Agoo–Damortis Protected Landscape and Seascape

The Agoo–Damortis Protected Landscape and Seascape is located on the eastern side of Lingayen Gulf in southern La Union, Philippines. It was established in 2000 to protect 10648.94 ha of coastal area, including mangrove swamps, seagrass beds and stretches of fine black sand beaches. It was first gazetted as a national park in 1965 and was known as the Agoo–Damortis National Seashore Park. It covers approximately 30 km of the coastline of Lingayen Gulf shared between the municipalities of Agoo, Santo Tomas and Rosario.

Description
The Agoo–Damortis park is located in 25 coastal barangays in southern La Union from Santa Rita in Agoo to the border with the province of Pangasinan. It is fed by three rivers, namely the Agoo, Bani and Cupang Rivers. The park includes the Santo Tomas Cove (also known as Damortis Cove) in Santo Tomas formed by a sand spit and bank on the western side which extends for 4 km southwards in the sitio of Sungyot. The 200 ha cove is the location of large tracts of fishponds, as well as the Santo Tomas Anchorage and Fish Port. On the park's northern portion in Santa Rita is the 75 ha Agoo Eco-Tourism World of Fun, an eco-tourism park developed by the local government, which contains a lagoon for fishing, kayaking and other water sport activities, and bicycle lanes along the park's seawall.

The park is just 50 km south of the provincial capital of San Fernando and 230 km north of Manila.
