Best for · Ultimate shore diving freedom, macro biodiversity & self-guided dive trucksOver 60 marked roadside yellow stones offer complete dive autonomy. Rent a double-cab pickup truck, swap tanks at drive-thru stations, and walk directly into warm Caribbean drop-offs with zero boat charters required.
In 95% of international dive destinations, your underwater time is strictly dictated by dive boat rosters: 08:00 AM harbour roll calls, strict 45-minute dive time limits enforced by guides, and £60–£120 daily boat surcharges.
Bonaire reverses this dynamic completely.
Along the leeward western coastline, over 60 premier dive sites are marked by yellow-painted roadside stones sitting right on the coastal asphalt. You rent a double-cab pickup truck, load four to six cylinders into the rear truck bed, drive to a site, park on the coral verge, and walk straight into the Caribbean Sea.
Bonaire’s shoreline is composed of ancient fossilized coral limestone known locally as ironshore. It is jagged, honeycombed, and often slippery.
Bonaire is exceptionally welcoming to Open Water novices, but advanced sites demand disciplined navigation and gas management:
Bonaire consistently ranks #1 in the Tropical Western Atlantic for marine biodiversity according to data collected by REEF volunteer surveys:

Best for · Colossal coral biodiversity, outer reef liveaboards & giant potato cod encountersThe official gateway to the world's largest coral reef system. Skip crowded inner day-boats: choose dedicated 3-day outer reef liveaboards or Coral Sea expeditions to experience 40m visibility and giant potato cod.
The Great Barrier Reef spans over 2,300 kilometres along the Queensland coast. Cairns is its commercial epicenter.
However, thousands of international divers leave Cairns disappointed because they book the wrong trip:
The northern Ribbon Reefs feature two of the most celebrated dive sites on the planet:

Best for · World-class drift diving, sheer coral drop-offs & flying over pristine reefsLocated off Mexico's Yucatan Peninsula, Cozumel is the planet's premier drift diving arena. Fast oceanic currents sweep you past vertical walls, giant barrel sponges, and underwater caverns with effortless neutral buoyancy.
Cozumel sits directly in the path of the Yucatan Current, a powerful oceanic conveyor belt surging northward between the island and mainland Mexico into the Gulf of Mexico.
Because of this constant hydrographic highway, diving in Cozumel feels like effortless flight. You do not fin forward; you simply drop to your desired depth, establish crisp neutral buoyancy, cross your arms or let them stream at your sides, and let the 1 to 3 knot current glide you past miles of living reef. The boat captain tracks the dive group’s bubbles from the surface and collects you the moment you pop up.
Cozumel’s underwater topography is breathtaking, but the sheer drop-offs require unwavering depth discipline:
Cozumel’s isolated insular platform supports distinctive Caribbean species found virtually nowhere else:
How2Scuba operates with zero commercial kickbacks. When arranging your dives, consider these respected local operations based in San Miguel:
Best for · Legendary artificial wreck trekking & shallow sunlit spur-and-groove coral reefsStretching 120 miles along the Overseas Highway, the Florida Keys offer two starkly different worlds: sunlit shallow coral gardens at 6–9m, and colossal deep military shipwrecks like the Spiegel Grove and Vandenberg.
The Florida Keys barrier reef tract is the only living coral barrier reef in the continental United States. It stretches over 120 miles parallel to the Overseas Highway (US-1), from Key Largo down to Key West.
To understand diving here, you must recognize that the Keys consist of two completely distinct underwater environments:
Many recreational divers treat artificial reefs casually, but the outer Keys wrecks demand strict technical discipline:
Inside the Florida Keys National Marine Sanctuary (FKNMS), coral formations run perpendicular to the shoreline in long coral fingers known as spurs, separated by white sand channels known as grooves:

Best for · Guaranteed sea turtle encounters, thrilling Indonesian drift dives & laid-back island livingThree tiny coral fringed islands nestled off northwest Lombok. Free from motorized vehicles, the Gilis offer world-famous sea turtle sanctuaries, oceanic seamounts, and exhilarating drift dives fueled by the Indonesian Throughflow.
Lying just off the northwest coast of Lombok, Indonesia, the three Gili Islands (Gili Trawangan, Gili Meno, and Gili Air) form a tranquil, car-free scuba sanctuary.
Motorized transport is banned across all three islands; transport is conducted exclusively on foot, by rented bicycle, or via traditional horse-drawn carts (cidomo). However, each island has a completely distinct personality:
The Gili Islands sit right on the edge of the Lombok Strait, one of the planet’s major oceanic choke points:
The Gilis are globally famous for their exceptionally dense resident sea turtle population:

Best for · World-class historic wrecks, vibrant coral pinnacles & exceptional value day-boatsJust 5 hours from Europe with direct budget flights, Hurghada is the gateway to the northern Red Sea. Purpose-built day-boats offer 2 to 3 daily dives with hot buffet lunches, historic WWII wrecks, and pristine fringing reefs.
For divers based in the UK and Europe, Hurghada offers the highest return on investment in global diving.
A direct flight on easyJet, Wizz Air, or Pegasus costs £120–£250 return. Once in Hurghada, full-day dive boat charters cost just £40–£60 per day—and unlike Caribbean or Mediterranean day-boats where you are returned to dock between dives, Red Sea operations use custom 25-to-35 metre wooden motor yachts.
While Hurghada’s coastal house reefs (such as Fanadir and Abu Ramada) are tranquil and sheltered, the northern offshore wrecks in the Strait of Gubal require serious preparation:
Under the regulations enforced by the Chamber of Diving & Watersports (CDWS):
The Red Sea features a 14%+ endemism rate among reef fish due to its geological isolation:

Best for · World-class course affordability, granite pinnacles & whale shark encountersNestled in the Gulf of Thailand, Koh Tao is the world's most famous certification hub. Granite pinnacles rise from 35m depths, surrounded by warm tropical water, whale sharks, and vibrant coral nurseries.
Covering just 21 square kilometres in the Gulf of Thailand, Koh Tao is the undisputed global hub for entry-level and continuing dive education.
The island’s economic setup is legendary: an all-inclusive PADI or SSI Open Water course costs approximately £250–£320 (11,000–13,000 THB), frequently including basic fan-room accommodation.
However, Koh Tao is not just a budget classroom for beginners. Its offshore deep granite pinnacles—specifically Chumphon Pinnacle, Southwest Pinnacle, and Sail Rock—rank among Southeast Asia’s most thrilling pelagic aggregation sites.
To have an exceptional experience on Koh Tao, choosing the right base is critical:
Koh Tao operations run on converted traditional wooden Gulf of Thailand boats:
Koh Tao’s granite boulders provide stunning topography, but divers must understand local nuances:
Koh Tao is world-renowned for wild encounters with the world’s largest fish:

Best for · Best shore and beach dives close to the UKJust 4 hours from the UK with zero boat charter fees. Playa Chica in Puerto del Carmen offers Europe's finest walk-in beach diving: volcanic tunnels, 30m drop-offs, winter angel sharks, and resident dusky groupers.
For UK and northern European divers, Lanzarote is the undisputed king of affordable, high-quality diving.
In the UK, a weekend of diving often means a 3-hour motorway drive, £90–£120 per day for a hard-boat charter that gets cancelled 50% of the time due to rough swell, £1,000+ invested in a drysuit and undersuits, and fighting through 2–4 metres of murky visibility.
In Lanzarote, you can catch a £50–£120 direct flight from Gatwick, Manchester, Birmingham, Bristol, or Edinburgh on budget carriers (Ryanair, easyJet, Jet2). Within four hours, you touch down in 22°C sunshine, check into an affordable self-catering apartment in Puerto del Carmen, and walk directly into 25-metre volcanic visibility in a 5mm or 7mm wetsuit.
Playa Chica is a small volcanic cove located on the edge of Puerto del Carmen’s Old Town harbour. Despite measuring less than 100 metres across, it is the launching pad for over 10 distinct, world-class dive routes.
As soon as you descend into the bay, you swim over a clean sand bowl (6–10m depth) surrounded by volcanic rock ledges. Proceeding seaward, the bottom shelves off down a sandy slope to 18 metres, where a dramatic cliff line drops away into the Atlantic abyss (dropping past 45m).
A critical safety principle that many commercial travel sites ignore is that divers have strict depth limits according to their certification level.
At sites like the Blue Hole (Agujero Azul):
Always dive within your certified limits and carry an active dive computer to track your no-decompression limits (NDL).
Lanzarote sits in a biological transition zone where Mediterranean, Atlantic, and subtropical species meet:
How2Scuba has no commercial affiliation with dive centres and does not take booking commissions. When diving in Lanzarote, you can deal directly with well-established local operators who have bases right on or adjacent to Playa Chica:
Best for · Dramatic volcanic basalt architecture, deep wrecks & giant Atlantic stingraysFour hours from Europe with year-round subtropical sunshine, Tenerife offers volcanic underwater drama. Explore basalt organ pipe columns, the Tabaiba shipwreck, and sand arenas filled with giant Atlantic stingrays.
Located in the mid-Atlantic off the coast of Western Sahara, Tenerife offers consistent subtropical diving when mainland Europe is frozen.
A direct flight from London, Dublin, Paris, or Frankfurt takes just 4 hours and 15 minutes. With daily high temperatures averaging 21–28°C all year round, divers can escape winter gloom, rent an affordable car, and dive dramatic volcanic drop-offs without crossing multiple time zones.
To plan your diving effectively, understand the physical separation between Tenerife’s two main sectors:
The Canary Islands sit at an evolutionary crossroads between temperate Atlantic and tropical African ecosystems:

Best for · Playful Atlantic grey seal encounters, historic naval shipwrecks & world-class temperate divingRugged, historic, and biologically rich. The UK offers some of the world's finest temperate diving: friendly grey seals in the Farne Islands, the sunken German WWI battlefleet in Scapa Flow, and iconic South Coast wrecks.
UK diving is often dismissed by holiday divers as cold and murky. That reputation is deeply undeserved.
When you learn to dive in British waters, you gain skills in buoyancy, compass navigation, and thermal management that make tropical diving feel effortless. From the curious juvenile Atlantic grey seals of the Farne Islands to the colossal German WWI High Seas Fleet in Scapa Flow, the UK offers encounters you cannot replicate anywhere else on Earth.
Located off the coast of Northumberland in northeastern England, the Farne Islands are home to over 5,000 Atlantic grey seals (Halichoerus grypus):
In June 1919, Rear Admiral Ludwig von Reuter scuttled the entire interned German Imperial Navy fleet of 74 warships in Scapa Flow, Orkney:

Best for · Ultra-affordable Caribbean certifications, seamounts & seasonal whale shark spottingThe smallest of Honduras' Bay Islands, Utila is a legendary Caribbean budget haven. Dive submerged seamounts like Black Hills, drift down vertical northern drop-offs, and enjoy free accommodation bundled with dive courses.
Perched at the southern tip of the Mesoamerican Barrier Reef System (the second-largest barrier reef on Earth), Utila is the Caribbean’s undisputed budget diving paradise.
Measuring just 11 kilometres long, the island is blissfully free from commercial resort chains, traffic jams, and mega-cruises. Transport is conducted entirely on foot, on bicycles, or via three-wheeled motorized tuk-tuks rattling along the single main street of Eastern Harbour.
To understand Utila’s diving landscape, consider its two distinct coastlines:
Utila is widely recognized as one of the few places in the Caribbean with year-round resident whale sharks (Rhincodon typus):

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.
Lanzarote and Tenerife in the Canary Islands are direct 4-hour flights from most UK regional airports (Gatwick, Manchester, Bristol, Edinburgh) with low-cost airfares and year-round diving. Lanzarote (especially Playa Chica in Puerto del Carmen) is the standout choice for shore diving, where you can walk straight into clear volcanic water without paying for expensive daily boat charters.
Match the destination to your budget, how warm you want the water to be, and what marine life you want to see — the comparison table on this page is built around exactly those factors.
