Volcanic walls and canyons where the Kuroshio mixes temperate and tropical life

Batanes, the northernmost province of the Philippines, lies 162 km north of Luzon and closer to Taiwan than to Manila. Its 10 volcanic islands keep their drama underwater: the sheer North Wall, the channels and swim-throughs of Canyons, the boulder field at Boulder Point. Tropical reef fish mix here with temperate influences from the Kuroshio Current, giant trevally patrol Trevallies Lair, and even in the peak months a boat may have a site to itself.
About diving in Batanes
Diving is centred on Batan Island. Day boats leave from Chanarian Beach, and the sites cluster along the Batan coast with boat rides under 30 minutes. Conditions change quickly, so guides assess the sea each day and choose sites to match; when conditions stop the boat, the house reef off Chanarian Beach is the fallback, entered from shore. Rental equipment is limited, and a personal computer and surface marker buoy are treated as essential.
The same volcanic forces behind the islands' rolling hills shaped the seabed into walls, canyons and boulder fields. Pavona and Porites build the hard-coral framework, with branching Acropora in the shallows, and soft corals and gorgonians flourish on the walls and current-exposed faces. Surgeonfish, fusiliers and anthias school in the water column in densities that reflect low fishing pressure, and groupers grow to sizes rarely seen at busier destinations. Cuttlefish and octopus hunt through the reef and rubble.
Batanes suits intermediate to advanced divers with logged experience who are comfortable with variable conditions. Trevallies Lair and North Wall take moderate to strong currents on spring tides, and Open Water divers are limited to Chanarian Reef and, in calm conditions, Boulder Point. The province has no hyperbaric chamber, so any diving emergency means evacuation to Manila.

The year opens in the northeast monsoon. From December to February the water drops to 24 to 26 °C and the seas can turn rough enough to limit boat diving. March to May is the peak: calm seas, water at its warmest at 26 to 28 °C, and visibility reaching 25 to 30 m on good days. June to November is typhoon season, with a high chance that both flights and dives are cancelled, and most visitors who come to dive avoid it entirely.
Dive types & marine life
Giant trevally are resident at Trevallies Lair, where schools of jacks and occasional barracuda pass through. Hawksbill turtles are seen regularly and green turtles less often. Nudibranchs include both tropical and cooler-water species, and night dives at Boulder Point turn up reef lobsters and shrimp.

Questions divers ask
What certification do the best Batanes dive sites need?+
Advanced Open Water covers Trevallies Lair, Canyons and North Wall. Canyons can run moderate to strong currents, so experience in current is recommended there as well.
What fees do divers pay in Batanes?+
A Batanes Environmental Fee of PHP 350 (about USD 6) is collected at Basco Airport on arrival and funds environmental management across the province, including marine protection. A visit to Sabtang Island adds a community fee of PHP 200 to 300.
What wetsuit is needed for diving in Batanes?+
A 5 mm wetsuit suits most divers, as the water runs notably colder than at typical Philippine destinations; a 3 mm leaves little margin over repeated dives in a day.
