Palm Springs Air Museum
745 N. Gene Autry Trail, Sunmor
If you have a plane-obsessed child, or any interest in military history, this is a pretty great way to pass a couple of hours. Occupying several hangars—and staffed by some pretty wonderful and knowledgeable military veterans—you can explore any number of planes (you can climb into the cockpits of several). There are also some great exhibitions lining the walls.
