Coral reefs offer some of the best dive experiences, thanks to their abundant marine life, diverse corals and warm water diving opportunities. Whether the reefs are deep or shallow, there is always something new to find. From tiny technicolour sea slugs to huge ocean giants passing by, coral reefs host it all.

Here, the divers at share their 8 of their favourite coral reefs to dive and easy ways you can help protect coral reefs around the world from harm.


1.      Komodo, Indonesia


Komodo is one of the most marine species-rich destinations in the world, offering exceptional Indonesia scuba diving and the chance to see Komodo dragons.

Being listed as a UNESCO World Heritage site, it is no surprise the Komodo National Park has something special to offer divers, including over 1,000 fish species, manta rays, dolphins, eagle rays and abundant reef life.

Go diving there and you can immerse in a world of huge underwater pinnacles busy with schools of fish. There are reliable manta ray cleaning stations, vibrant soft corals and plenty of reef sharks to find.

When you’ve had enough diving, you can visit one of the only pink sand beaches in the world or go walking with Komodo dragons.

You can find Green Fins members in Labuan Bajo Komodo here.

 2.      Wakatobi, Indonesia


A UNESCO Biosphere Reserve, the Wakatobi National Park is a renowned example of successful marine conservation, with thriving reefs photography fans return to time and again.

The islands of Wakatobi, scattered across bright turquoise waters, are perfect for both divers and snorkellers thanks to the abundance of life in the shallows and at depth.

Hawksbill and green sea turtles can be seen at Wakatobi, grazing on shallow seagrass beds and munching on huge reef sponges respectively. Meanwhile, the reefs are busy with swirling schools of pelagic fish and the tiniest critters you can imagine.

This is one of the best destinations in the world for finding pygmy seahorses. You’ll need to look closely though – they’re smaller than your little fingernail!

 3.      Kimbe Bay, Papua New Guinea

Ranked as one of the world’s best coral reefs by National Geographic, Kimbe Bay is a great dive destination far off the tourist trail.

There are over 200 dive sites and flourishing coral reefs untouched by humans. Being sheltered from the open ocean, the corals of Kimbe Bay have reached enormous proportions. Coral bridges covered in sea fans and staghorn corals provide a dramatic backdrop against big schools of barracuda and passing dolphins. You can also dive a well-preserved WWII Mitsubishi Zero fighter plane there.

 4.      Florida Islands, Solomon Islands

The Florida Islands were at the centre of the WWII Guadalcanal campaign, resulting in the seabed being littered with around 1,000 wrecks, including over 600 aircraft. If you can take your eyes off the historical wrecks, there are healthy reefs to explore and unique lava tubes.

The Twin Tunnels dive site has a seamount with two large lava tubes. You can descend into either tube, then exit in a cave on a deep reef wall.

Schools of fish circle this special seamount and the reef on top is healthy; with sea fans, pygmy seahorses and brightly-coloured squat lobsters hiding in barrel sponges.

5.      Tubbataha National Park, Philippines

With over 10,000 hectares of pristine reefs, you’ll be spoilt for choice if you go diving at Tubbataha Reefs Natural Park.

This UNESCO World Heritage site is also a New Seven Wonder of the World, bursting at the seams with marine life. As well as hundreds of coral and fish species, Tubbataha hosts around 13 different whale species, plus mantas and eagle rays.

Only open to divers from March to June each year, it is one to add to your wish list. Don’t miss it.

 6.      Southern Atolls, Maldives


The Maldives is best-known for luxurious liveaboards and endless sunshine, perfect for finding numerous whale sharks and mantas rays among picture-perfect atolls.

For healthy coral reefs and few dive crowds as well, visit the Maldives Southern Atolls. These quiet atolls offer exploratory diving with numerous undiscovered diving gems.

Laamu Atoll has plenty of mantas and grey reef sharks, plus huge schools of fish in the deep channels. You can find colourful coral reefs there at Maamandhoo Giri.

Meemu Atoll is a perfect choice for soft coral fans, offering vivid reefs swathed in soft corals.

If you visit Nilandhe Atoll you’ll also have the chance to see mobula rays, mantas, reef sharks and large schools of tuna in the blue.

7.      Coral Sea, Australia

The UNESCO-listed Great Barrier Reef is enormous and contains a diverse range of diving opportunities at its different reef systems. The trick to finding the best reefs there is knowing where and when to go.

If you head out to the Coral Sea reefs during October, the weather can be a gamble. But if you get lucky, you’ll be rewarded with 60 meters visibility as you admire reefs covered in soft corals.

Bougainville Reef is all about schools of big pelagic fish and exciting wall diving. There are walls plunging to the depths; encrusted in soft corals, whip corals, gorgonian sea fans and black coral trees.

Remote Osprey Reef is another Coral Sea highlight. It is over 60km away from any other reef and its remoteness has allowed life to flourish there.

Make sure you dive Osprey Reef’s North Horn for shark dives with grey reef, silky and silvertip sharks.

8.      Fakarava Atoll, French Polynesia

Dive destinations don’t get much more photogenic than French Polynesia. This sought-after slice of paradise is not only beautiful above water, it offers exciting diving below the surface.

Fakarava Atoll, a UNESCO Biosphere Reserve, is so diverse that some cruises spend their entire itineraries there. The healthy reefs are covered in hard corals and host Fakarava’s main attraction; hundreds of grey reef sharks. This destination is all about diving with ‘walls of sharks’ and drifting along in swift currents at depth.

Depending on the time of year you visit, you can see humpback whales (August to October) or  hammerhead sharks (December to March) in the surrounding waters, as well as dolphins and mantas. Whenever you visit French Polynesia, don’t miss snorkelling with blacktip reef sharks in the warm, shallow lagoons.

Protecting our Coral Reefs

To protect coral reefs around the world, we all need to use sustainable dive practices and do our part for marine conservation - both at home and while travelling:

8 simple steps to save the oceans.png

  • Make sure you dive gear isn’t hanging loose and banging into corals as you dive

  • Practice your buoyancy skills to ensure you don’t accidentally make contact with corals

  • Keep an eye on your depth to ensure your descents are not out of control and don’t result in reef contact

  • Make sure your finning doesn’t damage corals, which can easily happen when capturing that perfect reef photograph or being distracted by passing marine life

  • Wear reef-safe sunscreen to prevent polluting chemicals entering the ocean

  • Minimise your use of plastics to ensure you’re not contributing to plastic pollution; which ultimately affects the marine life of coral reefs

  • Be an ethical consumer, supporting environmentally conscious local producers and initiatives

  • Minimise your carbon footprint by lowering your food miles and choosing public transport

  • Carbon offset whenever you travel
