Some 2,200 works of art are kept on 900 stunning acres, centering on a 35-acre pond. Though the main gallery is closed for renovation through late 2017, much of the grounds and its works (delightfully fractured, wild, avant-garde experiments, many of the kinetic variety, and every one of them by Bay Area artists) are still accessible. You can pay $5 and browse the collection on your own or take one of three 90-minute tours ($12, including the $5 admission), which give you an overview of the property’s highlights, including the Historic Residence and the core of the collection. Students of landscaping and architecture won’t want to miss it, nor will fans of eccentric contemporary art. Others may leave scratching their heads. But no one departs without sighing over the greenery at least once.
