About Hundred Islands National Park

Hundred Islands National Park is a protected archipelago in Lingayen Gulf off the coast of Alaminos in Pangasinan, Philippines, composed of 124 islands and islets. The group is a nationally recognised natural and recreational area known for low-lying limestone and coral islands surrounded by clear water.

Many islands are small and undeveloped while a handful have visitor facilities, sandy beaches, reefs and simple shelters; Quezon Island is the best-known developed island and receives most day visitors. Typical visitor activities include island-hopping by motorboat, swimming, snorkeling and short hikes to viewpoints on the larger islets.

The islands are the product of coastal and marine processes acting on limestone and coral over long periods and are managed as a national park and marine protected area. Management focuses on balancing tourism use with conservation of marine habitats and shorelines.

The archipelago lies off the coast of Alaminos city in northwestern Luzon, Philippines, within Lingayen Gulf. Boats leave from the Alaminos/Lucap wharf to reach the nearest islands within minutes and the largest islands in around 15 to 30 minutes by small boat.

  • Number of islands: The park comprises 124 islands and islets scattered across Lingayen Gulf off the coast of Alaminos, Pangasinan.
  • Tours and access: Most visits are organized as island-hopping boat tours that depart from Alaminos and typically last a half day to a full day depending on the itinerary.
