Fossil Butte National Monument in Wyoming offers families an incredible journey back 50 million years to when this high desert was a subtropical lake teeming with ancient life. Kids become real paleontologists as they explore one of the world's most famous fossil sites, where perfectly preserved fish, insects, and plants tell amazing stories of prehistoric Earth.

Best Season: Late spring through early fall offers the best weather for hiking fossil trails, though the heated visitor center makes winter visits comfortable for indoor fossil exploration.
