The shore diving capital of the world. Calm, protected waters and over 60 accessible dive sites right off the beach.

Often hailed as the shore diving capital of the world, Bonaire offers unparalleled freedom. Unlike other destinations where your day is strictly dictated by boat schedules, Bonaire operates on “drive and dive” logistics. You simply load your rental truck with tanks, drive up to a yellow stone marking a dive site along the coastal road, and walk into the water.
This independence is perfect for photographers who want to spend 90 minutes macro-hunting at a single site without worrying about a group, or buddy pairs who want to dive on their own schedule.
The entire island is surrounded by a protected marine park, meaning the fringing reef starts just a few meters off the shore. You wade in, kick out for a minute, and the reef drops off.
Bonaire isn’t the place for massive pelagics. You are unlikely to see sharks or manta rays. Instead, it is a macro and reef fish paradise. Expect massive schools of tarpon hunting at night, ubiquitous sea turtles, seahorses hiding in gorgonians, and pristine coral structures.
Bonaire is a quiet, arid island. It is technically a special municipality of the Netherlands, giving the main town of Kralendijk a distinctly European feel with excellent (if slightly expensive) dining. If you want wild nightlife, go elsewhere. If you want a peaceful evening recounting the day’s dives over a good steak, Bonaire is perfect.

The bucket-list answer. A liveaboard out of Cairns reaches the outer reef's clearer water and bigger marine life — worth the extra travel budget at least once.

Cairns is the primary gateway to the Great Barrier Reef (GBR), the largest living structure on Earth. While the inner reefs closest to Cairns suffer from heavy day-tripper traffic, Cairns is also the departure point for the iconic liveaboards that head out to the Ribbon Reefs and the Coral Sea.
The GBR offers everything from shallow coral gardens to dramatic drop-offs.
The biodiversity is staggering. You can expect to see everything from tiny nudibranchs to massive Minke whales (if you visit between June and July). Six of the world’s seven species of sea turtles can be found here, alongside reef sharks, giant groupers, and thousands of species of reef fish.
Cairns is a bustling tropical tourist hub. The Esplanade is packed with bars, restaurants, and a massive public lagoon. It is also the jumping-off point for exploring the Daintree Rainforest, meaning you can easily combine world-class diving with terrestrial jungle adventures.

Marine-park-protected walls with some of the best visibility in the Caribbean. Currents do the swimming for you, which makes drift diving here surprisingly beginner-friendly.

Cozumel is synonymous with drift diving. Located off the eastern coast of Mexico’s Yucatan Peninsula, this island sits squarely in the path of a constant oceanic current. You simply drop in, let the current carry you over the reef, and the boat picks you up when you surface.
Diving here feels like flying. You expend very little energy as the ocean does all the work.
The reefs are incredibly healthy, adorned with massive barrel sponges and sea fans. Keep an eye out for the endemic Splendid Toadfish, which is found nowhere else on earth. Nurse sharks, eagle rays, and massive loggerhead turtles are also extremely common sights.
While heavily developed with all-inclusive resorts and a bustling cruise ship port, Cozumel still retains a laid-back Caribbean charm if you venture away from the main strip in San Miguel. It’s an easy, reliable, and highly comfortable destination for North American and European divers alike.

A string of tropical islands stretching off the southern tip of Florida, home to the Florida Reef Tract and monumental artificial wrecks.

The Florida Keys offer the only living coral barrier reef in the continental United States. However, what really puts the Keys on the map for advanced divers is its incredible “Wreck Trek”—a series of massive, intentionally sunk ships that have become thriving artificial reefs.
The diving here caters to two distinct extremes:
The artificial reefs attract massive schools of barracuda, Goliath groupers (which can weigh over 300kg), and various reef sharks. The shallow reefs are home to nurse sharks, stingrays, and typical Caribbean reef fish.
The Keys stretch over 100 miles, connected by the spectacular Overseas Highway. The vibe gets progressively more eccentric as you drive south, culminating in the wonderfully weird Key West. Expect excellent seafood, tiki bars, and a heavily maritime-focused culture.

A short boat ride from Bali or Lombok, the three Gili Islands (Trawangan, Meno, and Air) offer car-free living and arguably the highest concentration of green sea turtles in Southeast Asia. Currents can pick up slightly compared to Koh Tao, offering a gentle introduction to drift diving.

Located just off the northwest coast of Lombok (and a fast boat ride from Bali), the Gili Islands are a backpacker haven. Gili Trawangan (Gili T) is the largest and most developed, while Gili Air and Gili Meno offer quieter alternatives. The diving here is incredibly easy, making it one of the most popular places in Indonesia to get certified.
The Gilis are basically a massive sandbox for divers. The water is bath-warm (29°C year-round) and the sites are mostly sloping coral reefs with sandy bottoms.
If you want to see turtles, this is the place. It is almost impossible to dive the Gilis without seeing green and hawksbill turtles—sometimes half a dozen on a single dive. Reef sharks are common at sites like Shark Point, and macro lovers will find plenty of nudibranchs and ghost pipefish.
The Gilis are famous for having no motorized transport. You get around by bicycle, horse-drawn cart (cidomo), or walking. Gili T is infamous for its wild, full-moon-style beach parties, while Gili Air is a more mature yoga-and-diving retreat.

A direct 5-hour flight from most of Europe into some of the Red Sea's most reliable reefs — a strong pick if your holiday time is limited but your ambitions aren't.

Hurghada is the gateway to the Egyptian Red Sea, offering arguably the best “bang for your buck” diving in the world. For Europeans, it’s a short flight to access world-class wrecks, stunning visibility, and dramatic coral walls at a fraction of the price of the Caribbean.
Hurghada operates primarily via daily boat diving, though it is also the departure point for the famous Northern Red Sea liveaboards.
The Red Sea is remarkably saline, which creates brilliant visibility. The reefs are incredibly vibrant. Keep an eye out for blue-spotted ribbontail rays, massive moray eels, and the occasional pod of spinner dolphins.
Hurghada is a massive, sprawling resort town. It lacks the laid-back charm of places like Dahab, but it makes up for it in sheer convenience. You will find massive all-inclusive resorts, expansive marinas, and all the tourist infrastructure you could ever need.

Known globally as the 'factory' of diving. High competition between centres keeps prices the lowest in the world, while the sheer volume of instructors means teaching standards are generally kept sharp. The diving is extremely easy: zero current, warm water, and shallow sites perfect for Open Water skills.

While the reefs here aren’t quite as pristine as the Maldives or Raja Ampat, it remains the undisputed champion of the budget diving world. If you want to get certified on the cheap, meet hundreds of other travellers, and enjoy a vibrant nightlife after your dives, Koh Tao is the place to be.
Koh Tao translates to “Turtle Island”, and it lives up to its name. But more than turtles, this island is famous for being a diver-making factory. Because the island’s entire economy is structured around scuba diving, the logistics are incredibly refined. Dive boats are large and comfortable, equipment is replaced frequently, and the competition between dive centres keeps prices aggressively low.
Beyond the cost, the diving itself is remarkably forgiving. The Gulf of Thailand is shielded from major ocean currents, meaning you rarely experience the “washing machine” drift dives you might find in Indonesia. The water is consistently bath-warm (29°C), meaning you only need a thin shorty wetsuit, or even just a rash guard.
Diving in Koh Tao is characterized by massive granite pinnacles that rise from the sandy seabed. These underwater mountains create a thriving ecosystem.
Koh Tao is one of the few places in the world where you have a legitimate, albeit unpredictable, chance of seeing a Whale Shark. They are most commonly spotted around Chumphon Pinnacle and Sail Rock between March and May, though sightings happen year-round. Unlike places where you snorkel with them, in Koh Tao, they often cruise right through the middle of the dive group.
The island is tiny but deeply vibrant. The main strip, Sairee Beach, is lined with beach bars, fire dancers, and restaurants. It is a backpacker’s paradise. If you want a quieter experience, the southern end of the island (Chalok Baan Kao) offers a more relaxed, family-friendly vibe.
Expect to rent a scooter to get around, but be warned: the roads can be treacherous, and “Koh Tao tattoos” (scooter exhaust burns or scrapes) are an island cliché for a reason.

Four hours from most UK airports with volcanic rock formations, swim-throughs and resident turtles — cooler water than the tropics, so pack a 5mm wetsuit.

Tenerife offers the most dramatic, volcanic underwater topography in Europe. It is the perfect year-round destination for European divers who want warm-ish water and excellent visibility without enduring a long-haul flight.
The diving in the Canary Islands is defined by what the volcanoes left behind.
While it lacks the colourful soft corals of the tropics, Tenerife has its own unique ecosystem. It is one of the best places in Europe to see Angel Sharks (especially in winter) and massive, graceful butterfly rays. Huge schools of barracuda, stingrays, and octopus are everyday sights.
Tenerife is incredibly diverse. The south is dominated by large tourist resorts and year-round sunshine, while the north is lush, green, and culturally rich. Between dives, you can hike the volcanic landscapes of Mount Teide or enjoy world-class Spanish tapas.

Challenging but rewarding cold water diving, featuring world-class wrecks and playful grey seals.
Hero image credit: Unsplash
It is often said that if you can dive in the UK, you can dive anywhere in the world. UK diving is challenging, cold, and heavily reliant on tides and weather. However, for those willing to brave the drysuit, the UK offers some of the most historic and world-class wreck diving on the planet—especially along the rugged coastline of Southwest England.
The Southwest of England is arguably Britain’s richest diving region:
The UK coast is a graveyard for thousands of ships. In terms of marine life, the Southwest UK boasts playful grey seals, massive conger eels hiding in wrecks, cuttlefish breeding in spring, and surprisingly colourful cold-water reefs covered in plumose and jewel anemones.
UK dive trips usually end in the pub. It is a hearty, resilient culture where bad weather is expected and good visibility is celebrated like a lottery win. The camaraderie on a UK dive boat is unmatched.

The Caribbean's answer to Koh Tao — a backpacker island where certification is cheap, and it happens to sit on one of the most reliable whale shark migration paths in the world.
Hero image credit: Unsplash
Utila is the Caribbean’s answer to Koh Tao. It is a tiny island in the Bay Islands of Honduras that has built its entire identity around budget backpacker diving. It is cheap, relaxed, and world-renowned as a hotspot for spotting Whale Sharks.
The diving here is laid-back and easy, perfect for ticking off your Open Water or Advanced certifications.
Utila is famous as the “Whale Shark Capital of the Caribbean”. While sightings are never guaranteed, they are most common between March and April, and August and October. Beyond the big fish, you can expect classic Caribbean marine life: eagle rays, nurse sharks, and massive schools of Creole wrasse.
Utila is proudly unpolished. There are no massive all-inclusive resorts here—just cheap hostels, dive centre dorms, and over-the-water bars. The island is tiny (you can walk almost everywhere) and the nightlife is legendary. It is the perfect place to drop off the map for a month and emerge as a Divemaster.

No destination on this page paid for placement. Ranking is based on four weighted factors, checked against operator data and our own trip notes.
Current, depth and entry style — how much margin for error a first-time diver actually gets.
Multi-year averages, not a single good week someone happened to photograph.
Course price plus accommodation and flights, benchmarked in relative tiers.
Instructor ratios, safety record and equipment condition, from our recommended centres list.
Koh Tao in Thailand is consistently the cheapest place to get Open Water certified, thanks to high instructor competition and low cost of living. Utila in Honduras is a close second for the Caribbean side.
Gili Islands in Indonesia and Bonaire in the Caribbean are both excellent for beginners because of calm, shallow reefs, minimal current, and strong visibility most of the year.
No. All eight destinations in this guide have well-regarded dive centres that can take you from zero experience through to Open Water certification on-site.
Tenerife in the Canary Islands is the shortest flight from the UK with reliable year-round diving, though water is cooler than tropical destinations, so a thicker wetsuit is worth packing.
