Hundred Islands - Pangasinan

The Hundred Islands National Park is located in Brgy. Lucap, Alaminos City, Pangasinan, about 250 kms from Metro Manila. The islands (124 rocky islets at low tide and 123 at high tide) are scattered along Lingayen Gulf and cover an area of 18.44 square kilometres (1, 884hectares or 4,557 acres). To present, only 3 islands have been developed for tourists: Governor Island, Quezon’s Island and Children’s Islands.. Anda, northwest of Alaminos City, is known to be the "mother island" of the Hundred Islands. It was established as National Park on January 18, 1940 under Proclamation No. 667 issued by the late President Manuel L. Quezon making it the first national park, and in whose honor the biggest of the islands was named.

They are believed to be about two million years old. The islands are actually composed ancient corals that extend well inland, in an area previously comprising the seabed of an ancient sea. Lowering sea levels have exposed them to the surface and the peculiar mushroom-like shapes of some of the islands have been caused by the eroding action of the ocean waves.
