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.

Welcome to Steve Thompson North Central Valley Wildlife Management Area (including the Llano Seco Unit)!
This WMA is primarily composed of privately-owned properties under conservation easement conservation easement
A conservation easement is a voluntary legal agreement between a landowner and a government agency or qualified conservation organization that restricts the type and amount of development that may take place on a property in the future. Conservation easements aim to protect habitat for birds, fish and other wildlife by limiting residential, industrial or commercial development. Contracts may prohibit alteration of the natural topography, conversion of native grassland to cropland, drainage of wetland and establishment of game farms. Easement land remains in private ownership.
