Best Dive Sites in Anilao: Top 10 Ranked
Anilao packs over 50 named dive sites into a 10-kilometer stretch of coastline — one of the highest densities of accessible diving on the planet. Most sites are a 10 to 25-minute boat ride from your resort. The diversity across such a compact area is remarkable: muck slopes, coral pinnacles, seamounts, vertical walls, deep caverns, and the Philippines' best blackwater diving.
The rankings below weight three things: what you'll actually see on a typical dive, the uniqueness of the experience relative to other destinations, and how consistently the site delivers. These are not based on seasonal exceptionalism — every site here performs at minimum well across at least six months of the year.
1. Secret Bay (Mainit Muck)
The most productive muck dive in the Philippines.
Depth: 3–21 m · Skill: Open Water+ (advanced buoyancy for muck) · Entry: Boat · Current: None at slack, destructive otherwise
Secret Bay isn't a reef — it's a black volcanic sand slope between two headlands where decades of organic debris have created a hyper-productive silt habitat. This is Anilao's signature dive, the one that puts the destination on photographers' bucket lists.
On a single dive here, a good guide can find 20+ nudibranch species, multiple frogfish, mantis shrimp, Bobbit worms, ghost pipefish, seahorses, and octopus. The flamboyant cuttlefish (Ascarosepion pfefferi) is a regular — the only cuttlefish that walks on the seafloor using its lower arms. The mimic octopus (Thaumoctopus mimicus) appears reliably on the mid-slope sand at 8–12 m. At night, the site transforms: blue-ringed octopus, Ambons scorpionfish, Starry night octopus, and Coleman shrimp emerge.
The trick: enter exactly at slack tide, one hour before high tide. Any current kicks up the fine silt and visibility drops to near zero. Done right, the visibility is still only 3–5 m, but your subjects are centimeters away.
Best season: November–May. Night dives productive year-round. Peak critter density January–April.
Pro tip: Hire a dedicated critter-spotting guide for this site. The difference between a dive where you see 5 species and a dive where you see 30 is the guide. Crystal Blue, Aiyanar, and Casa Escondida produce outstanding macro guides.
2. Twin Rocks
Two pinnacles with Anilao's healthiest coral coverage.
Depth: 5–22 m · Skill: All levels · Entry: Boat (25–60 min) · Current: Calm, slight
Two submerged pinnacles side by side, rising from 22 m to within 2 m of the surface. The coral coverage here is the most vibrant in the Anilao area — branching Acropora, massive Porites, and plate Turbinaria in dense formations that support a surprising diversity of marine life.
A resident hawksbill turtle patrols the east face daily and is so predictable that guides know which rock she'll be resting on. Ribbon eels (Rhinomuraena quaesita) — the blue-and-yellow males and all-black females — are consistently seen in the rubble between the two pinnacles. Spanish dancers, ornate ghost pipefish, and pygmy seahorses on the gorgonian fans at 15–18 m.
The barge wreck at the southeast edge is worth a pass — a rusting hull encrusted with sponges, hydroids, and soft corals that attracts batfish and jacks. Jacks and barracuda cruise the outer edges during current changes.
Best season: November–May. Year-round diving possible. Macro photography best in morning light (sun behind the pinnacles).
Pro tip: Go early. This is one of Anilao's most popular sites and afternoon crowds are real.
3. Kirby's Rock
Seamount dive with black coral trees and pelagic visitors.
Depth: 5–33 m · Skill: Advanced (seasonal currents) · Entry: Boat (~10 min from Eagle Point) · Current: Calm at slack, strong at tide change
A seamount rising from 30 m to within 3 m of the surface off the northeast face of Caban Island. The feature here is the black coral trees (Antipathes) that grow in dense thickets along the decline to 30 m — a habitat that's increasingly rare across the Philippines.
On a typical dive, you drop on the shallow plateau at 5–8 m where the coral is diverse and the anthias schools are thick. As you descend the slope, the landscape shifts from hard coral to gorgonian sea fans to the black coral forest below 20 m. Schooling jacks and giant trevally are regulars. Occasional thresher sharks at depth during the cooler months.
The shoreward side drops to 5 m then slopes gradually — a safer route if the current is running. Snorkelers should choose slack water. Visibility reaches 30 m on the best days.
Best season: November–May. Strongest currents during full moon periods.
Pro tip: Dive this site at neap tide only. Spring tides push 2+ knot currents that make this an uncomfortable drift rather than a dive. Discuss tide tables with your operator.
4. Cathedral Rock (Cathedral)
Anilao's most famous site, crowned by a coral-encrusted cross.
Depth: 5–30 m · Skill: Beginner (Open Water) · Entry: Boat · Current: Calm, can have strong currents at neap tide
Two large seamounts rising from 30 m to the surface, split by a narrow channel. A stone cross sits at 15 m, planted by Philippine President Fidel V. Ramos in 1983 and now completely encrusted in coral. The cross has become a pilgrimage marker for Filipino divers.
The fish density here is the highest of any Anilao site. Decades of fish-feeding (now discouraged but the habit persists) have conditioned angelfish, butterflyfish, triggerfish, Moorish idols, surgeonfish, and parrotfish to approach divers closely. Moray eels and nudibranchs inhabit the crevices between the two seamounts. The shallows at 5–8 m are excellent for beginner divers and wide-angle photography.
Cathedral is also the site of the "Son of Cathedral" — a smaller seamount just south where healthy gorgonian fans host pygmy seahorses at 14–18 m.
Best season: Year-round. Most consistent conditions November–May.
Pro tip: Best in early morning when the light enters the channel between the two seamounts, illuminating the cross from above. This is Anilao's most photographed composition.
5. Ligopo Island
The dive guides' personal favorite.
Depth: 10–35 m · Skill: Intermediate · Entry: Boat · Current: Mild–moderate
A wall dive on a small island off Tingloy. The wall slopes gradually from 10 m to a pinnacle at 35 m, covered in gorgonian sea fans, barrel sponges, and a distinctive pink soft coral that blankets entire sections of the wall like a carpet.
Pygmy seahorses (Hippocampus bargibanti) are reliably found on the gorgonian fans at 18–22 m — the guide will know exactly which fan to check. Tiny colorful nudibranchs, red-toothed triggerfish, hawksbill turtles feeding on soft coral, and schools of sardines. The wall at 25–30 m is where the larger pelagics show: barracuda, jacks, and the occasional eagle ray.
This is the site that guides mention when you ask them for their personal favorite. It's consistently productive, photogenic, and visited less frequently than Twin Rocks or Cathedral.
Best season: November–May. Protected from SW monsoon.
Pro tip: Position yourself at the wall edge at 20 m and watch the blue water for 5 minutes — the open-water fish come through in pulses.
6. Sepoc Wall (Sepok Wall)
Anilao's true wall dive.
Depth: 15–30 m · Skill: Intermediate–Advanced · Entry: Boat (~15 min) · Current: Medium, can get strong
A vertical limestone wall west of Sepok Point, dropping from 15 m to 28 m with no gradual slope. The wall is dense with barrel sponges, gorgonian sea fans, and soft corals. The shallow section (~5 m) above the wall has coral gardens.
The wall face at 18–25 m is the zone for pelagic encounters: turtles, occasional barracuda, and schooling fusiliers over the edge. The deep sand slope below 28 m is less visited but sometimes turns up blue-spotted stingrays and garden eels.
Visibility on the wall averages 20–30 m during the dry season — some of the best in Anilao — because the current sweeps the wall clear.
Best season: November–May. Watch the current — cancel the dive if it's beyond 1.5 knots.
Pro tip: Ask your guide to do the wall as a drift. Your boat drops you upcurrent at the south end and you ride the current north along the wall face for 35–40 minutes. The boat picks you up at the north end.
7. Beatrice Rock
Drift diving with swarming anthias and strong currents.
Depth: 10–27 m · Skill: Advanced Open Water · Entry: Boat · Current: Strong tidal currents — dive at slack
A rock outcrop off Maricaban Island's north coast with mixed hard and soft coral coverage. The feature that makes Beatrice worth the current negotiation: swarming anthias that blanket the reef face in a moving cloud of orange and pink. The density of the anthias school here is unmatched in Anilao.
Barrel sponges at 15–18 m. Trevallies and barracuda on the outer edge during tidal flow. The swim-throughs at the base of the rock are worth exploring — they cut through the outcrop and you emerge on the quieter side.
Beatrice is not a beginner site. The current requires negative entry, reef hooks, and the ability to navigate a drift profile. The operator should brief the current direction and your exit route before splash.
Best season: November–May at neap tides.
Pro tip: This is a wide-angle lens site, not macro. Leave the diopter at the resort.
8. The Pier Night Dive
Classic pier pilings muck dive — best at night.
Depth: 3–12 m · Skill: Beginner (excellent night dive) · Entry: Shore/Boat · Current: None to very mild
Anilao village pier — concrete pilings over a sand and silt bottom. The structure has been here for decades and the marine life has adapted completely. Under the pilings by flashlight is the habitat for some of the most sought-after nocturnal species: Bobbit worms (Eunice aphroditois), which are large ambush predators that take over the sediment between the pilings. Coconut octopus, blue-ringed octopus, mimic octopus, stargazers, scorpionfish, and uncommon nudibranch species.
The Pier is shallow enough for Open Water divers with good buoyancy. The silt bottom is easily disturbed, so frog kicks and careful fin placement are essential.
Best season: Year-round night dive. Calm all year.
Pro tip: Enter at least 15 minutes before sunset. The transition between day and night marine life in the first 15 minutes of dark — as diurnal fish settle and nocturnal hunters emerge — is the most productive window of the dive.
9. Basura Muck
The site named after trash — delivering some of Anilao's best macro.
Depth: 5–15 m · Skill: Beginner–Intermediate (good buoyancy required) · Entry: Boat · Current: Mild
"Basura" translates to "trash" in Filipino, and the site looks it: construction debris, pipes, and discarded objects on a sandy slope. In muck diving, debris is prime habitat. Giant frogfish (Antennarius commerson) are the stars here, sitting on concrete pipes and debris at 8–12 m in multiple color morphs. Coral-banded pipefish (Doryrhamphus dactyliophorus) in the interstices. Mantis shrimp in burrows, nudibranchs across the slope, and the occasional dragonet or stargazer.
The disadvantage: boat traffic. Basura is close to the resort strip and boats transit overhead. The guide should deploy a surface marker. Watch for boat traffic on ascent.
Best season: November–May. Daytime visibility 5–12 m.
Pro tip: This site is best as a second dive after a deeper reef dive. The shallow depth profile (max 15 m) gives you extended bottom time and your eyes are already adjusted to spotting macro.
10. Blackwater Diving
Deep-sea creatures at the edge of a phosphorescent rig.
Depth: 30 m (descend to light rig) · Skill: Advanced (50+ logged dives) · Entry: Specialized night boat trip · Current: Varies
Blackwater diving is the most unusual experience Anilao offers. A 30-meter LED-lit rig is lowered into deep open water between islands. Divers descend to the rig's bottom at 30 m, hovering in the pitch-black water column next to the glowing line. The light attracts deep-sea larval creatures from the mesopelagic zone — organisms that normally spend their entire lives below 200 m depth, never seen by divers.
The signature species: nautilus, especially January–March during new moon periods. A pair will drift in from the dark, tentacles extended, attracted to the light. Alongside them: larval crabs in translucent shells, larval fish (look like something from science fiction), squid, octopus, and gelatinous organisms (comb jellies, siphonophores) that bioluminesce when touched.
This is not a dive for beginners. 50+ logged dives, prior night dive experience, and excellent buoyancy are requirements. The psychological challenge of hovering in open water at 30 m with no reference but a vertical light line is real.
Best season: January–March (nautilus peak during new moon). Year-round with reduced success rates.
Pro tip: Book with an operator that uses a dedicated blackwater rig, not a large day-boat retrofitted for blackwater. Casa Escondida and Aiyanar both offer proper setups.
Beyond the Top 10
The documented 22 sites include other worthy dives: Coconut Point (one of the Philippines' best muck spots, with frogfish and cuttlefish), Mainit Point (boulders with whitetip reef sharks in a shallow cave), Mapating Cave (deep wall with cavern formations, advanced only), Sombrero Island (coral islet with consistent seahorses and flamboyant cuttlefish), Cokis Point (reliable pipefish and macro subjects), and Bahura (swim-throughs and dense fish aggregations). With 50+ sites across the area, even a 10-day trip barely scratches the surface.
