Ten of the world's great dive regions — from Sipadan's permit-capped walls to the Galápagos liveaboard circuit — with the permits, park fees and seasonal closures each one enforces in 2026, destination-specific do's and don'ts, and key entries, moorings and dive sites with approximate GPS coordinates plotted on a map.
10 destinations · rules and fees last verified 2026-08-13
Coordinates are approximate reference points (WGS84) for planning and orientation — never navigation data. Dive with licensed local operators, current charts and a briefing; entries, moorings and buoys move. Permit rules, park fees and seasonal closures change often; confirm on the official pages linked under each destination before you book.
Southeast Asia
Sipadan Malaysia
A limestone pinnacle rising 600 m off the Celebes Sea floor, ringed by walls that drop straight off the beach reef. Barracuda tornadoes, bumphead parrotfish at dawn and more green turtles per tank than anywhere else in Asia.
Skill levelAdvanced Open Water (or equivalent) required
Daily permits≈250/day via Sabah Parks, allocated to resorts
Park fees≈RM450/day foreign divers (usually bundled)
SeasonDec–Oct · island closed every November
SignatureBarracuda Point tornado · turtle traffic
Permits & booking: No permit, no dive: Sabah Parks caps Sipadan at roughly 250 permits a day (raised from the old 176), issued only through the resorts and dive centres around Mabul and Semporna — you cannot buy one independently. Book a 3–5 night package 1–2 months ahead; resorts rotate their small daily allocations among guests, so longer stays mean more Sipadan days. Two dives a day at Sipadan since 2023, mornings usually, and bring your Advanced card — it is checked.
✓ Do
Carry your certification cards and logbook — permits name the diver, and rangers check them on the jetty.
Stay at Mabul or Kapalai and dive their muck sites on non-permit days — the macro life rivals Sipadan's big stuff.
Book the permit nights first, then flights to Tawau — packages without a confirmed permit allocation are the classic trap.
Bring reef-safe sunscreen and a surface marker buoy; currents at Barracuda Point can push fast.
✕ Don't
Don't plan Sipadan for November — the island closes to divers for its annual rest period.
Don't expect night dives or stays on Sipadan itself — the island has been resort-free since 2004 and daylight visits only.
Don't touch or chase the turtles — rangers do pull permits for harassment.
Don't book with operators promising 'guaranteed daily Sipadan' for walk-ins — allocations don't work that way.
Granite boulders, white-sand channels and Thailand's clearest water — then Richelieu Rock, a purple-soft-coral seamount that is the country's best single dive site and its most reliable whale-shark stop.
SeasonOpen 15 Oct – 15 May only (monsoon closure)
Park fees500 THB entry + 200 THB/day diving (foreigners)
AccessLiveaboards & speedboats from Khao Lak / Phuket
SignatureRichelieu Rock — whale-shark magnet (Surin park)
Permits & booking: Mu Ko Similan National Park closes completely from mid-May to mid-October and can shut early in bad monsoon years; inside the season foreigners pay 500 THB entry plus a 200 THB daily diving fee, collected by your operator. Richelieu Rock sits in neighbouring Mu Ko Surin National Park with its own entry fee. Liveaboards (2–5 nights out of Thap Lamu pier) cover Similan, Koh Bon, Koh Tachai and Richelieu in one loop and sell out over New Year — book weeks ahead. Day-trip speedboats reach Similan year-round within the season but make Richelieu a long day.
✓ Do
Time Richelieu Rock for February–April if whale sharks are the goal — plankton blooms bring them through.
Pick a liveaboard with Koh Bon and Koh Tachai on the itinerary — manta cleaning stations sit off both.
Carry your certification card and insurance — park rangers and operators both check.
Recheck the closure dates the season you travel — the park has closed as early as 15 April in rough years.
✕ Don't
Don't book Similan for June–September — the park is closed, full stop, and 'secret trips' are illegal.
Don't touch the rock at Richelieu — everything on it stings, and gloves are banned in Thai parks.
Don't fly a drone in the park without DNP permission — confiscation is routine.
Don't expect to stay overnight on the islands — camping and island accommodation were removed; boats only.
Where the Pacific and Indian Oceans force tides between islands guarded by dragons: current-swept pinnacles carpeted in life, reliable manta squadrons at Karang Makassar, and reef health that repays every knot of drift.
SeasonYear-round diving · calmest seas Apr–Nov
Park fees≈IDR 300k/day for a diver (entry + surcharges)
BookingSIORA advance booking via licensed boats (2026)
CurrentsStrong & tidal — drift experience advised
Permits & booking: Fees are per-day and modest — about IDR 250,000 marine-park entry plus small diver and harbour surcharges (≈IDR 300,000 total) — but since April 2026 every visitor must be booked in advance through the SIORA system by a licensed boat operator; walk-in tickets are gone and daily zone quotas apply (Manta Point caps at 150). Base in Labuan Bajo (Flores) and choose between day boats, multi-day phinisi liveaboards, or dive-resort speedboats. Ask specifically how your operator times Batu Bolong and Castle Rock for slack water — the answer tells you whether they respect the currents.
✓ Do
Carry reef-hook experience (or ask for a briefing) before Castle Rock and Crystal Rock — the north's sites fire in current.
Visit the dragons on Rinca or Komodo with the ranger fee paid — it's a group rate and rangers walk with you.
Check your operator holds the 2026 SIORA licence — unlicensed boats get turned back at the gate.
Keep 5 m off the mantas at Karang Makassar and let them come — cleaning-station etiquette is enforced.
✕ Don't
Don't dive Manta Point when the quota's full and your boat 'knows a way' — rangers log hulls.
Don't wander on dragon islands without a ranger — komodo bites are rare because the rules work.
Don't fly drones without the IDR 2,000,000 park permit arranged in advance.
Don't chase slack-tide sites on a fixed clock — tides rule the schedule here, not the itinerary.
The planet's largest reef system — 2,300 km of it. Day trips hit the mid-shelf gardens; the reason divers cross the world is further out: Ribbon Reef pinnacles, Osprey's shark-patrolled walls, and one of the world's great wrecks at Yongala.
SeasonYear-round · stinger suits Nov–May
Reef chargeEMC A$8 full day / A$4 part day (via operators)
AccessCairns & Port Douglas day boats; liveaboards north
SignatureCod Hole potato cod · SS Yongala wreck
Permits & booking: No individual permit — commercial operators are licensed by the Reef Authority and collect the Environmental Management Charge (A$8 for a full day, A$4 part-day, unchanged for the year from 1 April 2025) with your trip fare. Day boats run daily from Cairns and Port Douglas; the Ribbon Reefs and Osprey Reef need a 3–7 night liveaboard out of Cairns. The SS Yongala runs as a separate day trip from Townsville or Ayr and is worth the detour — book it around neap tides for kinder current.
✓ Do
Wear the stinger suit November–May — irukandji and box jellyfish are a real risk inshore.
Choose High Standard Tourism operators (Reef Authority certified) — smaller groups, better briefings.
Book Yongala with a marine-park-moored operator and treat it as an advanced dive — it sits in open water at 14–28 m.
Log your EMC receipt — it funds reef management and operators must itemize it.
✕ Don't
Don't touch or stand on coral — fines under the Marine Park Act are enforced, and bleached reef recovers slowly.
Don't penetrate the Yongala — it is a protected historic shipwreck and entry is prohibited.
Don't fly drones from boats without the operator's permit — most reef waters are regulated airspace.
Don't skip the 18–24 h no-fly window after repetitive dives — Cairns flights tempt tight schedules.
The world's most famous cold-current crossroads: hammerheads by the hundred, whale sharks the size of buses at Darwin, marine iguanas grazing underwater — a park where the diving is as regulated, and as rewarded, as anywhere on earth.
Park feeUS$200 foreigners (cash, doubled Aug 2024) + US$20 TCT
DivingLiveaboard-only for Wolf & Darwin · advanced profiles
SignatureHammerhead schools · whale sharks at Darwin
Permits & booking: Every visitor pays the Galápagos National Park entrance fee — US$200 for foreign adults since August 2024 (US$100 under-12s), cash on arrival — plus a US$20 Transit Control Card arranged before departure from Quito or Guayaquil. Dive sites themselves are permit-managed through licensed operators only. The famous walls at Wolf and Darwin are liveaboard-only, typically 7 nights, and berths sell out ~a year out for Jun–Nov whale-shark season. Land-based diving from Puerto Ayora reaches Gordon Rocks (the hammerhead 'washing machine') on day boats — advanced cert usually required.
✓ Do
Bring US dollars cash for the park fee — card terminals at Baltra are not a thing to bet a trip on.
Pack a 7 mm wetsuit, hood and gloves-rated tolerance for Jun–Nov — the Humboldt current earns its fish.
Use a reef hook and SMB at Wolf/Darwin — surge, current and down-wellings are standard conditions.
Book the TCT online at least a week before flying — airlines check it at the gate in Quito/Guayaquil.
✕ Don't
Don't touch, feed or block any animal — 2 m minimum distance is park law, above and below water.
Don't bring organic material between islands — biosecurity checks are serious and fines real.
Don't attempt Wolf/Darwin as your first cold-current trip — operators can and do refuse profiles.
Don't fly home within 24 h of a liveaboard's last dive day — itineraries build the gap in; keep it.
A shark sanctuary the size of France's EEZ wrapped around 300 mushroom-shaped islands: hooks in at Blue Corner while grey reefs patrol the wall, mantas queue in German Channel, and a lake full of sting-less jellyfish pulses gold an hour from town.
SeasonOct–May peak · diveable year-round
PermitsRock Islands $50/10 days · +Jellyfish Lake $100/5 days
Arrival feeUS$100 PPEF bundled into your airfare
SignatureBlue Corner on a reef hook · WWII wrecks
Permits & booking: Koror State sells two permits: Rock Islands only (US$50, 10 days) or Rock Islands + Jellyfish Lake (US$100, 5 days) — carried on the boat and checked by rangers. The national US$100 Pristine Paradise Environmental Fee is already inside your international air ticket, and Jellyfish Lake itself is snorkel-only: scuba bubbles harm the jellies and the deep layer is toxic hydrogen sulfide. Dive shops in Koror run fast boats through the Rock Islands to Blue Corner, German Channel and the wrecks; liveaboards add Peleliu and dawn slots. Reef-hook technique is taught here — take the lesson, it defines the country's signature dive.
✓ Do
Learn the reef hook before Blue Corner — hooked in, hands free, the show comes to you.
Snorkel Jellyfish Lake with slow fins and no sunscreen residue — shower first, vest on, touch nothing.
Visit the WWII wrecks (Iro Maru, Chuyo Maru) on surface intervals — history at 20–35 m inside the lagoon.
Check whether your flight already carried the PPEF — it does; keep boarding passes for any dispute.
✕ Don't
Don't scuba dive Jellyfish Lake — banned outright, for the jellies' sake and yours (toxic deep layer).
Don't take anything, even shells — Palau's entire waters are a sanctuary and export is prosecuted.
Don't stand on ANY coral for a photo — guides will end the dive.
Don't book tight connections through Guam/Manila on the way home — island weather owns the schedule.
Where Sinai's desert plunges into 800 m of blue: the Shark & Yolanda drift past two coral towers and a cargo of 1980s bathroom fittings, and an hour west lies the Thistlegorm — a WWII supply ship still packed with motorbikes, trucks and locomotives.
SeasonYear-round · Mar–May & Sep–Nov sweet spots
Park fee≈US$10–15/day, collected by operators
AccessDay boats from Sharm el-Sheikh · wreck liveaboards
SignatureShark & Yolanda drift · SS Thistlegorm
Permits & booking: No individual permit: Ras Mohammed National Park charges an entry fee in the ~US$10–15/day range (it moves with the Egyptian pound) that boats fold into the trip price, and your operator handles the manifest. Carry your certification card and passport copy — checkpoints on the Sinai road ask. Sharm's jetties launch daily two- and three-tank boats to Ras Mohammed and the Tiran straits; the SS Thistlegorm runs as a long day trip or, better, a mini-liveaboard with dawn slots before the fleet arrives. Book Thistlegorm for a calm-weather window — it's an exposed crossing.
✓ Do
Dive Shark & Yolanda on the morning slot — the anthias walls and snapper schools peak before the crowds.
Do the Thistlegorm with nitrox and two tanks — one for the holds (guided), one for the deck gun and locomotives.
Check current conditions for Jackson Reef (Tiran) — the drift is glorious exactly when it's running.
Keep your fees receipt — park rangers board boats to spot-check manifests.
✕ Don't
Don't remove ANYTHING from the Thistlegorm — it is a war grave and protected wreck; artefact theft is prosecuted.
Don't touch the corals at Yolanda's 'bathroom display' for the photo — the toilets are colonized now.
Don't dive Ras Mohammed's outer walls without a guide — down-currents off Shark Reef are documented.
Don't book the cheapest boat on the jetty — compressor quality and briefings vary; CDWS membership is the floor.
The easiest serious diving on earth: a desert island whose entire leeward coast is a marine park, where you shore-dive a different yellow-stone site every tank and the house reef starts where the ladder ends.
SeasonYear-round — south of the hurricane belt
Nature feeUS$40 per calendar year, everyone 13+ in the water
Signature1000 Steps · Hilma Hooker wreck · Salt Pier
Permits & booking: One fee covers everything: STINAPA's US$40 nature fee (per person 13+, per calendar year — it expires every 31 December regardless of purchase date) is mandatory for diving, snorkeling and all water activities, and also admits you to Washington Slagbaai National Park. Pay online at stinapa.bonairenaturefee.org before you fly and keep the QR handy — dive shops check it at tank pickup. No boat needed for most of the island: rent a pickup, grab tanks, and follow the yellow painted stones down the leeward coast.
✓ Do
Do a check-out orientation dive with a local shop first — it's required before independent shore diving.
Dive Salt Pier around the pillars (permission posted when ships are berthed) — the sponge growth is absurd.
Keep gear in sight or in the truck cab at remote sites — petty theft from parked pickups is the island's one nuisance.
Snorkel Klein Bonaire's no-anchor reserve on a surface-interval water-taxi run.
✕ Don't
Don't wear gloves — they're banned in the marine park to keep hands off the reef.
Don't anchor anywhere — moorings only; anchoring on reef is the park's cardinal sin.
Don't buy single-use reef-toxic sunscreen — oxybenzone products are restricted; mineral only.
Don't skip the calendar-year detail — a late-December fee purchase expires within days.

Park ticketPARNAMAR R$384 foreigners / R$192 Brazilians · 10 days
SignatureSpinner dolphins · shark-rich 30 m visibility
Permits & booking: Two charges stack: the island's environmental preservation fee (TPA) of R$105.79 per person per day from 1 January 2026, paid online before or on arrival, plus the marine national park ticket (R$384 for foreigners, half for Brazilians, valid 10 days) for the park's beaches and dive zones. Flights from Recife or Natal only, and beds are capped — book accommodation before flights. Dive operators run morning two-tank boats from Porto de Santo Antônio; the season never closes, but August–December brings the calmest, clearest water.
✓ Do
Pay the TPA online (noronha.pe.gov.br) before you fly — the airport queue doubles otherwise.
Dive the Corveta V17 only if you hold the depth certification — the wreck starts past 50 m and is a technical dive.
Snorkel Baía do Sueste's turtle seagrass with the mandatory vest and no fins — rules are enforced by monitors.
Carry both fee receipts everywhere — checkpoints at park beaches scan them.
✕ Don't
Don't touch or block the spinner dolphins' bay entry — Baía dos Golfinhos is boat- and swimmer-free by federal rule.
Don't bring single-use plastics ashore — the island bans them at entry.
Don't count on cash machines — cards work, ATMs run dry; bring reais.
Don't overstay your TPA days — the exit check bills the difference with penalties.
The crack between two continents: a flooded rift where the North American and Eurasian plates pull apart, filled with glacier water filtered through lava for decades. The clearest water most divers will ever see — you hover over the planet's seam.
Water2–4 °C glacial melt · 100 m+ visibility
RequirementsDrysuit cert OR 10 logged drysuit dives (≤2 yrs)
Minimum age17 to dive, by Icelandic law
AccessGuided tours only — Þingvellir National Park
Permits & booking: Diving Silfra is only possible on a guided tour with a licensed operator inside Þingvellir National Park. To scuba dive you must hold Open Water plus either a dry-suit specialty or written proof of 10 logged dry-suit dives within the last two years; snorkelers need no certification. Tours meet at the Silfra car park (P5) year-round — the spring water holds 2–4 °C summer and winter. Book a morning slot in summer to beat the snorkel crowds, and be honest on the medical form: cold-water regulators and constricting suits are no place for surprises.
✓ Do
Bring your certification cards AND the drysuit proof — operators verify before they'll kit you up.
Eat and hydrate before the dive — cold works harder than depth here (max ~18 m, most of it shallower).
Sip the water mid-dive — it's purer than anything bottled, and every guide will offer.
Combine it with the Þingvellir rift walk topside — Alþingi's original site sits above the fissure.
✕ Don't
Don't touch the algae — the neon-green 'troll hair' tears off with a fin wash and takes years to regrow.
Don't dive within 24 h of flying INTO Iceland after diving elsewhere — the tour's altitude profile over Mosfellsheiði counts.
Don't expect marine life — Silfra is about geology and light; the char stay in the lake.
Don't skip gloves-and-hood drills if you're new to dry gloves — regulator recovery in 2 °C needs rehearsal.

Book the permit, then the flight
Every destination above fails the same way: the permit or the berth, not the diving. Sipadan is the extreme case — roughly 250 permits a day, issued only through resorts, which means the resort booking is the permit strategy and short stays get the leftovers. Galápagos dive liveaboards sell out close to a year ahead for whale-shark season; Komodo moved to compulsory advance booking through licensed operators in April 2026, killing the walk-in trip; and Thailand simply locks the Similan gate from mid-May to mid-October. Pick dates by when the bottleneck opens, not when flights are cheap, then build the surface days around it.
Fees are the easy part — budget for them and carry proof. The pattern in 2026: a per-entry or per-day park charge (Similan 500 THB + 200 THB/day diving, Komodo ≈IDR 300k/day, Ras Mohammed ≈US$10–15), a flat annual pass (Bonaire's US$40 calendar-year nature fee), a bundled arrival levy (Palau's US$100 PPEF inside the airfare), or a headline cash gate (Galápagos: US$200, in dollars, on arrival). Rules and amounts above were last verified August 2026 — they move nearly every season, which is exactly why each destination links its official source.
Coordinates, charts and honesty about depth
The coordinates in this guide are planning references — they get you to the right jetty, the right mooring field, the right briefing. They are not navigation data: dive sites are positions on a living sea floor, moorings get relaid, and a GPS point says nothing about the current running over it. Local operators run the approach; your job is to know roughly where you are so the plan makes sense. If you want to understand how divers record and share site positions properly — datums, decimal degrees versus DMS, mooring versus entry points — that's our dive-site coordinates article.
Depths shown are typical guided-profile depths, not maximums. Several sites here carry real teeth: the Corveta V17 at Noronha starts past 50 m (technical only), Yongala and Thistlegorm sit near 30 m in open water, and Galápagos adds current to everything. Match the site to the certification you actually hold — operators at every destination on this page will ask for the card, and the good ones refuse profiles, which is the correct answer.
Standards that travel with you
Three habits work at every latitude. First, insurance that explicitly covers diving and evacuation — remote regions like Socotra-grade islands, outer atolls and liveaboard routes are helicopter-and-days territory, not ambulance territory. Second, the no-fly window: 18–24 hours after repetitive diving, longer after multi-day liveaboards — build it into the itinerary as a topside day, not a hope. Third, operator licensing: Egypt's CDWS membership, the Reef Authority's certified operators in Australia, Komodo's 2026 SIORA licences, Sabah Parks' permit allocations — every serious dive economy has a licence floor, and the boats below it are cheap for reasons that surface underwater. When an operator's paperwork is in order, the compressor maintenance usually is too.
Frequently asked questions
Which diving destinations require permits booked in advance?
Sipadan is the strictest — roughly 250 permits a day issued only through resorts, so book a 3–5 night package 1–2 months ahead. Komodo requires advance booking through a licensed operator since April 2026 (no walk-in tickets), Galápagos dive liveaboards sell out close to a year ahead for Wolf and Darwin, and Silfra must be booked as a guided tour with drysuit credentials.
How much are marine park fees at the big dive destinations?
As of August 2026: Bonaire charges US$40 per calendar year for all water users 13+, the Great Barrier Reef adds A$8 per full day (EMC) via operators, Similan charges foreigners 500 THB entry plus 200 THB per diving day, Komodo works out around IDR 300,000 per diving day, Galápagos charges US$200 cash on arrival plus a US$20 transit card, and Palau bundles its US$100 environmental fee into the airfare with Rock Islands permits ($50–$100) on top. Fees change often — confirm on the official links in each destination block.
When do the seasonal closures fall?
Thailand's Similan Islands close completely from 15 May to 15 October (sometimes earlier in bad monsoon years). Sipadan closes to divers every November. The rest of the destinations in this guide dive year-round with better and worse seasons rather than closures — Galápagos splits into a warm clear season (January–May) and a cooler, fishier one (June–November).
Are the dive-site coordinates in this guide safe to navigate by?
No — they are approximate planning references (WGS84) for orientation, distances and trip logistics. Moorings move, entries depend on conditions, and marine navigation needs official charts and local knowledge. Dive with licensed operators, and treat every coordinate here as 'roughly where the briefing happens', not a waypoint to steer to.
