Best Dive Sites in Anilao, Batangas: The Complete 2026 Guide

Anilao, Batangas sits about 140 kilometres south of Manila on the Calumpan Peninsula, at the heart of the Verde Island Passage — the stretch of water marine scientists have called the "centre of the centre" of the world's shorefish biodiversity. That is why more than 40 named dive sites are packed into this short coastline, ranging from silty muck dives crawling with rare critters to current-swept seamounts and gentle coral gardens perfect for a first open-water dive.

Twin Rocks

A long-established marine sanctuary and one of Anilao's most beginner-friendly reefs. Two large boulders sit a metre apart, surrounded by a coral garden that reaches down to roughly 16 metres. Expect schooling jacks and dense reef fish over the hard coral, plus resident juvenile hawksbill turtles and a strong supporting cast of macro life — nudibranchs, pipefish, seahorses and scorpionfish tucked into the reef.

Cathedral

Cathedral is one of Anilao's signature dives: a pair of coral-encrusted rocks on an 18-metre seabed with a stone cross planted between them. The sheltered profile and easy depth make it another approachable site, with clouds of reef fish, healthy coral and frequent hawksbill turtle sightings.

Secret Bay (Mainit Muck)

Arguably the most famous muck dive in Anilao. The bottom is dark volcanic sand and rubble from around 5 to 21 metres — low on scenery, extraordinary on critters. Mantis shrimp, gobies, wonderpus octopus, seahorses and nudibranchs are regulars, and between November and March cuttlefish and squid arrive in numbers. Night dives here are exceptional.

Sombrero Island

A short boat ride offshore, Sombrero Island offers a sloping reef and wall dressed in large gorgonian sea fans and soft corals, typically dived between about 15 and 30 metres. Mild-to-moderate currents can run here, making it a satisfying step up for intermediate divers who want both wide-angle scenery and macro subjects on the same dive.

Kirby's Rock

Sitting off Tingloy Island in the Verde Island Passage, Kirby's Rock is a seamount that rises from around 30 metres to just a few metres below the surface. Seasonal currents sweep nutrients past the wall, pulling in schooling jacks and giant trevally, while a large submerged boulder on the deeper side is bedecked in sea fans and crinoids — a classic spot to search the gorgonians for golden pygmy seahorses.

Anilao Pier

Don't be put off by the humble setting: the sand and rubble under Anilao Pier, only about 12 metres deep, is a superb muck site and a favourite dusk and night dive. Cephalopods, nudibranchs and crustaceans come out as the light fades, making it an easy, shallow finish to a diving day.

Ligpo Island

For divers with a little more experience, Ligpo Island combines a wall, a pinnacle and soft-coral gardens with depths reaching about 35 metres. Currents can be brisk, and the reward is a mix of the very small and the larger: tiny colourful nudibranchs, pygmy seahorses and shrimp alongside patrolling hawksbill turtles.

Dive Planning Tips

• During the busy season (roughly March to June) it pays to arrange your dives a day ahead — the most popular sites can get crowded.
• Always complete a site briefing with your guide. Current direction and entry points change with the tides, especially at Secret Bay and Kirby's Rock.
• Carry a surface marker buoy (SMB) for open-water and drift sites, and signal your ascents.
• Match the site to your certification and comfort: Twin Rocks, Cathedral and Anilao Pier suit newer divers, while Kirby's Rock and Ligpo reward more experience.
