San Diego NWR has opened a new one-acre gravel-surfaced parking lot, located off State Route 94 at Millar Ranch Road, just east of the old steel bridge. 

The parking lot accommodates about 40 vehicles, including five pull-through spaces for equestrian trailers and school buses, and two handicapped accessible spaces. The new parking area will increase visitor access to the refuge’s Interpretive Loop trail, which connects to the county’s Sweetwater River Regional Trail, and support the current and future interpretive, environmental education, and habitat restoration programs. 

Parking lot hours will be 6:30 am to 7:00 pm during spring through fall; winter hours will be 6:30 am to 5:00 pm. Visitors can expect to also see an information kiosk with species and habitat information and a refuge trail map. Leashed dogs are welcome; don’t let your pet roam as that can harm them, other visitors, and wildlife. Visitors should follow Leave No Trace guidance - leave only your foot/tire/hoof tracks on approved trails - don’t leave trash, pet waste, artwork. And take home only photos and memories - don’t move or take rocks, flowers, plants, animals – please leave nature for others to enjoy!

Funding for this project, which also included widening State Route 94 to add a westbound left turn lane onto Millar Ranch Road and acceleration/deceleration lanes, was funded by the U.S. Department of Transportation’s Federal Land Access Program, the U.S. Fish and Wildlife Service’s National Wildlife Refuge Transportation Program, and the California Department of Transportation.
