Bandon Marsh National Wildlife Refuge is a protected estuarine landscape on the Oregon coast north of Bandon, across the Coquille River from Bullards Beach State Park. Part of the Oregon Coast National Wildlife Refuge Complex, it spans 889 acres in the Bandon Marsh and Ni-les'tun units and includes the largest tidal salt marsh in the Coquille River estuary. Its mudflats and marshes support marine life, migratory shorebirds, waterfowl, salmon, and pelicans, and it is especially valued by birders. The Ni-les'tun unit is also a focus of habitat restoration and protects a 4,500-year-old Native American archaeological site associated with the Coquille Indian Tribe.
