Respect Closed Zones:

National Wildlife Refuges were created for wildlife. Areas throughout the refuge are designated as closed or restricted-use areas to protect wildlife or for public safety. Please read and adhere to the regulations identified by signs.

  • OPEN Areas: Areas open to public use will be posted as such. Road entrances to public use areas have a large brown refuge sign, open gate, and posted hours. Areas open to the public include designated Auto Tour Routes, Nature Trails, and Parking Lots. 

  • CLOSED Areas:  Areas closed to the public include all property that is not explicitly posted as an area open to the public. Closed area boundaries are posted along accessible areas with signs that may list the following: “UNAUTHORIZED ENTRY PROHIBITED”; “AREA BEYOND THIS SIGN CLOSED All public entry prohibited.” Visitors must stay out of posted closed areas. Visitors that enter posted closed areas are trespassing and are subject to law enforcement action including citations.



Hunting is allowed in designated areas of Sacramento NWR, Delevan NWR, Colusa NWR, Sutter NWR, and Sacramento River NWR with appropriate licenses and permits. Visit the Sacramento NWR Complex hunting page and the Sacramento River NWR hunting page for more information.



Dogs are allowed where visitors are allowed. Dogs must be on-leash (no more than 6 ft long) while on trails or parking lots, except for authorized hunting activities under the immediate control of a licensed hunter. Owners/handlers are responsible for disposal of dog droppings on refuge public use concentration areas such as trails and parking lots. National Wildlife Refuges provide habitat for native wildlife. Pets (including waterfowl) are not allowed to be released on the refuge.


The on-refuge speed limit is 15 mph.



The Complex is committed to providing equal opportunities for all of our visitors. Refuge-specific brochures are available in Braille and audio versions. A CD is available in the Visitor Center describing the Auto Tour of the Sacramento NWR. All tour routes, platforms, and public buildings have access for people with disabilities. The north loop of the Wetland Walk Trail is wheelchair accessible. The restrooms at Sacramento and Colusa NWRs and the Llano Seco Unit are accessible.
