Alder Island Nature Trail caters to visitors on foot, opened in 2017, and is 0.85 miles (1.37 km) round trip.

[5] Siletz Bay NWR was established in 1991 primarily to return salt marsh to its natural state.

One segment of the refuge near Millport Slough, an arm of the lower Siletz River, consists of a 100-acre (40 ha) tidal marsh restored by the United States Fish and Wildlife Service, Ducks Unlimited, and the Confederated Tribes of Siletz.

Salt-starched skeleton trees are visible along both sides of U.S. Route 101 (which runs through the refuge) from the time when the salt marsh was diked.
