On any given weekend at Cesar Chavez Park (11 Spinnaker Way, Berkeley), you will likely find skilled kite fliers practicing their craft. But this weekend, expect to see far more and far greater kite-related artistry at the Berkeley Kite Festival. The festival, which started in 1986, has grown into a giant kite extravaganza, featuring teams of kite fliers, a kids zone with bouncy houses and a petting zoo, and food and arts and crafts vendors. The Berkeley Kite Wranglers will also be on hand to demonstrate their Octopile, a formation of 16 Octopi kites that are each 100 feet long and 18 feet across. On the main exhibition field, teams will perform choreographed kite flying routines set to music. For attendees who are inspired to try their hand at kite-flying, Highline Kites will have kites for sale, and there will be kite-making workshops on both Saturday and Sunday from 11 a.m.-3 p.m. In addition to the parking at the marina, there will be free valet bike parking and offsite parking at Golden Gate Fields with buses running back and forth.
