Let’s gear up and dive in.

1. Raja Ampat, Indonesia

Set deep within the Coral Triangle, where the Pacific and Indian Oceans meet, Raja Ampat is one of the most biodiverse dive destinations on Earth. This remote Indonesian archipelago — made up of over 1,500 jungle-covered islands — is a dreamscape for divers, with vibrant coral gardens, steep drop-offs, and pelagic-rich currents. The region holds the world record for the most species recorded in a single dive and feels utterly untouched thanks to its remoteness. Diving here is like swimming through an underwater kaleidoscope — expect glassy waters, jaw-dropping visibility, and mind-blowing marine life on every descent.

2. Great Barrier Reef, Australia

Stretching over 2,300 kilometres along Queensland’s coastline, the Great Barrier Reef is the largest coral reef system on Earth — so vast it’s visible from space. It’s a legendary diving destination, not just for its size, but for its sheer variety of dive environments: colourful coral gardens, dramatic drop-offs, vibrant bommies, and the occasional sandbar-turned-island. The northern Ribbon Reefs and the remote Coral Sea sites offer some of the clearest water and most exhilarating dives in the region. And then there’s the SS Yongala — arguably one of the best wreck dives in the world. Whether you’re new to diving or chasing bucket-list experiences, the GBR has something to offer.

3. Red Sea, Egypt

The Red Sea has long been a favourite among European divers — and with good reason. Just a short flight from much of Europe, it offers clear, warm waters, thriving coral reefs, dramatic walls, and some of the most accessible wreck diving on the planet. The northern coast around Sharm El Sheikh and Dahab features vibrant reefs and famed sites like the Thistlegorm, a British WWII cargo ship turned underwater museum. Head south to Marsa Alam and the Brothers Islands for deep walls, shark encounters, and fewer crowds. The Red Sea’s unique mix of accessibility, affordability, and world-class diving makes it a standout for divers of all experience levels.

Remote, rugged, and raw — the Galápagos Islands offer some of the most exhilarating diving on the planet. Located 1,000 km off the coast of Ecuador, this volcanic archipelago is a haven for big animal encounters, strong currents, and breathtaking underwater drama. Diving here isn’t about coral gardens or macro critters — it’s about watching entire schools of hammerheads sweep past in formation, spotting massive whale sharks in the blue, and sharing the water with curious sea lions. The currents can be wild, and water temperatures fluctuate, but the payoff is next-level. This is truly bucket-list diving for those who live for adrenaline and awe.

5. Silfra Fissure, Iceland

If you’ve ever dreamt of diving between continents, Silfra is where that dream becomes reality. Tucked within Iceland’s Þingvellir National Park, this glacial fissure is the only place in the world where you can dive directly between the North American and Eurasian tectonic plates. The water here is pure glacial melt, filtered through volcanic rock for decades, resulting in unmatched visibility — often over 100 metres. While Silfra lacks the vibrant marine life of tropical sites, the surreal topography and crystal-clear water make it an unforgettable dive. It’s chilly, yes — but totally worth the dry suit.

• Top dive sites: Silfra itself is the main (and only) site, split into four sections: Big Crack, Silfra Hall, Silfra Cathedral, and Silfra Lagoon

• Best time to go: June to September for slightly warmer surface temps and easier access

  • Water clarity: 100m+ visibility — the clearest diving on Earth

  • Marine life: Minimal — the dive is about geology and clarity, not coral or fish

  • Coral & Wrecks: None — this is a freshwater, glacial environment

6. Sipadan, Malaysia

Rising dramatically from the depths of the Celebes Sea, Sipadan is Malaysia’s only oceanic island — a limestone pinnacle formed by living coral over thousands of years. What makes Sipadan legendary among divers is the sheer abundance and density of marine life. This is one of the few places where you can descend into a swirling vortex of barracuda, glide past giant turtles, and spot reef sharks cruising over vibrant drop-offs — all on a single dive. The island itself is protected, with only a limited number of daily dive permits issued to preserve its fragile ecosystem. It’s wild, alive, and a must for any serious diver’s bucket list.

8. Palau, Micronesia

Tucked away in the western Pacific, Palau is a remote island nation known for dramatic drop-offs, pristine reefs, WWII wrecks, and one of the most iconic dives on the planet — Blue Corner. What sets Palau apart is its mind-blowing diversity: in a single trip you can dive with sharks, drift along walls teeming with reef life, explore historic wrecks, and even float through a lake filled with non-stinging jellyfish. Strong currents in some areas mean epic pelagic sightings, and the protected status of much of Palau’s waters ensures healthy, vibrant reefs.

This tiny island in the southern Caribbean offers over 80 marked dive sites, many of which you can access straight from the beach. Just pull up in your rental truck, gear up, and wade in. The reef starts close to shore, currents are generally mild, and the marine park protection has kept the coral in incredible condition for decades. Combine that with 30m+ visibility, chilled island vibes, and dive-as-you-please freedom, and you’ve got the perfect setup for laid-back underwater exploration.

You won’t find sprawling coral gardens here — instead, expect underwater cliffs, lava caves, and towering pinnacles teeming with marine life.
