Wahig River

Overview

Wahig River forms the upper tributary of the Wahig-Inabanga River System and Watershed, one of Bohol’s more ecologically significant drainage systems. It rises in the mountains of Sierra Bullones and runs through Danao and Pilar before joining the Inabanga River, which continues north to the Bohol Sea. Downstream, the Wahig’s waters — with the Pamacsalan River, a sister tributary rising in the same mountains — flow into an irrigation reservoir behind the Pilar (Malinao) Dam before reaching the Inabanga, per Wikipedia’s entry on the Inabanga River (accessed 2026-08-28), making the river a working piece of agricultural infrastructure for central Bohol as much as an adventure corridor. Past its role as a freshwater source, the upper river also functions as an adventure corridor for kayaking, tubing, and organized river trekking.

The mountains where the Wahig rises also carry an older history than the river’s current ecotourism branding: Bohol’s interior highlands, Sierra Bullones’s ridges among them, served as a natural refuge zone during the Dagohoy Revolt of 1744–1829 — an 85-year uprising against Spanish rule and the longest-running revolt in Philippine colonial history.

Location

Sierra Bullones, Bohol, with the river corridor extending through Danao and Pilar municipalities. Sierra Bullones is in the central upland zone of Bohol, approximately 45 km east of Tagbilaran City via the Trans-Central Highway.

Getting There

From Tagbilaran City, take a bus or van along the Trans-Central Highway toward Candijay or Carmen — Sierra Bullones is roughly 1.5 hours by road. The Sierra Bullones Municipal Tourism Office coordinates river trekking bookings and access, working with the barangay hosting the activity; the documented route runs approximately 10 km from Barangay Danicop to Barangay Canlangit. Arrange access and scheduling through the Municipal Tourism Office rather than at an informal put-in point.

Practical Info

• Activities: kayaking, tubing, and “river trekking” — the last is publicized by Bohol’s official provincial tourism Facebook page as a named activity in Sierra Bullones (“a few hours of adventure”) and is organized as a formal, bookable ecotourism service by the Sierra Bullones Municipal Tourism Office (see Guides below for operator, pricing, and booking details).
• Best water levels: typically after the rainy season tail-off (October–November) when water is high but not flooding; dry season (December–April) lowers some sections
• Guides: Yes. The Sierra Bullones Municipal Tourism Office runs river trekking as a formal, bookable ecotourism service, coordinated with the concerned barangay. Per the municipality’s 2026 Citizen’s Charter, fees are: individual entrance fee ₱50, guide fee ₱600, plus ₱20 for buko/coconut; group bookings add a ₱200 transport fee and ₱100 certification fee.
• Gear: No local equipment rental is documented. The municipality’s official participant checklist requires visitors to bring their own gear — non-slip sandals, comfortable clothing and footwear, extra clothes, a cap/hat, a waterproof bag, drinking water and food, and a first aid kit.

What to Expect

In its upper reaches the river runs through forested upland terrain, flattening into lowland agricultural land as it nears Danao and Pilar. The current carries enough push for kayaking and tubing, making this one of the few inland water-sport corridors on the island outside Loboc. The wider Wahig-Inabanga System is a protected watershed, the freshwater source for a good part of central Bohol.

The municipal tourism office describes the activity as following the riverbed and crossing natural rock formations through hidden countryside sections; the documented trekking route runs about 10 km between Barangay Danicop and Barangay Canlangit. (verify details locally)

Notes

• The Wahig-Inabanga System is a designated watershed area — confirm if any access restrictions apply
• Dompor Farms and River Trekking are also listed as attractions in Sierra Bullones municipality
• Formal coordination is required: bookings go through the Municipal Tourism Office, which coordinates with the concerned barangay and requires Barangay Captain approval before a session is confirmed. Participants log attendance, sign a waiver, and attend a safety briefing before starting, and receive a Certificate of Participation afterward (per the municipality’s 2026 Citizen’s Charter).
• A municipal-profile source (bohol.ph, checked 2026-07-17) confirms the Wahig River’s tributaries are used for irrigation but contains no tourism, guide, or access information. A fresh pass on 2026-07-28 checked the Sierra Bullones LGU’s own official portal (sierrabullones.com) and its 2026 Citizen’s Charter PDF, rather than repeating the earlier general English-language search — this resolved the operator, guide-fee, coordination/permit, and gear questions (see citations below). River width, gradient, and a skill-level breakdown of specific sections remain undocumented in any public source found this round (checked: sierrabullones.com and its tourism/blog subpages, richestph.com, Wikipedia, TripAdvisor search, Google Maps-oriented search, and a Cebuano/Filipino-language search for “Ilog Wahig Sierra Bullones pagsakay pasyalan Bohol”); these details remain unconfirmed.
