Sumilon Island and Sandbar: The Sandbar That Moves

Sumilon is a small wooded island off Oslob with two ways in: the public sandbar, by a hired boat for about ₱1,500, or the Bluewater resort that leases most of the island, on a day pass. Its reef was the first marine reserve in the Philippines, set up in 1974, and fifty years of being protected, opened and protected again made it one of the best-studied reefs anywhere. The crossing from Bancogon takes 15 to 30 minutes.

Most people do it the same morning as the Oslob whale sharks: Tan-awan and Bancogon are neighboring barangays, a short drive apart, not a boat ride.

The sandbar that moves

The sandbar changes shape and position around the island through the year, and the tide decides how much of it is out of the water. More sand shows at low tide; check a tide table before you choose your crossing. It has no shade.

The public sandbar and the sanctuary around it are run by the Bangcogon Oslob Fishermen Association for the town, with the fees shared between the municipality, the barangay and the association. The resort does not manage it. The sandbar is closed for cleanups on some Wednesdays; sources disagree on whether it is every week or once a month, so ask at the port.

Sumilon fees and boats

Item	Price	Notes
Public boat from Bancogon	₱1,500	Per boat, about 10 people

A new sanctuary management plan for 2026 to 2030 raises the fees, cuts the daily visitor cap to 500 and adds no-anchor zones. Which parts are in force yet could not be confirmed online; check at the Bancogon port.

The Bluewater day pass

Bluewater Sumilon leases 17 of the island’s 24 hectares. Its day pass runs from 8 AM to 3 PM with the resort boats from its own pier in Bancogon. In 2025 listings it included the pools (the infinity pool only until noon), the beach and sandbar, a mask and snorkel, kayaks and pedal boats in the lagoon, and a guided trek; weekdays came with food credit and weekends with a buffet lunch. Prices differ by seller, so book with the resort directly.

The first marine reserve in the Philippines

In 1974 Silliman University’s marine laboratory, led by Angel Alcala, persuaded Oslob to close part of Sumilon’s reef to fishing. When protection broke down in the mid-1980s and fishing resumed, dynamite and muro-ami nets reduced parts of the reef to rubble and the big predatory fish vanished. Protection returned in the 1990s; by 1999 large predators were back to their old size, and catches outside the reserve were about 30% higher. The lesson Alcala drew, that communities have to manage their own reserves, shaped Apo Island and much of what followed. He received the Ramon Magsaysay Award in 1992 and died in 2023.

Typhoon Odette damaged the shallow coral gardens in 2021, and a 2025 assessment found new coral growing back. The sanctuary now covers about 40 hectares. Blacktip reef sharks use the shallows around it.

What else is on the island

• The lighthouse. On the south side, in a protected stand of trees, next to the ruins of a 19th-century watchtower built against raiders.
• The caves. Natural caves where fishermen once sheltered. Stories of hidden treasure are local legend.
• Snorkeling and diving. The reef wall off the island is a known dive site; sanctuary fees apply.

How to get to Sumilon

• From Cebu City. About 125 km, three to four hours south by car, longer by Ceres bus from the Cebu South Bus Terminal. Get off at Bancogon, Oslob.
• From the whale sharks. Tan-awan is the next barangay; a short ride by tricycle or car.
• The crossing. 15 minutes in calm weather, up to 30 in the rainy season.
• Bring. Cash, water and sun protection. Do not collect shells or coral; it is a marine protected area.

The drawbacks: the public sandbar has no shade or facilities, the resort day pass is the comfortable option and priced like it, the fees are in transition, and the sandbar can be closed on a cleanup Wednesday.

Near Sumilon

Tumalog Falls is minutes from Tan-awan. In Oslob town, the Cuartel is a Spanish barracks left unfinished, and further round the coast are Inambakan and Aguinid. Oslob is also the crossing point for the boats to Siquijor.

Sumilon is the place that showed a protected reef pays back the fishermen around it. The Protect What Lies Beneath tee is for exactly that.
