Olango Island Wildlife Sanctuary

Overview

The Olango Island Wildlife Sanctuary (OIWS) is a protected wetland on the southwest side of Olango Island, Cebu, spanning roughly 1,020 hectares of tidal flat. Mangrove forest, mudflat, and seagrass bed together form the spawning, nursery, feeding, and shelter ground for hundreds of fish species, crustaceans, and invertebrates — and that concentration of marine life is what draws the birds in such numbers.

It’s the Philippines’ first wetland of international importance for waterfowl: President Corazon Aquino declared it protected under Proclamation No. 903 on 14 May 1992, and it joined the Ramsar List of Wetlands of International Importance on 1 July 1994. The site is now counted among the world’s seven major flyways for migrating birds.

More than 10,000 migratory birds pass through Olango each year, out of 97 recorded species — 48 migratory, 42 resident, 7 unclassified. Of those, 54 are waterbirds: 32 waders, 13 waterfowl, 9 seabirds. Chinese Egrets, Asiatic Dowitchers, Eastern Curlews, Plovers, Sandpipers, Black-tailed Godwit, and Red Knot are among the species most frequently sighted.

Location

Southwest side of Olango Island, Lapu-Lapu City, Cebu. Olango is five kilometres east of Mactan Island. The sanctuary is administratively in Cebu province, not Bohol, but is included as a recognised excursion destination from northern Bohol (Getafe, Talibon, Tubigon).

The coordinates listed above mark the sanctuary’s general location rather than a precise entrance pin — confirm the exact visitor centre entrance with your boat operator or the DENR staff on arrival.

Getting There

From Mactan Island, bancas reach Olango in 15–20 minutes. The sanctuary has two entry points: the DENR-operated visitor centre, and access via the community-based Olango Birds and Seascape Tour organised by the Suba, Olango Ecotourism Cooperative.

From northern Bohol, the route goes via Cebu or Mactan ferry, then onward to Olango by banca. There is no direct Bohol–Olango ferry. As of 2026, OceanJet runs Cebu City–Getafe (northern Bohol) in about 1 hour 15 minutes (roughly ₱450–800), and Cebu City–Tagbilaran in about 2 hours (roughly ₱800–1,200); from Cebu City or Mactan, add a road transfer plus the 15–20 minute banca crossing to Olango. Visitor centre hours are 8:00 AM–5:00 PM; a current phone contact for the visitor centre isn’t reliably published, so confirm arrangements through the DENR Region 7 office or a Suba, Olango Ecotourism Cooperative tour operator before your trip.

Practical Info

• Protected area: Proclaimed 14 May 1992 (Proclamation No. 903); Ramsar Site since 1 July 1994

• Bird species: 97 total (48 migratory, 42 resident, 7 unclassified)
• Peak visit window: July–November (southward migration) — highest bird concentrations
• Return migration: February–May (birds return to breeding grounds in Siberia, northern China, and Japan)
• Best tide for birding: 1.2–1.4 m high tide — birds congregate on the exposed flats in the open; outside this window, birds are sheltered in mangroves
• Management: DENR through a Protected Area Management Board (national, local government, private sector)
• Community access: Olango Birds and Seascape Tour / Suba, Olango Ecotourism Cooperative — tourism proceeds distributed as wages to workers and boat operators
• Entrance fee: ₱100 per person (visitor centre)
• Visitor centre hours: 8:00 AM–5:00 PM

What to Expect

The tidal flat is the primary habitat. At the right tide height, 1.2–1.4 m, wading birds fan out across the exposed mudflats in concentrations visible without binoculars from a distance. Community-based tour operators are the ones to guide a visit here, both for species identification and for reading the tide schedule correctly. The southern migration, July–November, brings the largest numbers — birds that have flown 3,000 to 15,000 km non-stop before landing, which is why feeding intensity on arrival runs so high.

Notes

• Best bird-watching months: July–November (southward migration)
• Check local tide table before visiting — 1.2–1.4 m is the optimal bird-watching tide
