Overview

Ten and a half kilometres southwest of Alona Beach, a 25 hectare limestone island sits on a reef shelf that ends in walls and steep slopes on every side. Five permitted sites circle it, and no boat leaves without a booked slot. Black Forest on the southeast is the demanding one, a slope to 40 metres with a dense black coral stand at 35 to 45 that most divers never reach. Cathedral holds the north point, all overhangs and gaps lit through the fissures on a bright day. Rico's Wall takes the west side in front of the island's resort, with giant clams in the sanctuary shallows. Diver's Heaven on the northeast is the seagrass side, where green turtles graze in water shallow enough to snorkel. Rudy's Rock, southwest, sees the fewest boats.

Bigeye trevally circling in a column is what sells the island, and it turns up at four of the five sites. The quota puts fewer divers on the island; it does not spread them around it. In swell the wind pushes every boat onto the same leeward pair. Hard coral at the north point is good across about 50 metres of reef, with tabling acroporas two and three metres across and anchor scars through them. Past the buoys the coral died in the December 2021 typhoon and had not come back by 2025.

Planning your visit

Your dive shop books Balicasag; you do not. It needs both sides of your certification card and a deposit before it can apply, and the town works through applications in the order they arrive. Nothing is sold on the beach on the day. Tickets can be held only three months ahead.

The cap is 60 dives per site per day1, 300 dives across the permitted five2, which shops run as about 150 divers on two dives each. Two is a hard ceiling, so a third dive happens back on the Panglao side. Certified divers only, with no introductory dives and no courses. You do not choose your site either. The booking system hands out a site, a date and a time3.

The island charges its own environmental fee, higher than the 100 pesos on Panglao's reefs: 250 pesos per diver per day, the same figure every source has quoted since 2015. No schedule publishes it, so confirm the amount with your shop along with what else the trip price covers. December to May is the settled window for visibility, and December fills first. Between June and October the southwest monsoon lengthens the crossing and can leave only the sheltered sites diveable.

Geology & underwater terrain

A flat, roughly circular limestone island of 25 hectares, ringed by a fringing reef shelf that runs from about 3 metres down to 6 or 18 metres before it ends. On every side the shelf breaks into near-vertical walls and steep slopes that continue well past recreational depth, with small caverns, ledges and overhangs cut into the west and north faces and sandy, seagrass-covered patches on the shallow northeast shoulder.

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: Every one of the five sites is a wall or a steep slope with no floor inside recreational range. The west face is described continuing past 60 metres, and the black coral at Black Forest starts at 35.Agree a maximum depth on the boat, watch no-decompression time on the deeper faces, and read every published maximum as the depth an operator turns divers around at.
  • Current: Currents run from nothing to moderate and change by site. Black Forest is dived into the current before it turns and drifts, and Cathedral and Diver's Heaven can both pick up.Follow the guide's entry direction, carry an SMB for a drift finish, and keep low over the sand on the first half of Black Forest.
  • Surface and boat traffic: In swell the whole day fleet is pushed onto the same two sheltered sites and most shops leave and descend at the same time, so several boats work one mooring at once.Deploy an SMB before surfacing, surface at the mooring line and not in open water, and let your guide time the entry away from the pack.
  • Marine life: Titan triggerfish are territorial and aggressive in May, June and July, and they nest on the shallow reef tops the dives finish over.Give a nesting triggerfish a wide berth horizontally, keep fins between you and the fish, and do not ascend to escape one.
  • Remote location: The island has no dive infrastructure to fall back on and the provincial hospital is in Tagbilaran City, across the water and the bridges. No working recompression chamber is confirmed anywhere on Bohol: as of February 2025 the country had three, at the Lung Center in Manila, at Mandaue City on Cebu and at Puerto Princesa in Palawan8. The nearest to Balicasag is the Cebu one, roughly 90 kilometres north across the strait, which is a ferry or a flight and not a drive.Carry insurance with hyperbaric cover, confirm the chamber position with your shop on the day, and know the numbers before the boat leaves: Gov. Celestino Gallares Memorial Medical Center in Tagbilaran on (038) 411-4868 and 411-4869, and the coast guard station at Barangay Tawala on Panglao on 0927-350-5484.

Frequently Asked Questions

How many divers are allowed at Balicasag each day, and who sets the limit?

Sixty dives per site per day is the underlying figure, and with five permitted sites that comes to 300 dives in total. Dives, not divers: shops run it as about 150 people taking two dives each. The limit belongs to the Municipality of Panglao, which adopted a carrying-capacity protocol in 2014 on the recommendation of its own environmental protection committee, and it is enforced through tickets and a booking system, with no numbered diving ordinance behind it. Municipal Ordinance No. 08 of 1998, which is sometimes attached to Balicasag, created the island's fish sanctuary and sets no dive cap at all.

How far ahead do you have to book Balicasag, and can you turn up on the day?

You cannot turn up. Reservations on the day are refused, and a boat without existing bookings is not allowed to sail. Your dive shop applies for you and needs a copy of both sides of your certification card plus a deposit before it can, and the local government works through applications in the order it receives them. Shops can only hold tickets three months ahead of the dive date, so anything booked earlier than that is provisional. Two weeks is the usual lead time in high season, a month around the Chinese holidays, and December is the hardest month of the year to get a slot.

Do you get to choose which Balicasag site you dive?

No, and it is not a draw either. The booking system gives a diver a dive site assignment at a specific date and time, so the site arrives with the slot. Allocation between shops is first come, first served, in the order the local government receives the applications, which is also why a shop that applies late finds the day already full. Weather then overrides all of it: in swell the fleet ends up on the sheltered sites whatever was booked.

What do you pay at Balicasag on top of the dive price?

An environmental fee of 250 pesos per diver per day, higher than the 100 pesos charged on Panglao's own reefs. Every source quotes the same number and has done since April 2015, which is unusually consistent for a Philippine user fee and long enough that a rise would not be a surprise. What is missing is a published schedule, so confirm the current amount rather than assume it. One shop lists 400 pesos as a Balicasag sea entry charge; that reads as a per-boat line and not a second diver rate. A camera has been quoted at 250 pesos a day across the same period. Ask whether both sit inside your trip price, and carry pesos in cash.

Can you do more than two dives at Balicasag in one day?

No. Two dives per diver per day is a hard ceiling, and it is why the 150-diver figure and the 300-dive figure describe the same rule. Three-dive trips exist, but the third dive happens on the Panglao side on the way home, usually on a reef near Alona. Night diving is not part of it either: the boats run from about eight in the morning to mid-afternoon, and no shop sells a night dive at the island.

Can an Open Water diver dive Balicasag, and can you learn to dive there?

Open Water covers all five sites, and it is what the great majority of the daily quota holds. Learning is a different answer: introductory dives and training dives have been banned at the island since the 2014 protocol, so a course has to happen on Panglao. What Open Water does not cover is the deep half of the island. Every site is a wall or a slope with no floor inside recreational range, and the black coral that names Black Forest sits at 35 to 45 metres, which is an Advanced or Deep dive and not a first-week one.

Is Balicasag too crowded to be worth it?

That depends on the weather more than on the quota, which is the part the numbers hide. On a calm day the boats spread across the five sites and divers come back describing turtles in the shallows and jacks over the slope. In a 1 to 2 metre swell, wind and current push everyone onto the same two leeward sites, most shops leave and descend at the same time, and divers who went in 2025 and 2026 describe chaos on the surface and underwater; one cut a four-day Balicasag booking short after a single day. Snorkelling and diving are also not the same product here. Diving is rationed and permitted; snorkelling is not monitored, and the angriest accounts of the island come from the surface and not from the water.

Which sites should you pick if you only get two dives?

Mostly you do not pick, because the booking system assigns the site. If your shop can express a preference, the five split cleanly. Black Forest for the slope, the schooling jacks and the only current worth planning around. Cathedral for the overhangs and the light through the gaps. Rico's Wall for the no-take shallows and the calmest water on the island. Diver's Heaven for the shallowest profile of the five and resident turtles on the seagrass, which is where nervous or newly certified divers get taken. Rudy's Rock for the fewest boats. Note that calmest and easiest are two different sites here: Rico's Wall has the lowest current rating and Diver's Heaven the shallowest dive.

What is the difference between Rico's Wall and the Marine Sanctuary?

For anything you can book today, they are the same dive. The west side of the island fronts the Balicasag Island Fish Sanctuary, a 3.44 hectare no-take zone established in 1998, and the wall running along it is called Rico's Wall by some shops and the Marine Sanctuary, or just the Sanctuary, by others. Shops overwhelmingly use one or the other and seldom both. The name began as a label for the stretch of coast in front of the no-take zone and not for a single entry point, which is why older accounts sometimes attach it to the neighbouring Rudy's end instead. Rudy's Rock is a genuinely different site a few hundred metres to the southwest, with its own entry point, its own current pattern and a large rock marked by a stick that shows above the beach at low tide. A fifth name, Royal Garden, is in live use and unsettled: some lists equate it with Cathedral and others place it where Diver's Heaven sits.

When is the best time of year to dive Balicasag, and what does the monsoon change?

December to April or May is the settled window for conditions and visibility, and it is also when the island is busiest and slots go first. From roughly June to October the southwest monsoon reshapes the day without cancelling it: the Alona boats moor further west at Doljo, the crossing stretches past an hour instead of half of one, and swell can leave only the sheltered northeast sites diveable, which is exactly when the whole fleet lands on the same two spots. October and November are the quieter shoulder. Water sits between 26 and 30 degrees all year, and a 3 mm full suit is the local norm.
