Sacramento National Wildlife Refuge (Willows, CA): The entrance road, visitor center parking lot, and north-side walking trails will be under construction starting June 16 through mid-September. What does this mean?
- Access to the Auto Tour route may be closed for a short duration during this window (specific dates forthcoming).
- The north-side walking trails will not be available to visitors (south-side trails will not be under construction and will be accessible depending on parking lot availability).
- There may be times where getting to the bathrooms outside the visitor center won't be possible, so please use the vault toilet out on the auto tour instead during these times.
Thank you for driving slowly, following all flaggers directing traffic, and honoring any closures while this important work is completed this summer.
Additional time-sensitive information will be shared here or on our social media pages as needed.

What to Expect
You can expect to see something different every time you visit the Complex, depending on the SEASON:
FALL means the return of migratory waterfowl in September, whose numbers build into the WINTER until they peak in late November and early December. Raptors follow and eagles, hawks and falcons are easy to see. In late December as new areas across the valley fill with rainwater, ducks will start to disperse while goose numbers peak, but by late January wildlife viewing of the massive flocks becomes less reliable as they move across the valley, though it is still very impressive! The arrival of SPRING means that our winter guests start to head north again to breed, and bird numbers decline and wetlands are drawn down to germinate food plants on the warming soil. Shorebirds stop by on their way north to take advantage of the shallow drawdowns. SUMMER brings irrigations to produce seed-bearing plants and support resident wildlife like mallards, Canada geese, herons, egrets, grebes, snakes, turtles, otters, rabbits, deer and many more! The refuges remain dotted with a few permanent wetlands for our year-round residents until the following FALL when flood-ups begin again to prepare for the returning migrants.
Hours and Directions
Our Maps, Directions & Brochures page has downloadable maps, brochures, and written out directions for the refuges, spring trails and hunter check stations.
Hunting frequently-asked-questions like hours and seasons of operation can be found on our main Hunting page, and provides additional links to special hunts, youth and junior hunts, and hunting on the Sacramento River NWR.

Applying for Special Use Permits
Special Use Permits enable the public to engage in legitimate wildlife-related activities that would otherwise be prohibited by law. Service permit programs ensure that such activities are carried out in a manner that safeguards wildlife. Additionally, some permits promote conservation efforts by authorizing scientific research, generating data, or allowing wildlife management and rehabilitation activities to be considered.
Visit the National Wildlife Refuge System website for Special Use Permit Applications
Examples of activities that require a Special Use Permit, if deemed compatible with the USFWS Mission and the Refuge Purpose and approved by the refuge manager, could include:
- Commercial filming (audio, video, photographic products of monetary value)
- Commercial guided tours/trips for hunting, fishing, bird watching, photography or other outdoor activities
- Research and monitoring activities by students, universities, or other non-FWS organizations
- Large wildlife-oriented organized events (birding, wildlife watching, festivals).
