From San Francisco via the Oakland Bay Bridge
Take Interstate 80 East as if you were going to Sacramento. If you are coming from the south (for example from the SFO airport) take Highway 101 North and follow the signs to merge onto Interstate 80. Take 80 across the Benicia bridge and stay on 80 until you see the exit for Highway 12 West. Take Highway 12 west to Highway 29. Turn right at the light onto Highway 29. Go north to the first stoplight and stay in the left lane thus staying on Highway 29 North. Go north on Highway 29 through St Helena until you reach Deer Park Road. Turn right and go about 1 mile west to the Silverado Trail. You will see a flashing red light. Go straight through the intersection staying on Deer Park Road. Go 3.5 miles until you reach White Cottage Road. White Cottage is marked with a green road sign before the turn. You can only turn left onto White Cottage. Take this 1.5 miles to the winery. The entrance is on the left and you will see the sign before you reach the turn-in.
