Located an hour northeast of Los Angeles by way of Interstates 10 and 15, the San Manuel Amphitheater is the largest outdoor amphitheater in the United States, holding some 65,000 attendees in its reserved seats and grassy general-admission areas. Built in 1982, the venue was partially funded by Apple co-founder Steve Wozniak and was built to host giant festivals that he put on in 1982 and 1983. Acts such as Van Halen have given way to bands like Mumford & Sons and big hip-hop festivals, but the place still packs 'em in. It's a pretty spot; the venue's location in San Manuel Regional Park offers plenty of green space for preshow tailgating, Frisbee throwing and general revelry. There are even campsites available for fans who want to make a night of it. 2575 Glen Helen Pkwy., San Bernardino. (909) 880-6500, livenation.com/venues/14768/san-manuel-amphitheater. —Katie Bain
