Stebbins Cold Canyon Reserve is accessed only by pedestrian trails that begin from the California Department of Fish and Wildlife’s Putah Creek Wildlife Area (PCWA). The PCWA is 15-minute drive west of Winters, CA, or a 2-hour drive northeast of San Francisco.
From Davis, take Covell Blvd./County Hwy E6 to Winters. Proceed straight through Winters, following Hwy 128 towards Lake Berryessa. Approximately 8.5 miles west of Winters, Hwy 128 crosses Putah Creek.
The designated parking area is on the right-hand side of the road, just across the bridge across Putah Creek. UC Davis specifically advises against parking along the roadway, as there is no designated pedestrian crossing and no dedicated traffic controls along this stretch of Highway 128.
Do not leave valuables in cars.
