Gifted to the city by the late, great Warren Hellman and held in a corner of Golden Gate Park that now bears his name, the free three-day music fest returns every October with an eye-crossing number of acts. Plot your schedule to catch legends like Lucinda Williams, Cheap Trick, Randy Newman and Emmylou Harris alongside more Millennial-friendly fare including First Aid Kit, Conor Oberst and Brandi Carlile. Food vendors will be on-hand to keep you nourished, but note that the event is strictly BYOB.
