In back of Sonoma City Hall is the Sonoma Valley Visitors Center. Offering complimentary maps of the plaza, and information about local wineries, shops, galleries, gardens, food, and lodging, it's a useful stop for anyone coming to wine country. The building sits at the end of Sonoma Park's green, where patrons can linger, drink wine, take a walk, or rest on bench before one of the two duck ponds. There are public restrooms outside the building.
