From San Francisco: take Highway 101 North.
Santa Rosa is about 60 miles north of the Golden Gate Bridge (one hour by car, depending on traffic). Stay on Highway 101 through Santa Rosa to the north side of town. Take Exit 491(Guerneville Road/Steele Lane); this will be the next exit after the College Avenue exit.
At the signal after exiting Highway 101, turn left onto Steele Lane and go under the freeway overpass, being sure to get into the extreme right lane. Cross Cleveland Avenue at the next signal, and once across stay in the right lane. The street splits and Steele Lane becomes West Steele Lane which goes straight, and Guerneville Road curves to the left. Continue on West Steele Lane through the next signal at Range Avenue.
On the right side in the next block you will see The Redwood Empire Ice Arena and Snoopy's Gallery & Gift Shop set back from the street among the trees. The Museum is on the corner of West Steele Lane & Hardies Lane, just past the Ice Arena.
