Dawn light slides across the Bohol Sea as skiffs cut through glassy water toward a knuckle of fins and slow-moving shadows. In Oslob, the whale sharks—the ocean's placid giants—move within arm's reach, mouths open to surface plankton and the occasional hand-fed offering that has kept them lingering in these warm currents.

History
Oslob’s relationship with whale sharks grew in the 2010s when local feeding practices drew tourism that reshaped the town’s economy; Sumilon Island was later established as an early marine protected area to conserve nearby reefs.
Conservation
Operators and NGOs are working to balance tourism and protection with regulated visit times, mandatory guides, and marine park fees that fund reef management; visitors should prioritize reef-safe products and follow rules to reduce impact.
