Travel Guide to Biri Island Rock Formations in Northern Samar, Philippines
Biri Island in Northern Samar, Philippines, is home to some of the most fascinating natural wonders in the country – the Biri Island Rock Formations. These six distinct rock islands, namely Magasang, Masapad, Macadlaw, Puhunan, Bel-at, and Caranas, were formed over 20 million years ago by the movement of tectonic plates and shaped by the forces of nature such as crashing waves, winds, and storms. The resulting rock formations are a sight to behold, with their unique shapes and sizes that are nothing short of awe-inspiring.
Each of the six rock formations has a distinct look, with some towering up to 50 feet high. Visitors can explore the different formations through guided tours or by renting a boat to take them from one island to another. The most popular formations are the Fantastic Four – Macadlaw, Puhunan, Bel-at, and Caranas Rock Formations – located on Biri Island’s northern side. However, all the formations are equally impressive and offer a unique experience for visitors.
Aside from being a popular tourist destination, the Biri Island Rock Formations also have significant geological importance. Geologists from the University of the Philippines have studied the formations and found that they are composed of sedimentary rocks deposited by ancient rivers and seas. The rocks also contain fossils of ancient marine life, providing valuable insights into the area’s geological history. Overall, the Biri Island Rock Formations are a must-see destination for anyone visiting the Philippines, as they offer a unique blend of natural beauty, geological significance, and cultural heritage.
