Facility Rules and Policies
All areas of the Colusa NWR are closed to public entry unless otherwise explicitly posted as an auto tour route, nature trail, hunting area, or parking area. Some areas are closed seasonally and are posted as such.
The following rules apply to the Sacramento NWR Complex except where otherwise posted:
Visitors to National Wildlife Refuges must comply with all applicable local, State, Federal regulations and signs.
Fees and Permits:
The Sacramento NWR collects a $6 day use fee for the Auto Tour Route (annual passes are $12). Holders of a Federal Duck Stamp and various Interagency Passes get in for free. There are no fees for use of the trails or Auto Tour at the other refuges (Colusa NWR, Sutter NWR, Sacramento River NWR, Llano Seco Unit). Visit our Passes and Permits page for more fee information.
Specific State/Federal permits/licenses are required for hunting (Sacramento NWR, Delevan NWR, Colusa NWR, Sutter NWR, Sacramento River NWR) and fishing (allowed on Sacramento River NWR only). Visit our Hunt Area Permits page for more information. Hunters must comply with State of California license requirements and regulations. See State of California Department of Fish and Wildlife website for more information: https://www.wildlife.ca.gov/
A Special Use Permit (SUP) is required to enter closed areas or conduct activities that are otherwise prohibited (ie research projects, commercial activities, large organized events). For more information, contact the Complex Headquarters to speak with the refuge manager of the area where the proposed activity will occur: (530)934-2801. Visit our Passes and Permits page for more fee and permits information.
While on the Auto Tour Routes (Sacramento NWR and Colusa NWR), visitors are required to stay in their vehicles. The Sacramento NWR Auto Tour has 3 park-and-stretch areas to allow visitors to get out of their vehicles. This is a citable offense with fines up to $275.
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. Areas open to the public are listed on the refuge public use maps – follow the “MAPS” tab on the right side of this web page. Public use areas are DAY USE ONLY.
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.
