine life is equally impressive, from tiny tompots to dolphins, whales, and giant basking sharks—not to mention frolicsome, fin-nibbling seals!

Hawaii, USA

Hawaii’s lush, volcanic islands are marked by high-rising cliffs, lava tubes, sea caves, craters, coral reefs, and even wrecksmany easily reached during some of the best shore diving in the world. As well as whale migrations, look out for turtles, hammerheads, Hawaiian monk seals, and the dazzling dragon moray eel.

Malaysia’s calm waters lay claim to some of the planet’s best-preserved reefs—from Perhentian Island’s shallow-yet-prolific coral gardens to Borneo’s sea fan forests. Specialties are well catered for, too; deep divers will delight in Layang Layang’s walls, while Mabul is a macro haven. However, Malaysia’s crown jewel is Sipadan, where you’ll find turtle after turtle and one of the best dive sites in the world.
