Biri Larosa Protected Landscape and Seascape in Northern Samar

The Biri Larosa Protected Landscape and Seascape, situated in Northern Samar, Philippines, approximately 25 miles west of Catarman, safeguards the Balicuatro Islands. This archipelago includes Biri Island, the largest and northernmost among them, along with smaller associated islands. Perched along the northwestern coastline of Samar within the San Bernardino Strait, this protected area stretches its boundaries to encompass the coastal realms of adjacent municipalities, incorporating the first two letters of Lavezares, Rosario, and San Jose into its nomenclature.

The focal point of this destination is its seven colossal rock formations—Magasang, Magsapad, Macadlaw, Puhunan, Bel-at, Caranas, and Pinanahawan. Formed over millions of years due to underwater tectonic plate movements and the relentless impact of waves, these formations showcase the area’s geological wonders. Unique natural saltwater pools at Bel-at and Caranas offer visitors an opportunity to swim in pristine waters.

Biri Island, stretching approximately 4.0 miles northwest to southeast and 2.0 miles wide, boasts a rugged landscape, featuring a 200-foot rocky bluff on its northwestern side. The island’s shores are adorned with mangroves and gravel beaches, and it is encircled by smaller islands such as Macarite, Cagnipa, Talisay, and Magesang, sheltered by fringing reefs.

Established in 2000, the Biri Larosa Protected Landscape and Seascape spans 82,760 acres of land and sea. Renowned for its breathtaking rock formations, pristine beaches, coral reefs, seagrass beds, and rich mangrove forests, the protected area also attracts surfers to the challenging waves and currents of the San Bernardino Strait.

Encompassing 201.5 acres of coral reefs, the Biri Larosa protected area hosts a diverse marine ecosystem, supporting 23 reef fish species, including the siganid. Additionally, it comprises 1,090 acres of mangrove forests, providing habitat for various bird species and shellfish. Seagrasses cover approximately 700 acres, featuring five distinct species.

Accessing this protected area involves various transportation modes. Visitors can fly to Catarman Airport in Northern Samar and then travel by land to Lavizares seaport. From there, regular boat trips, facilitated by bangkas or pumpboats, transport travelers to Biri Island.
