Donsol Coastal & Island Group Guide: The Marine Island System of Southern Bicol

The Donsol Coastal & Island Group represents the southern coastal and offshore island system of the Bicol Peninsula Cluster. Centered on the waters of Donsol Bay, Ticao Pass, and the northern approaches to the San Bernardino Strait, the cluster combines small offshore islands, productive marine ecosystems, coastal villages, mangrove environments, and some of the most important wildlife waters in the Philippines.

Unlike the limestone islands of Caramoan, the Donsol cluster is defined by marine biodiversity and coastal island environments. The region serves as a transition zone between mainland Bicol and the island systems of Ticao, Burias, and Masbate.

As a key component of the Bicol Peninsula Cluster, the Donsol Coastal & Island Group complements the Caramoan Islands Cluster by showcasing the marine ecosystems, offshore islands, and coastal environments of southern Bicol. The region serves as a natural bridge between the mainland peninsula and the island systems of Ticao, Burias, and Masbate.

The cluster encompasses a collection of coastal environments and offshore islands extending across the waters between northern Sorsogon and the Southeastern Luzon Island Cluster.
