Philippines Diving Guide: Why Tubbataha and Coron Are World-Class
If you are serious about diving, the Philippines should be on your list. Two destinations demand your attention: Tubbataha Reef and Coron Bay. They offer entirely different experiences. Tubbataha is a remote, pristine atoll with powerful currents and pelagic action. Coron is an underwater museum of WWII shipwrecks. Both are world-class. As an instructor who has logged hundreds of dives across the archipelago, I can tell you that most divers make the mistake of trying to cram both into one trip. That is possible but not ideal. The better approach is to understand what each location offers and plan accordingly.
Tubbataha Reef: Pristine Wilderness and Pelagic Encounters
Tubbataha Reef is a UNESCO World Heritage Site located in the middle of the Sulu Sea. It is a marine protected area with strict regulations. There are no resorts. No beach bars. Only liveaboards. This is not a place for casual snorkeling. It is for serious divers who want to see big marine life in a pristine environment. The season runs strictly from March to June. Outside those months, the weather makes the crossing unsafe and visibility drops.
Dive conditions here demand respect. Currents can rip through the channels between the atolls. You need to be comfortable with drift diving and have good buoyancy control. Most dives are in the 20 to 40-meter range. Water temperature hovers around 26 to 30°C. A 3mm wetsuit is fine, but some divers prefer a 5mm for multiple dives or if you get cold easily. The marine life is extraordinary: whitetip and gray reef sharks, hammerheads, mantas, sea turtles, and massive schools of jacks and barracudas. The coral cover is among the healthiest I have seen anywhere in the world.
Top Dive Sites in Tubbataha Reef
North Wall – This is the signature dive. Currents attract big pelagics. You might see sharks, mantas, and tuna. The wall drops to over 100 meters. Dive at slack tide if you prefer calm conditions, but the current brings the action. Depth ranges from 10 to 40 meters.
South Wall – Less current than the north side. Excellent coral gardens and cleaning stations. You can spend an entire dive watching turtles get cleaned. Great for macro life too: frogfish, nudibranchs, and pygmy seahorses.
Black Rock – A seamount that rises from the deep. This is where you find sharks. Gray reef sharks patrol the area constantly. Barracudas and jacks form huge schools. The current can be strong, so plan your descent and ascent carefully.
Coron Wrecks: A History Lover’s Underwater Museum
Coron Bay is a different world. The Japanese sank a fleet of supply ships here in 1944 during the Battle of Leyte Gulf. The wrecks sit in relatively shallow water, between 10 and 40 meters. Many are intact and accessible to recreational divers. You do not need technical certification to see the best ones. That makes Coron a fantastic destination for divers who want wreck exploration without extreme depth.
Visibility varies. It can be 15 meters on a good day, sometimes less after rain. The water is warm, typically 28 to 30°C. Currents are usually mild compared to Tubbataha. But do not be fooled inside the wrecks. Penetration diving requires proper training and a guide. Silt can reduce visibility to zero in seconds. Always bring a torch, even for the shallowest wrecks.
Top Wreck Dives in Coron Bay
Irako – This refrigerated supply ship sits at 36 meters maximum depth. It is one of the most intact wrecks. Penetration opportunities are extensive. You need advanced open water certification and wreck specialty recommended. The engine room and refrigeration compartments are the highlights.
Akitsushima – A seaplane tender with a massive crane. The wreck rests on its side in 22 to 36 meters of water. The deck gun is spectacular. This is an easier wreck for open water divers who want to see a large ship without needing deep penetration. The propeller and rudder are massive.
Kyokuzan Maru – A cargo ship sitting upright in 22 to 36 meters. The mast reaches up to 10 meters, making it a good shallow dive option. The cargo holds still contain vehicles and equipment. This is a great introduction to Coron’s wrecks.
Olympia Maru – A former passenger-cargo ship now resting in 12 to 36 meters. It is less visited than the others, which means fewer divers. The wreck is partially collapsed in some areas but still offers good penetration possibilities. You will see a bathtub and porcelain toilets scattered on the deck.
Philippines Diving Logistics: When to Go and How to Book
Timing is everything. Tubbataha is only accessible from March to June. The best months are April and May when visibility peaks at 30 to 40 meters. Late June can bring early swell from the southwest monsoon. Book your liveaboard at least six months in advance. Permits are limited to protect the reef.
Coron is diveable year-round. The optimal season is November to May. The rainy season from June to October brings reduced visibility and occasional typhoons. But even during the rainy season, you can find good days. Just be flexible with your schedule.
Getting to Tubbataha requires flying into Puerto Princesa, Palawan. The liveaboard departs from there. For Coron, fly into Busuanga Airport (USU). Direct flights from Manila and some international connections. From the airport, it is a 30-minute drive to Coron Town. Dive operators and resorts are clustered along the bay.
Liveaboard vs. Resort-Based Diving: What Suits You Best?
Tubbataha is exclusively liveaboard. There are no land-based options. You live on a boat for five to seven days. This means up to four dives per day, meals included, and a small cabin. It is not luxury cruising. It is a dive-centric trip. You get tired but the diving is unmatched.
Coron offers both. Liveaboards in Coron typically run three to five days and cover the wrecks plus nearby reefs. Resorts let you sleep on land and do day trips. This is more comfortable and allows for rest days. You can also combine Coron with other destinations like El Nido or Apo Reef.
If you want maximum dive time, choose a liveaboard for Coron. If you want flexibility and comfort, go with a resort. For Tubbataha, you do not have a choice – and that is part of the appeal.
Packing and Dive Readiness for Tubbataha and Coron
- Wetsuit: 3mm is sufficient for both destinations. A 5mm is better if you are doing multiple dives daily or get cold easily.
- Dive computer: Essential. Currents and multi-level diving demand it.
- Torch/light: Required even for shallow wrecks. Silt makes everything dark.
- Surface signaling device: SMB or DSMB. You will drift, and boats need to see you.
- Reef-safe sunscreen: No exceptions. Environmental laws are strict.
- Certification: AOW is the minimum for Tubbataha’s conditions. For Coron, OW is fine for some wrecks, but penetration requires AOW and ideally a wreck specialty.
- Dive insurance: Mandatory. DAN or equivalent. No operator will take you without it.
- Camera: GoPro or compact housing is fine. Wide-angle for Tubbataha. Macro for Coron’s wrecks.

Final Pro Tips: Making the Most of Your Philippines Dive Trip
- Arrive at least one day early. Jet lag and travel fatigue affect your diving. A day of rest reduces risk and improves enjoyment.
- Eat local food but be cautious. The Philippines has amazing seafood. Stick to properly cooked meals before dive days.
- Bring a dive watch or timer. Many sites require you to monitor your bottom time manually, especially on wrecks.
- Respect the rules. Tubbataha has strict no-touch policies. Fines are serious. Do not take souvenirs from wrecks.
- Learn basic Tagalog phrases. ‘Salamat po’ (thank you) goes a long way with locals.
After guiding dozens of trips through these waters, my best advice is to choose one destination and do it properly. Tubbataha and Coron are not interchangeable. They are both extraordinary in their own way. Pick the one that matches your diving style and go deep. Online Scuba Directory – your gateway to the deep.
