Understanding Sea Turtles
Sea turtles are ancient reptiles that have navigated Earth’s oceans for more than 100 million years. Of the seven recognized species of marine turtles, five are frequently encountered by recreational divers:
- Green Sea Turtle (Chelonia mydas): The most common turtle on tropical reefs, named for the green color of their fat rather than their shells. Adults are strictly herbivorous, feeding on algae and seagrass beds in shallow water.
- Hawksbill Turtle (Eretmochelys imbricata): Recognizable by their pointed, hawk-like beak and jagged shell margins. They play a vital role in reef health by feeding almost exclusively on sea sponges.
- Loggerhead Turtle (Caretta caretta): Characterized by a massive head and powerful jaws designed for crushing hard-shelled prey like crabs and conchs.
- Olive Ridley & Kemp’s Ridley: Smaller, rounded turtles known for their synchronized mass-nesting events (arribadas).
- Leatherback Turtle (Dermochelys coriacea): The largest turtle on Earth (reaching up to 2m in length), pelagic and rarely seen on shallow reefs.
Top Destinations & Dive Sites for Turtle Encounters
- Turtle Heaven & Shark Point (Gili Islands): The undisputed green turtle capital of Southeast Asia—divers routinely count 15 to 20 individuals on a single dive.
- Palancar Reef & Columbia Reef (Cozumel, Mexico): Resident hawksbills and giant loggerheads drifting effortlessly along vibrant vertical coral walls.
- Salt Pier & 1000 Steps (Bonaire): Shallow seagrass beds in the Dutch Caribbean filled with foraging juvenile green turtles.
- El Puertito (Tenerife): A sheltered natural volcanic bay famous for resident friendly green turtles.
- Flynn Reef & Norman Reef (Cairns / Great Barrier Reef): Six of the world’s seven sea turtle species inhabit the outer Great Barrier Reef cays.
Diver Etiquette & Protection Rules
Sea turtles are air-breathing reptiles that must regularly swim to the surface for oxygen:
- Never Block Surface Access: Never hover directly over a turtle. If it feels boxed in when it needs to breathe, it can panic and drown.
- Never Touch or Ride: Touching stresses turtles, strips protective shell coatings, and is strictly illegal in marine parks worldwide.
- Keep Minimum 2–3m Distance: Give the turtle space to graze and rest on the coral without crowding.

Why Dive in Bonaire?
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.
PADI & SSI Training Routes on Bonaire
Bonaire’s calm, surge-free leeward coastline makes it one of the world’s finest training grounds for both entry-level and advanced certifications:
- Open Water Course (Dives 1 & 2 · 6–12m): Conducted at ultra-sheltered house reefs such as Bari Reef (Sand Dollar/Den Laman) or Something Special (Kralendijk harbour), featuring sandy bottoms for skill demonstrations without risk to fragile corals.
- Open Water Course (Dives 3 & 4 · 12–18m): Progressing onto Salt Pier or 1000 Steps, introducing multi-level shore entries, surface compass navigation, and fish identification.
- Advanced Open Water (Adventure Dives · 18–30m):
- Deep Dive: Hilma Hooker (28–30m) or Karpata (30m) to practice depth gauge verification and nitrogen narcosis awareness.
- Underwater Navigation: Angel City utilizing the double-reef sand channel for reciprocal compass courses.
- Night Dive: Bari Reef or Something Special for close encounters with hunting tarpons and bioluminescence.
Local Dive Centre Intel & Operations
Because diving in Bonaire is 90% shore-based, local dive centres operate specialized “drive-thru” tank exchange stations:
- Dive Friends Bonaire: Multiple retail and tank pickup locations across Kralendijk, Hamlet Oasis, Yellow Submarine, and Port Bonaire. Excellent for divers wanting unlimited air/nitrox pickups anywhere on the island.
- Buddy Dive Resort: World-famous 2-lane drive-thru tank pickup station, on-site boat fleet for Klein Bonaire excursions, and comprehensive PADI CDC instructor development programs.
- VIP Diving: Small-group personalized guiding and private instructor training focused on marine ecology and pristine buoyancy skills.
- STINAPA Nature Fee: All divers must purchase the mandatory STINAPA Marine Park E-Tag ($40/year) before entering the water, which directly funds marine preservation and mooring maintenance.
The Diving Experience
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.
- Shore Diving Logistics: While it sounds easy, entering over rocky ironshore can be tricky. Hard-soled dive boots are absolutely essential here.
- Conditions: The leeward side of the island (where almost all diving takes place) is protected from the trade winds. Expect incredibly calm surface conditions and essentially zero current.
Marine Life Highlights
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.
Above the Surface
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.
Best for · The iconic reef tripCairns / GBR

- GBRMPA Environmental Management Charge (EMC): An official marine park conservation fee of ~$8 AUD per day is collected to support reef management and crown-of-thorns starfish control.
The Diving Experience
The GBR offers everything from shallow coral gardens to dramatic drop-offs.
- Day Boats: These cater heavily to introductory divers and snorkelers. If you are certified, ensure you book a dedicated dive boat rather than a massive tourist vessel.
- Liveaboards: This is where the magic happens. A multi-day trip allows you to escape the crowds and visit world-class sites like the Cod Hole (famous for massive, friendly Potato Cod) and Steve’s Bommie.
Marine Life Highlights
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.
Best for · Drift diving on wallsCozumel
MexicoMarine-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.

- Horizon Divers & Rainbow Reef Dive Center (Key Largo): 5-Star PADI CDC facilities with extensive boat fleets running morning shallow reef trips and afternoon wreck charters.
- Captain’s Corner / Lost Reef Adventures (Key West): Specialized daily charters to the Vandenberg and western coral reefs.
- Blue Star Dive Operators: Look for operators recognized with NOAA’s Blue Star certification, indicating strict adherence to responsible eco-diving practices and reef preservation.
The Diving Experience
The diving here caters to two distinct extremes:
- The Reefs: Sites like John Pennekamp Coral Reef State Park in Key Largo offer extremely shallow (10m/30ft), warm, and easy diving perfect for families and newly certified Open Water divers.
- The Wrecks: For Advanced and Tech divers, the Keys are a playground. The Spiegel Grove, the USS Vandenberg, and the USCG Duane sit in deeper water and often experience strong currents. These are challenging, deeply rewarding dives.
Marine Life Highlights
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.
Best for · Turtles, easy shore divesGili Islands
IndonesiaA 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.
Top dive sites
- Submerged pinnacle (10–18m) with dozens of resident green and hawksbill turtles
- 30mShark PointSloping reef and deep canyons (12–30m) with reef sharks and schooling trevally

Why Dive the Gili Islands?
Located just off the northwest coast of Lombok (and a fast boat ride from Bali), the Gili Islands are a backpacker and diver 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.
PADI & SSI Training Routes in the Gili Islands
The three Gili islands offer ideal progression from calm sandy slopes to fast inter-island drifts:
- Open Water Course (Dives 1 & 2 · 6–12m): Conducted at Turtle Heaven (Gili Meno) or Halik Shallows (Gili T), providing sandy pockets for skill work with guaranteed turtle encounters.
- Open Water Course (Dives 3 & 4 · 12–18m): Moving onto Shark Point Shallows or Hans Reef (Gili Air) to practice buoyancy and gentle current drift control.
- Advanced Open Water (Adventure Dives · 18–30m):

The Diving Experience
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.
- Currents: While you might experience mild currents, they are rarely overwhelming, and the boat crews are experts at dropping you precisely where you need to be.
- Logistics: Dive trips are incredibly short. You gear up at the shop, walk onto the boat, and are at the dive site within 10 to 15 minutes.
Marine Life Highlights
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.
Best for · Cheapest certificationKoh Tao
ThailandKnown 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.
Top dive sites
- Deep granite pinnacle (14–35m), chance for whale sharks (Advanced required)
- Gulf of Thailand's premier seamount with vertical 'Chimney' cave (10–35m)
- Granite mountain range covered in anemones and chevron barracuda
- Sunken WWII landing craft with intact deck cannons at 30m
- Shallow, calm bay (4–14m) ideal for Open Water training and relaxed fun diving
- #1 PADI Open Water training site in Asia with pool-like conditions
- Koh Tao's #1 night diving destination and multi-level granite garden
- 26mShark IslandRugged rocky islet with purple soft corals, leopard sharks, and whale sharks
- 25mGreen RockExciting swim-through boulder labyrinth and the famous Trigger Pit
Why Dive in Koh Tao?
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.
PADI & SSI Training Routes on Koh Tao
Koh Tao certifies more divers annually than almost anywhere else on Earth. The island has perfected a clear, structured training progression:
- Open Water Course (Dives 1 & 2 · 3–10m): Conducted at Japanese Gardens (Koh Nang Yuan) or Mango Bay, featuring wide white sand patches and shallow coral bommies where students demonstrate buoyancy control and mask removal.
- Open Water Course (Dives 3 & 4 · 10–18m): Progressing to White Rock or Twins, introducing compass navigation, buddy communication, and marine life identification.
- Advanced Open Water (Adventure Dives · 18–30m):
- Deep Dive: Chumphon Pinnacle (30m) or Southwest Pinnacle (28m).
- Wreck Dive: HTMS Sattakut (30m) exploring exterior deck guns and wheelhouse.
- Navigation / PPB: Green Rock maneuvering through granite swim-through tunnels.
- Night Dive: White Rock watching hunting barracudas and bioluminescent plankton.
- The Ultimate Day Trip: Sail Rock (Hin Bai), renowned for its vertical 18m “Chimney” swim-through.
Local Dive Centre Intel & Standards
Koh Tao is home to over 60 dive schools centered around Sairee Beach, Mae Haad, and Chalok Bay:
- Ban’s Diving Resort / Big Blue Diving / Crystal Dive: Massive 5-Star PADI CDC and SSI Diamond instructor training centers with dedicated classroom campuses and multi-depth training pools.
- Scuba Shack / Roctopus / The Hive: Boutique eco-friendly dive shops offering small maximum 4:1 student-to-instructor ratios.
- DMCR Marine Environmental Guidelines: Divers are strictly instructed never to touch marine life, feed fish, or wear reef-damaging gloves.
The Diving Experience
Diving in Koh Tao is characterized by massive granite pinnacles that rise from the sandy seabed. These underwater mountains create a thriving ecosystem.
- Beginners: You will likely spend your first few dives at sites like Japanese Gardens or Mango Bay. These are shallow, sandy bays dotted with hard coral heads. They look like aquariums and are completely protected from the wind.
- Advanced Divers: Chumphon Pinnacle and Southwest Pinnacle are the main draws. These are deeper sites (reaching down to 30m) where you can swim through schools of thousands of barracuda and trevally.
The Whale Shark Factor
Koh Tao is one of the most reliable places in Thailand to encounter whale sharks. They are frequently spotted at the offshore pinnacles—particularly Chumphon Pinnacle and Sail Rock—between March and May, and again between September and October. Seeing a 6-meter gentle giant cruise through a school of barracuda while you are completing your Advanced Open Water course is an experience you will never forget.
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.
Above the Surface
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.
Best for · Closest trip from the UKTenerife

- Moana Diving / Deep Ocean Diver (Radazul): Specializing in shore-based deep training and Freediving/Tech courses.
- Diving Los Gigantes: The only dedicated center operating directly beneath the 600m cliffs of Los Gigantes.
The Diving Experience
The diving in the Canary Islands is defined by what the volcanoes left behind.
- Topography: You will dive through massive basalt columns, deep lava tubes, and dramatic drop-offs. The architecture of the dive sites is often more impressive than the marine life.
- Conditions: The water here is Atlantic, meaning it is cooler than tropical destinations (ranging from 18°C in winter to 24°C in summer). A 5mm or 7mm wetsuit is mandatory for most of the year.
Marine Life Highlights
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.

The Diving Experience
The diving here is laid-back and easy, perfect for ticking off your Open Water or Advanced certifications.
- The Reefs: The reefs around Utila are generally sloping and forgiving. While the coral might not be quite as dramatic as neighbouring Roatan, the sheer volume of marine life makes up for it.
- The Wrecks: The Halliburton wreck provides an excellent, accessible deep dive for those completing their Advanced Open Water course.
Marine Life Highlights
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.
