Biabas Bat Cave

Overview

Biabas Bat Cave is a natural limestone cave in barangay Biabas, Guindulman, southeastern Bohol, classified under Nature (Caves) in the BPTO provincial tourist-attraction inventory. It hosts an active bat colony, one of several roost caves worked into Bohol’s karst interior.

A 2022 Philippine Information Agency report on the neighboring Eskaya community in Biabas describes a hill called Bud Cambatud in the same barangay where bat caves are worked for guano, used locally as inorganic fertilizer. Whether this is the same cave the BPTO lists separately as “Biabas Bat Cave” isn’t confirmed, but it points to small-scale guano collection as an established practice among bat caves in this barangay.

Location

Barangay Biabas, Municipality of Guindulman, Bohol. Guindulman is on the southeastern coast, approximately 55 km from Tagbilaran City via the Tagbilaran–Jagna–Guindulman coastal road.

Getting There

From Tagbilaran, take a bus or van toward Jagna or Guindulman (roughly 1.5 hours). From Guindulman town proper, hire a habal-habal to barangay Biabas. [TO ENRICH: exact travel time from Guindulman poblacion to the cave trailhead]

Practical Info

• Local guide recommended; arrange through the barangay
• [FACT NEEDED: entrance fee or guide fee, if any]
• Bring a headlamp and closed-toe footwear

What to Expect

Bat caves in Bohol typically stage a daily exodus at dusk — the colony exits the entrance in a visible stream, a display you don’t need to enter the cave to see. Interior conditions vary cave to cave, but low ceilings and guano-covered floors are the norm across the province’s bat roosts.

Notes

• [FACT NEEDED: cave-specific dimensions, bat species, and commercial guano use not found in any independently verifiable source as of this research pass]
• Guindulman also hosts Basdio Marine Sanctuary and the Eskaya cultural site — viable for a combined itinerary
• 2026-07-28 research pass (fresh angle, no new facts found): checked source types not covered in the prior pass — (1) the official Municipal Government of Guindulman tourism destinations page, guindulman.net/destination, accessed 2026-07-28, which lists Basdio Marine Sanctuary, Guindulman Church, Burial Caves (Basdio), the Eskaya, beaches, and Camp Bernido, but does not mention any bat cave in Biabas; (2) the official Bohol Provincial Planning and Development Office tourist-attractions inventory, ppdo.bohol.gov.ph tourist-attractions, accessed 2026-07-28, which lists a “Coral Seascape Tour” at Basdio, Guindulman but no cave attraction at Biabas; (3) TripAdvisor and Trip.com search results for Bohol caves (no listing for a “Biabas Bat Cave” turned up — only Hinagdanan, Cabagnow, and other unrelated Bohol caves); (4) general and Cebuano/Filipino-language web searches (“lungib Biabas Guindulman kabog paniki Bohol”) for blogs, Facebook posts, or Google Maps listings — no independent page, review, or photo set for this specific cave was found. The cave appears to exist only in the BPTO provincial inventory entry this profile is built from, with no publicly indexed secondary source yet describing its physical characteristics, fee, or access details. A future pass could try direct outreach to the Guindulman Municipal Tourism Office or CENRO-Bohol for site records, or a targeted visit/on-the-ground photo survey, since desk research has now been exhausted across the source types listed here and in the prior pass.
