$12 for a Day at the Annual Spring Garden Tour on May 5 ($25 Value)

The Annual Spring Garden Tour grants visitors access to eight private gardens sprinkled across Ventura. After picking up their maps at the Villa Tasca Gardens, guests set out on the self-guided tour, driving themselves to each destination. Guests can seek inspiration for their own plots or get-rich-quick beanstalk schemes at a Mediterranean-style villa garden with views of both the hillsides and the ocean as well as admire succulents sprouting from a beachside specimen garden. At the Italianate villa on Kalorama, they can pause to partake in raffles, sip refreshments, and peruse plants and boutique wares from local artisans. The gardens will be open from 9:30 a.m. to 4:00 p.m., with final admittance no later than 3:45 p.m. Guests should allot four hours to meander through all eight gardens.
