Sumilon Island

Sumilon Island is a 24-hectare coral island off the southeastern tip of Cebu in Bancogon, Oslob, about 15-20 minutes by pump boat from mainland Cebu. Established in 1974 as the Philippines' first marine protected area with guidance from Silliman University, it is notable for its shifting white sandbar, clear turquoise waters, marine sanctuary, historic lighthouse, natural lagoon and mangroves, operating partly as a protected seascape and partly as an island resort.

Visitors reach the island by pump boat from Bancogon Port and find a small, low-lying coral island with a prominent white sandbar that shifts with seasons and tides, clear waters for swimming and snorkeling, a designated marine sanctuary with coral reef, a forested interior with walking trails, a natural inland lagoon, a historic lighthouse and watchtower ruins, and resort-managed areas with cottages and dining for day-tour guests. The environment is quiet and natural, with sandy beaches, rocky coves and forested paths to explore.

Sumilon Island was established in 1974 as the first marine protected area in the Philippines under the guidance of Silliman University Marine Laboratory, creating a no-fishing marine sanctuary that became a national model for reef conservation and community-based coastal resource management. The island also retains a historic lighthouse and remains of a Spanish-era baluarte watchtower used for coastal defense.

The island is recognized nationally as a pioneering site for marine conservation and sustainable fishing practices, demonstrating the value of protected seascapes to local fishing communities and influencing the establishment of marine sanctuaries across the Philippines.
