Biri Island Rock Formations

Biri Island Rock Formations are a group of seven distinctive coastal rock formations on Biri Island in the municipality of Biri, Northern Samar, Philippines. Located along the northern coast facing the Philippine Sea and San Bernardino Strait, the formations were shaped by tectonic movement, wave erosion and uplift over millions of years. Designated within the Biri Larosa Protected Landscape and Seascape, they are noted for dramatic cliffs, sculpted limestone, tidal pools and panoramic ocean views.

Visitors can expect dramatic coastal scenery with large sculpted limestone and sandstone formations along the shoreline, natural tidal pools, cliffs and wave-cut platforms. The site consists of seven named formations including Magasang, Magsapad, Macadlaw, Puhunan, Bel-at, Caranas and Pinanahawan spread along the north and west coasts. Access involves a boat transfer to Biri Island and guided walks over rocky, uneven terrain. Activities center on sightseeing, photography and exploring pools and viewpoints at low tide.
