Mabinay, the cave country in the middle of Negros
Mabinay is the town almost everyone crossing Negros passes through and almost nobody stops in. It sits inland in the mountainous middle of the island, on the provincial highway that links Negros Oriental to Negros Occidental, which makes it the halfway mark of the long Bacolod-to-Dumaguete drive - and, under its own fields, one of the great cave systems of the Philippines.
The local nickname is cave town, and the numbers behind it are real. More than a hundred caves are documented in the municipality, local counts run past four hundred, and a Belgian and Dutch survey team identified and mapped around fifty of them. Odloman Cave, at 8,870 metres, is on record as the second-longest cave system in the country.
That does not mean you need ropes and a wetsuit. The caves people actually visit are the Bulwang group, a short ride from the town centre, where three of them have steps, walkways and daylight coming through the roof. They are the sort of place you can see properly in a couple of hours in ordinary shoes.
The confusion worth clearing up first: Mabinay is not Mambukal. Mambukal is the hot-springs resort in Murcia, up in Negros Occidental behind Bacolod. Mabinay is the cave town in Negros Oriental, in the centre of the island. The names look alike, they are on opposite sides of a mountain range, and travellers mix them up constantly.
How to get to Mabinay
- As a stop on the cross-island drive (what we arrange)adds ~2-3 hrs to the crossing
This is the one that makes sense. The Bacolod-to-Dumaguete run is about six hours whatever you do, and Mabinay is roughly its midpoint - so instead of a service-station break you spend a couple of hours underground and carry on. Same driver, same car, luggage stays with you. Cave guides and entrance fees are paid locally.
- Day trip from Dumaguete~2 hrs each way
A private car from your Dumaguete hotel, with your driver waiting while you do the caves, and back the same day. It is a long way for one sight, so it suits travellers who genuinely want the caving rather than a box ticked.
- Ceres bus (public)~2 hrs from Dumaguete
The Ceres services routed via Mabinay - the fast six-hour crossing between Dumaguete and Bacolod - all stop at the town terminal, so Mabinay is easy and cheap to reach. Check the signboard actually says Mabinay: Ceres also links those two cities via Bayawan and via San Carlos, and neither of those comes near the place. From the terminal you still need a tricycle out to Bulwang, and you are on the bus timetable for the trip back - which is what catches people out on a day trip.
What to expect
The Bulwang Caves
The visitable cluster, in Barangay Bulwang - "bulwang" means big hole - about a twenty-minute tricycle ride from the Mabinay bus terminal. Three of its caves are open to complete beginners, and guides are arranged at the site rather than booked ahead.
Panligawan, the courting cave
Named from the local word ligaw, to court - this is where couples were once brought. A flight of stone steps takes you down, and daylight drops through a hole in the dome-shaped roof into the chamber. It is the photograph everyone comes away with.
Pandalihan, the marriage cave
Shallow, easy to enter and needing no special equipment, with wedding rituals once held under its open main hall. Look for the swiftlet nests in the roof, and the millipedes - harmless, but they reach 25 cm and squirt a purple liquid that stains if you disturb them.
Crystal Cave
The prettiest of the accessible three, 157 metres long and 12 metres deep, with stalactites and stalagmites throughout. The municipality built a raised walkway through it, so you stand above the cave floor rather than on it. It is a living cave: touching the formations discolours them, and guides will show you where visitors already have.
Odloman and Cayaso, for experienced cavers only
Odloman runs 8,870 metres, the second-longest system in the Philippines, entered either by swimming an underground river or through a hole in its roof. Cayaso is the ninth longest at 2,222 metres, with a subterranean river running through its main hall. Both are serious trips for equipped, experienced cavers - not add-ons to a transfer.
Mabinay Spring
A natural spring in the heart of the town, three to five minutes from the centre, used for swimming and kayaking and also the town’s main water source. Folklore says it is fed by the tears of Binay, a chieftain’s daughter whose lover her father had killed, and that the town took her name.
Best time to visit
Caving in Mabinay runs all year. Being inland and high, the town is a little cooler than the coast, and mornings are the best of it - you want daylight coming through the roof openings at Panligawan, and you want time to get back. Wear shoes you do not mind ruining; cave floors are wet and uneven whatever the weather is doing outside.
Mabinay: frequently asked questions
How do I get to Mabinay from Dumaguete?
Mabinay is about 87 km north-west of Dumaguete, roughly two hours by road. Ceres buses to Bacolod routed via Mabinay - not every Bacolod service is, so check the signboard - stop at the Mabinay terminal, and from there it is about a twenty-minute tricycle ride out to the Bulwang caves. A private car with a waiting driver removes both the timetable and the tricycle, and we quote a fixed fare for it.
Can we stop at the Mabinay caves on the drive between Bacolod and Dumaguete?
Yes, and it is the way we would suggest doing it. Mabinay sits near the midpoint of the roughly six-hour cross-island route, so the caves are already on your road. Tell us when you book and your driver builds in the stop - a couple of hours at Bulwang, luggage staying in the car - instead of a plain service break. Cave guides and entrance fees are paid at the site.
Do you need caving experience to visit the Mabinay caves?
Not for the three at Bulwang. Panligawan and Pandalihan are shallow, with stone steps and open roofs, and Crystal Cave has a built walkway through it - no equipment beyond sensible shoes, and a local guide goes with you. Odloman and Cayaso are a different matter entirely: those need real caving experience and gear, and Odloman is entered by swimming an underground river or dropping through the roof.
How many caves are there in Mabinay?
More than a hundred are documented and local counts go past four hundred, of which a Belgian and Dutch survey team identified around fifty. Only a handful are set up for visitors. Odloman, at 8,870 metres, is recorded as the second-longest cave system in the Philippines and Cayaso, at 2,222 metres, as the ninth.
Is Mabinay the same as Mambukal?
No, and it is the most common mix-up on this island. Mambukal is a mountain resort with hot springs and a waterfall trail in Murcia, Negros Occidental, about an hour from Bacolod. Mabinay is a cave town in Negros Oriental, in the centre of Negros, about two hours from Dumaguete. Different provinces, different sides of the mountains, roughly four hours apart.
How much does it cost to visit the Mabinay caves?
Guide fees and cave entrance charges are paid locally at Bulwang and are set by the barangay, so we do not publish figures that go out of date. What we quote is the transport - a fixed price for the private car, whether that is a day trip from Dumaguete or a stop built into your cross-island transfer.
