A collection of massive, dramatically sculpted rock formations along the coastline of Biri Island, Northern Samar, shaped by powerful Pacific waves over millennia. The formations bear local names like Bel-at, Magasang, and Puhunan, each with distinct towering shapes and textures. The raw, windswept landscape and crashing surf create a powerful and untamed natural spectacle.
