Pamilacan is a small coral island in the Bohol Sea, home to about 250 families and surrounded by some of the richest waters in the Visayas. The island's name comes from "pilak," a large hooked implement the islanders once used to catch manta rays and whale sharks. Those days are over — marine mammals are now fully protected by Philippine law — but the jaws and bones of past catches still decorate some village homes.
The waters around Pamilacan are a breeding ground for dolphins, whale sharks, and Bryde's whales. Dolphin-watching trips leave from the island early in the morning, and sightings are common. The island itself has a 200-year-old Spanish watchtower on its northeast side, a small chapel with an old Santa Cruz at the altar, and white sand beaches rimming a rocky interior where you can spot fossilised seashells in the limestone.
The marine sanctuary off the coast offers good snorkelling over healthy coral, and the slow pace of village life makes this a worthwhile day trip from Panglao.
