Inabanga Mangrove Forests

Overview

Inabanga has the largest mangrove area in Bohol, fed by the province’s longest and largest river running through the municipality. The mangroves line both the Inabanga River banks and the coastline. The ecosystem hosts eco-tours with guided birdwatching, and Inabanga is a documented staging and wintering area for migratory shorebirds — a status shared with the neighbouring municipality of Getafe.

The mangroves carry a documented ecological function: they protect the coastline from storm surge and wave action, prevent riverbank erosion during floods, and serve as nursery habitat for fish, crustaceans, and invertebrates, with their tangled root systems sheltering juvenile marine species. For communities below the poverty line in Inabanga, the mangroves are also a source of housing materials, firewood, charcoal, and poles for fish traps.

Location

Along the Inabanga River banks and coastal areas, Inabanga municipality, northern Bohol. The mangrove forests extend from the river estuary into adjacent coastal zones.

Getting There

From Tagbilaran City, take a bus or van north to Inabanga (approximately 1.5–2 hours). In Inabanga town proper, tricycles run from the bus terminal to the Inabanga Nature Park and Fishing Village entrance, located behind the St. Paul the Apostle Church. Motorised bancas are available at the entrance for river and mangrove tours.

Those arriving via Tubigon port (fast craft from Cebu) can take a vehicle for hire or bus directly to Inabanga.

Practical Info

• Tour type: motorised banca river cruise through mangroves
• Combined offer: Inabanga Nature Park and Fishing Village with fish meal (catch-your-own or standard seafood menu)
• Birdwatching: active staging area for migratory shorebirds (peak migration periods: April–May northward, September–October southward)

What to Expect

The Inabanga River runs wide and deep, its banks lined with tall coconut palms, nipa palms, bananas, ferns, and thick shrubs. Eco-tour bancas travel through the mangrove corridor, where guides point out local and migratory bird species.

Scientific records document significant shorebird activity: in late April 1987, twelve shorebird species were observed between the Inabanga Estuary and Tubigon (survey by John R. Howes and Perla M. Magsalay). In mid-September 1987, over 4,800 shorebirds of 14 species were counted, including Asian Dowitchers.

Mangrove species are diverse and concentrated near the riverbanks. Regenerating species include Acanthus sp., Acrostichum aureum, and Lumnitzera sp. among fish pond boundaries.

After the river cruise, the Inabanga Nature Park and Fishing Village offers a fish meal — either self-caught from the fishpond or from the standard seafood and native dishes menu.

Another point along the river is Macaban Cave, an underwater cave whose entrance sits just above the waterline. Local residents call the area “Macaban City” and associate it with supernatural beings (engkantos).

Notes

• The name “Inabanga” derives from “Inabangan” (Cebuano: rented river), a reference to the belief that the river’s annual crocodile-related fatalities were a form of tribute paid by the community for use of the waterway. Spanish speakers simplified “Inabangan” to “Inabanga.”
• Mangroves here serve dual roles: ecological buffer and livelihood resource for lower-income households
• Conservation pressure: the mangroves are exploited for firewood and construction materials — source narrative calls this a conservation priority
