Tubbataha Reef is the Philippines’ most remote and most pristine dive destination — a UNESCO World Heritage Site sitting in the middle of the Sulu Sea, accessible only by liveaboard from Puerto Princesa in Palawan. There are no day trips to Tubbataha. No resorts. No restaurants. Just two atolls of untouched coral reef rising from 400 metres of open ocean, surrounded by some of the richest marine life in the world. If you want to dive Tubbataha, you plan ahead, save up, and commit to a week-long liveaboard expedition.
Why Tubbataha Reef is Special
Tubbataha was declared a National Marine Park in 1988 and inscribed as a UNESCO World Heritage Site in 1993. The 97,030-hectare marine protected area encompasses the North Atoll, South Atoll, and Jessie Beazley Reef — together representing one of the most ecologically intact coral reef systems in Southeast Asia.
The isolation is the key. Tubbataha sits 180km southeast of Puerto Princesa, too far for day boats, effectively protecting it from the fishing pressure and anchor damage that has degraded reefs closer to shore. The result is wall diving with visibility regularly exceeding 30 metres, reef fish in densities rarely seen elsewhere, and pelagic encounters that have become Tubbataha’s trademark — hammerhead sharks, whale sharks, manta rays, and large schools of barracuda and tuna on the open water walls.
What You’ll See at Tubbataha
Tubbataha has been surveyed to contain over 600 fish species, 360 coral species, and 11 species of shark. It is one of the few places in the world where you can reliably see large pelagics in large numbers. What divers typically encounter:
Sharks: Whitetip and blacktip reef sharks are present on virtually every dive. Grey reef sharks patrol the outer walls. Schools of hammerheads are a regular sighting on the deeper dives, particularly at the North Atoll walls and Shark Airport — a cleaning station where sharks queue to be cleaned by wrasse. Whale sharks appear throughout the season, particularly in March and April.
Rays: Manta rays are common at both atolls. Tubbataha is one of the most consistent manta-sighting spots in the Philippines. Eagle rays, marble rays, and blue-spotted ribbontail rays round out the ray diversity.
Turtles: Green and hawksbill turtles nest on the sand cays at both atolls. Underwater encounters are frequent — divers regularly find turtles resting on coral heads or gliding past on the walls.
Pelagics: Schools of yellowfin tuna, dogtooth tuna, barracuda, and jacks are a constant presence on the outer walls. Tubbataha sits in open Sulu Sea, and the big-water feeling of the dives reflects this.
Reef life: The hard coral coverage at Tubbataha averages over 70% — exceptional by any global standard. Napoleon wrasse, bumphead parrotfish, and schools of surgeonfish are resident. The macro life is also excellent: ornate ghost pipefish, Coleman shrimp, and various nudibranch species reward patient divers between pelagic encounters.
Best Dive Sites at Tubbataha
Shark Airport (North Atoll)
The most famous dive site in Tubbataha — a cleaning station at 20–30 metres where grey reef sharks and whitetip reef sharks gather in numbers to be cleaned by cleaner wrasse. The name comes from the orderly queueing behaviour. Best at incoming tide when the cleaning stations are most active.
Wall Street (North Atoll)
A vertical wall dropping from 5 metres to beyond 400 metres — one of the most dramatic reef structures in the Philippines. The wall is encrusted with sea fans and soft corals, and the open-water side hosts large pelagic schools. Strong currents on the outer wall concentrate fish and create the conditions that make Tubbataha diving so memorable.
South Atoll Walls
The South Atoll has slightly less current than the North and is often preferred for its prolific soft coral gardens and regular manta ray sightings. The sand cay at the South Atoll is a nesting site for boobies and frigatebirds — surface intervals spent watching seabird colonies are part of the Tubbataha experience.
Jessie Beazley Reef
A submerged reef between the two atolls, often dived on the transit between them. Regularly produces hammerhead sightings and large pelagic schools. Not always accessible depending on currents and conditions.
How to Get to Tubbataha Reef
There is only one way to dive Tubbataha: a liveaboard boat operating from Puerto Princesa, Palawan. The crossing takes approximately 10–12 hours each way. Liveaboards spend 6–7 nights at the reef, conducting 3–5 dives per day. The most reputable operators include:
MV Stella Maris Explorer — one of the longest-running Tubbataha operators, based in Puerto Princesa. Wooden Philippine vessel with comfortable cabins and a strong dive crew.
MV Discovery Palawan — part of the Discovery Fleet operating from Puerto Princesa. More modern vessel with air-conditioned cabins and nitrox available.
MV Infiniti — another established liveaboard operator making the Puerto Princesa to Tubbataha run.
Trip prices range from USD 2,500 to USD 4,500+ depending on the vessel, cabin type, and inclusions (nitrox, marine park fees). The Tubbataha Protected Area Management Board (TPAMB) charges a mandatory marine park entry fee of around USD 150 per diver per trip, included by most operators.
When is Tubbataha Open?
Tubbataha is open to liveaboards only during the dry season: mid-March to mid-June. Outside these months, the Sulu Sea weather makes the crossing and the diving unsafe. The peak months for marine life encounters are April and May — whale sharks are most common in April, and sea conditions are generally calmer by then. March can still have some rough weather; June sees the start of the southwest monsoon.
Trip slots book out months in advance, particularly for the prime April–May window. If you’re planning a Tubbataha trip, contact operators in October or November for the following season’s bookings.
Experience Level Required
Tubbataha is not a beginner destination. The dives involve strong, unpredictable currents, significant depths (many sites are best dived at 20–30 metres), limited shore access, and open-ocean conditions. Most liveaboard operators require PADI Advanced Open Water certification as a minimum, with a preference for divers who have experience in current diving and significant logged dives.
That said, Tubbataha does not require technical diving certification — experienced recreational divers can fully access the best dive sites. The value of experience here is not depth but comfort: the ability to maintain position in current, control buoyancy precisely (the reef is fragile and reef contact is strictly prohibited), and manage open-water exits when conditions deteriorate.
Conservation Rules at Tubbataha
Tubbataha is a strictly enforced marine protected area. Anchoring on reef is prohibited — liveaboards use only designated mooring buoys. No fishing, no collecting of any kind (shells, coral, marine life), and no touching of the reef. Violations result in fines and removal from the park. Rangers are stationed on both atolls year-round and board visiting liveaboards to conduct briefings and checks. The rules are taken seriously and compliance is near-universal.
