Balicasag Island Diving

Overview

Balicasag Island is a marine sanctuary approximately 6.5 kilometres southwest of Panglao Island, declared a protected area in 1985. The island is roughly 600 metres in diameter. Its dive environment is defined by vertical walls dropping from a shallow reef shelf — the shelf is 3 to 8 metres deep and 10 to 55 metres wide — into depths exceeding 83 metres on the north and northwest faces. The walls are encrusted with sponges and gorgonians; strong currents along these faces bring pelagic species, including schooling jacks, mackerel, and barracuda.

In December and January, hammerhead sharks are periodically encountered, and whale shark sightings have been recorded. The island’s four principal named dive sites — Cathedral, Diver’s Heaven, Black Forest, and Ruby’s Rock — cover the full circumference of the reef. The Panglao local government limits Balicasag to 150 diver entries per day across two dives, managed through an advance-booking system.

The south and southwest shelf grades more gently to 20 to 23 metres and is covered with wide patches of hard and soft coral interspersed with caves and overhangs sheltering large groupers, Napoleon wrasses, and snappers. The Black Coral Forest at the island’s northern tip is an anomaly: dense black corals growing in unusually shallow water at around 30 metres, typically a species found below 50 metres. Researchers attribute the depth displacement to the combined effect of island shadow, cold upwellings, and nutrient-rich currents.

Location

Balicasag Island, administratively part of Panglao municipality, sits 6.5 kilometres southwest of Panglao Island. The island has a single small settlement with a local community and a resort. Access is exclusively by outrigger boat from Alona Beach or other Panglao departure points, approximately 40 minutes by pumpboat.

Getting There

From Alona Beach, Panglao: outrigger boat transfer approximately 40 minutes. Dive operators on Alona Beach and at Panglao-area resorts run scheduled dive trips to Balicasag; advance booking is required due to the 150-diver-per-day cap. Day trips from Tagbilaran are also bookable through tour operators. Bring cash for the environmental fee collected at the island.

Practical Info

Diver limit: 150 persons per day, two dives maximum, advance reservation required through the Panglao LGU system; each operator is typically limited to one boat of up to 20 divers per day, with slots allocated first-come, first-served. Environmental User Fee (EUF): approximately ₱250 per diver per day, usually collected in advance by the dive operator as part of booking. Guides are required for the marine sanctuary. A surface boat must be on standby during dives at sites with strong currents, particularly on the north and northwest walls. Water temperature ranges typically 27–29°C. Best visibility months are December to April; rainy-season visibility can decline.

What to Expect

Four principal dive site characters:

Cathedral (southwest): A craggy wall with multiple caves and recesses requiring a torch. Schools of big jacks idle in the current. Sunny conditions create light reflections inside the cave formations. Wall starts 30 to 50 metres off the beach in 2 to 3 metres of water.

Black Forest (north tip): Dense black corals at 30 metres depth on a ledge-and-sand substrate. Fish include moorish idols, batfish, lionfish, nudibranchs, and Spanish dancers. Slack tide is essential — strong currents require a pickup boat.

Turtle Point (east): Drop-off at 20 to 25 metres with caves where sea turtles shelter. Cushion stars, feather stars, lionfish, triggerfish, and mackerel on the surrounding walls. Anemones with clownfish in shallower sections.

The Cavern (northeast of resort): Multiple small caves at 20 to 25 metres on the drop-off wall. Best visited near sunset when diurnal and nocturnal species overlap.

The reef top is flat, mostly seaweeds and rock, with sea fans, lionfish, and scorpionfish also present on shallower sections.

• Scuba Diving in Balicasag Island, Bohol, Philippines, accessed 2026-07-17 — confirms Environmental User Fee of approximately ₱250/day per diver, 150-diver daily cap, one boat of up to 20 divers per operator, first-come-first-served slot allocation.

2026-07-28 research round (fresh angle — official LGU/tourism-office and operator-form sources, not dive-shop marketing pages): Searched for a Panglao LGU or Protected Area Management Board (PAMB) contact specifically for direct/public Balicasag dive-slot booking. Found: (1) Panglao Municipal Tourism Office listing, panglaotourism.com, accessed 2026-07-28 — general office contact: +63 38 411 6731, tourismpanglaocentral@gmail.com, Heritage Complex, Anos Fonacier Circumferential Road, Panglao; email corroborated independently by Bohol New Normal Travel Guide, altheasadventures.com, accessed 2026-07-28. (2) The official panglaolgu.gov.ph site returned HTTP 403 to automated fetch and could not be verified directly. (3) Philippine Fun Divers, boholfundivers.com, accessed 2026-07-28, and other operator sites describe a “Comprehensive Dive Reservation Form (CDRF)” — listing each diver’s name, dive level, nationality, and certification — that operators must submit to secure a slot within the 150-diver daily cap; no source specifies which office receives the CDRF, and none of the operator pages list a public LGU phone/email for divers to book directly. Conclusion: the general Tourism Office contact above appears to be for general inquiries, not a confirmed diver-facing booking line, so the specific fact (a direct LGU booking contact/hotline for divers) remains unresolved. Booking-through-accredited-operator remains the only confirmed path. A future pass could try calling +63 38 411 6731 directly to ask whether it routes to Balicasag dive bookings, or check the Panglao LGU Facebook page (facebook.com/panglaoturismo) for a pinned post on the CDRF process.
