BEVERLY HILLS. This nearly two-mile strip of green runs 14 blocks along Santa Monica Boulevard, from Doheny Drive to Wilshire Boulevard and then along Wilshire to Whittier, right through the heart of Beverly Hills. The site of several annual events, the park is also notable for other reasons. Between Camden and Bedford Drives is a large cactus garden, one of the largest collections in the world. A jogging path runs the length of the park, past statues and flower gardens. At the southwest end, the 1931 Electric Fountain runs through a changing display of color effects every eight minutes.
