Halfway through Shenandoah National Park, US-211 runs west down to Luray Caverns (540/743-6551, daily, $27 adults, $14 children), the largest and most impressive in the eastern United States—there are 64 acres of caverns to explore. It also boasts the “World’s Only Stalacpipe Organ,” where rubber mallets make music by banging on the stone stalactites. There’s also a large antique car museum and the Luray Valley Museum (included in caverns admission), and a garden maze ($9 adults, $7 children).

Near the caverns, along US-211 a half mile west of town, the Luray Zoo (540/743-4113, daily, $12 adults) is an animal rescue center and zoo that’s home to a few hundred animals and one of Virginia’s largest collections of scaly creatures. Cobras, alligators, and lemurs coexist with uncommon birds, big cats, and cheerful, playful monkeys. For younger children, there’s also a petting zoo.
