Lighthouse

Also known as: Cabilao Lighthouse, Lighthouse 1, Lighthouse Cabilao, Lighthouse West

Seagrass, sand and coral boulders under Cabilao's lighthouse headland, worked slowly for sea moths, stargazers and ghost pipefish.

Last updated August 2026

The dive

You get in over seagrass, and there is a lot of it. It runs out from the beach in beds with sand between them, and coral boulders sit in the sand furred over with soft coral. The looking is slow. Guides work the open patches for sea moths, for ghost pipefish, for shrimps tucked into anemones, and for the stargazers that lie buried with nothing above the surface but their eyes.

Green turtles are ordinary here. So are banded sea kraits, which come up through the beds and pay nobody any attention.

At about a hundred yards the flat runs out and the corals go over an edge. How far down they carry on is the one thing about this dive that has never been settled, and it may depend on which of the two Lighthouses your guide has brought you to. Ask on the boat.

After dark the same ground becomes a muck dive.

What makes it special

Cabilao sells walls. The diving here happens in the top ten metres of water, over ground you can hang above for an hour without touching anything or running short of gas, and that inverts what the island is known for. Sea moths, stargazers, ghost pipefish and snake eels are what people come to find, and the finding is the dive.

The trade-off is honest. There are no big animals in it, no schooling fish, no landscape shot. What you get instead is an hour of looking at things four centimetres long, with a turtle passing through now and then, on the one piece of Cabilao where nothing is trying to pull you deeper.

History and origin

Punta Baluarte has been a lookout for centuries. The headland carries the foundations of a Spanish watchtower, a working modern light, and a Spanish-era lighthouse that stood derelict until a conservation grant paid to restore it. The bargain behind the grant was explicit. The island's villages added fifty acres of water to their two no-take zones and committed them for twenty years, and the lighthouse was rebuilt in return. It reopened in May 2011 and holds a small museum. Some of the water in that trade is the water you dive.

The site carries a second history that people are still selling. Divers were coming to this island for scalloped hammerheads all through the 1990s. This corner is where the winter shark claim was first written down, by somebody who dived here and saw them. They were reported fished out around the turn of the century, and nothing dated has been recorded at Cabilao since. The sentence outlived the sharks by twenty years.

Photographer's notes

Come at night. The seagrass and sand read as empty at midday, and after dark they turn into muck ground: stonefish out in the open, mantis shrimp at their burrows, stargazers buried flat with only the eyes clear of the sand. That last one is the set piece. It is a low-angle shot and a patient one, and locating the animal takes longer than framing it.

By day the work is macro at snorkel depth. Depth is not the constraint here and neither is gas, so an hour can go on one patch of seagrass. Wide angle has nowhere much to point except the edge, and the edge is not why anyone comes.

Know before you go

Ask which Lighthouse you are being taken to. Operators run this stretch as two dives on different ground a few hundred metres apart, and what you get told about the site beforehand may belong to the half you are not diving.

Depth is the thing to settle before you get in. A government report singles out the ledges around this island as water where the current leaves divers uncertain of their own depth and below open-water limits without noticing1. This site publishes no maximum, so bring your own.

A no-take zone lies in this part of the island and one of the two is reported closed to diving outright. No map of the boundaries exists in public, so the guide's line is the only version you have.

Stay off the bottom. Stonefish and scorpionfish sit motionless in exactly the sand a guide is searching, and a fin dropped into the seagrass costs the habitat this dive depends on. An older account from this site describes a guide feeding a fish to a mantis shrimp to draw it out. If that is offered to you, decline it.

Nothing on this island treats a bend. Bohol has a hyperbaric chamber and it does not belong in your plan: it was reported sitting unused over at Panglao in April 2023, and the resolution that was meant to fund the repair had been passed ten days earlier1. The island sits inside the municipality of Loon, whose district hospital carries the name Congressman Natalio Castillo Sr. Memorial Hospital, out at barangay Canhangdon. The building meant to replace the one the 2013 earthquake took was still unfinished when it was last reported on, in March 2023, and what it can handle has never been published2. Anything serious goes to Gov. Celestino Gallares Memorial Medical Center, over in Tagbilaran City, and getting there means a boat off the island plus a stretch of road. Write down DAN Asia-Pacific on +61 8 8212 9242 before the first dive, and confirm your insurance pays for a chamber and for reaching one.

Why Dive Lighthouse

What makes this dive site stand out.

  1. The island's macro ground

    Seagrass beds and sand with coral boulders in them, worked slowly for small animals

  2. Two dives under one name

    Operators run Lighthouse 1 and Lighthouse 2 as separate dives on different ground

  3. Muck diving after dark

    Stonefish, mantis shrimp and buried stargazers on the island's standing night dive

  4. Restored Spanish-era lighthouse

    A Spanish-era light reopened in May 2011 and now a museum stands on the headland

  5. Shallow enough to snorkel

    The reef flat holds around 10 m and the walk north from the resorts takes minutes

Summary

Easy where the dive actually takes place. Two things lift it off easy. The site sits on a headland, which puts moving water over it on days when the rest of the island is still, and the outer edge drops away to a depth nobody has pinned down.

Safety considerations

What can go wrong here, and what divers do about it. Conditions change - take the briefing from the operator on the day.

  • Depth: How deep the ground runs past the outer edge has never been established. A state agency has warned that current over this island's ledges leaves divers unsure of their own depth and below open-water limits before they notice.Fix your own maximum on the boat, because the site does not publish one. Everything a guide will find you sits in the shallow half.
  • Current: The site sits on the island's northwest headland and moving water is reported over it, which is not how the rest of Cabilao dives.Ask at the briefing which way it is running and how the boat will pick you up, and carry a marker.
  • Marine life: Stonefish and scorpionfish lie motionless in the same sand and rubble the guide is searching, and stargazers are buried in it with only the eyes showing.Stay off the bottom and hold trim over the beds. Nothing here needs to be touched to be seen.
  • Site rules: A barangay no-take zone lies in this part of the island, and one of the island's two is reported closed to diving outright. No map of the boundaries has been published.Follow the guide's line and do not wander off it here.
  • Remote location: Recompression is not available on this island, and Bohol's own chamber was reported out of service at Panglao in April 2023, so no chamber belongs in a plan made here. Getting to hospital starts with a boat off Cabilao, and the public crossings finish about six.Shallow profiles, which this site makes easy. Insurance has to cover a chamber and the journey to one, and the numbers belong on paper before the boat leaves the beach.

Frequently Asked Questions

How deep is Cabilao Lighthouse?

Nobody can tell you honestly, and this page publishes no maximum for that reason. Two descriptions of this site have been in circulation for twenty years and they do not describe the same dive. One line of accounts calls it a wide seagrass slope in about 20 m of water, with the shallow flat snorkelable at around 10 m and an edge a hundred yards out. The other calls it a wall to 25 m, a plateau at 30, and another wall below that. Both are first-hand. The likeliest explanation is that they are describing two different pieces of ground under one name, since operators split this stretch into Lighthouse 1 and Lighthouse 2 and run them as separate dives. That is an inference and nothing published confirms it. What would settle it is a second operator's site list, or one dated dive log, giving a depth for a named half of the site. Until that exists, ask which of the two dives you are on and set your own floor before you get in.

Is Lighthouse 1 the same dive as Lighthouse 2?

No. Two published site lists put separate pins on them, a few hundred metres apart, and divers who have been here log their dives under the numbered names. The shallow seagrass and sand half is the one every description agrees on and it is what most groups get. The other half is where the wall descriptions come from. This matters more than it sounds: what you are told about the site before you get in may belong to the piece of ground you are not diving. Ask which one the boat is going to, and ask what the deepest part of it is.

Are there hammerheads at Cabilao Lighthouse from December to April?

No. That season is real as a piece of history and dead as a plan. Scalloped hammerheads were real at this island in the 1990s, and this corner is where the winter claim got written down in the first place, by somebody who dived here and saw them before 2003. They were reported fished out around the turn of the century, and no dated sighting has been recorded at Cabilao since. Everything selling the season today descends from that one observation, copied forward for two decades without anybody checking whether it still held. One version of the copy puts the sharks at 40 to 45 m, which is worse than wrong: it hands a diver a depth target on a site whose depths are not even settled. Come for the small animals, which are still here.

Is Cabilao Lighthouse worth doing as a night dive?

It is the best night dive on the island and the one the site is really for. Seagrass and sand that read as empty in daylight fill up after dark: stonefish out in the open, mantis shrimp at their burrows, stargazers buried with only the eyes clear. The profile helps as much as the ground does, because the shallow half means an hour underwater without any of the gas or depth arithmetic the island's walls need. It also needs you to be staying here. Day boats coming over from Panglao or Cebu leave in the afternoon, so the night diving belongs to whoever sleeps on the island.

Can you snorkel at Cabilao Lighthouse?

Yes, and the shallow half of this site is one of the few places on the island where snorkelling and diving genuinely see the same thing. The reef flat runs at around 10 m at its deepest, the seagrass and coral boulders start close in, and green turtles and sea kraits are both routine in that depth. Getting there on foot is a walk of three or four hundred yards north along the beach from the resorts, with entry off the sand in front of the lighthouse. A snorkeller loses the small stuff. Sea moths and buried stargazers take a guide, a slow pace and usually a torch.

What condition is the coral in after Typhoon Odette?

Damaged in the shallows and not surveyed since. Two people have described this site after the December 2021 typhoon, two years apart. Photographs taken here in August 2023 came with the observation that the corals were partly damaged while the fish, invertebrates, turtles and sea kraits were still there in numbers. A diver working the island in August 2025 described the shallow ground as mostly rock and rubble. Neither is a survey and neither was making a general claim about the island, but they point the same way. The seagrass and sand this dive is built on came through better than hard coral would have, which is part of why the macro is still worth the trip.
