From Phoenix, take I-17 North and take Highway 69 towards Prescott Valley. When you reach town, after about 1 mile, turn right on Glassford Hill Road (it'll be after the Del Taco restaurant). Travel straight about 4 blocks (the building will be readily visible as it looks like a volcano!) and turn right on Lakeshore Blvd. Turn left on Civic Circle and then almost immediately, turn right into the parking lot. The main entrance to the Library is straight ahead. Park anywhere in the lot.
