Visit the Refuge

Ridgefield National Wildlife Refuge

Ridgefield NWR has over 5,000 acres of marshes, grasslands, and woodlands. Preservation of the natural Columbia River floodplain is the management objective of the Carty (2-mile self guided hiking trail) Roth and Ridgeport Dairy units. The River ‘S’ (4.2 mile auto tour route and 1.2 mile seasonal hiking trail) and Bachelor Island units are managed to maximize habitat for waterfowl and other wetland wildlife.

The refuge was established (along with 3 other refuges in the Willamette Valley of Oregon) in 1965, in response to a need to establish vital habitat for wintering waterfowl with an emphasis on the Dusky Canada Goose whose nesting areas in Alaska were severely impacted by the violent earthquake of 1964.

Stately Sandhill Cranes, shorebirds, and a great variety of songbirds stop at the refuge during spring and fall migrations. Some bird species such as Mallards, Great Blue Herons, and Red-Tailed Hawks are year-round residents that nest on the Refuge. Black-tailed deer, and the threatened White-tailed deer are the largest mammals on the refuge. Coyote, raccoon, skunk, beaver, river otter, and brush rabbits can also be seen on the Refuge.

Ridgefield National Wildlife Refuge Complex

The Ridgefield National Wildlife Refuge Complex is part of the National Wildlife Refuge System managed by the U.S. Fish and Wildlife Service. There are more than 540 refuges nationwide totaling over 94 million acres of land managed specifically for the conservation of fish and wildlife and their habitats. Refuges serve to protect America’s natural and cultural heritage for all people and for future generations.

The Ridgefield National Wildlife Refuge Complex is headquartered in Ridgefield, Washington, and oversees the management of four refuges in the southwestern part of the state including: Ridgefield NWR and three refuges in the Columbia River Gorge – Franz Lake, Pierce, and Steigerwald Lake NWR. Visit the US Fish and Wildlife Service website at to learn more about these five refuges including recreational and volunteer opportunities and environmental education programs.

Entrance Fees & Passes

An important feature of Ridgefield’s recreation and entrance fee program allows 80% of the funds collected to remain at the Refuge to be used for recreation related expenses including brochures, signs, facilities enhancement, trail/road maintenance, restoration associated with wildlife-dependent recreation, and public safety.

Periodically, the refuge may be closed for scheduled maintenance or construction projects, or because weather conditions have caused refuge trails or the auto tour route to be unsafe for visitors.

Day Use Fee
There is a daily fee of $3.00 per passenger vehicle or motorcycle to enter the Carty and River “S” units. Please note that seasonal hiking restrictions apply on the River “S” unit beyond the entrance to the Refuge.

Refuge Passes
A Ridgefield NWR specific pass, valid for one year from the date of issue, may be purchased for $15.00 at the Refuge office at 28908 NW Main Ave in Ridgefield. You can also purchase a variety of other passes that grant you access to federal lands at the Refuge office. For a complete listing of federal passes available, visit the Ridgefield NWR website.
