Vista sits in North San Diego County, a city of hills, groves, and a lively downtown. The Moonlight Amphitheatre, an outdoor stage in Brengle Terrace Park, hosts musicals under the stars each summer, and Rancho Guajome Adobe, a historic adobe ranch house from 1852, preserves the region's rancho days in a county park. Downtown Main Street keeps shops, cafes, and a farmers market, and the Antique Gas and Steam Engine Museum shows the farm machines that worked the surrounding groves. Alta Vista Botanical Gardens offers sculpture and plants on a hillside above town.
