South Slough National Estuarine Research Reserve, established in 1974, is dedicated to improving the understanding and stewardship of Pacific Northwest estuaries and coastal watersheds.
The South Slough Interpretive Center includes a variety of exhibits, an auditorium, a classroom, and a bookstore operated by the Friends of South Slough Reserve.
The South Slough National Estuarine Research Reserve protects both upland and lowland habitats. The uplands are characterized by steep slopes that support forests and stream systems that supply fresh water to the estuary. The lowlands contain freshwater wetlands and ponds, salt marshes and islands, sand and mud flats, and eelgrass beds. Habitats found within the reserve support salmon and other native fish, herons, bald eagles, migrating waterfowl, elk, river otters, beavers, oysters, and crabs.
The Interpretive Center is open Tuesday-Saturday from 10 am to 4:30 pm, and trails are open everyday from dawn to dusk.
