The Balingasay River has been recognized as the cleanest river in the Ilocos Region, having won the Gawad Pangulo sa Kapaligiran Award for inland bodies of water twice. The river is also home to 15 hectares of mangroves that have since been home to a teeming biodiversity. With the river’s fresh water meeting the seawater of the West Philippine Sea, the Balingasay River has become an ideal site for unique marine creatures.
