This U.S. Registered National Natural Landmark is the Shenandoah Valley's most interesting and entertaining cave. In addition to monumental columns in rooms more than 140 feet high, you'll see beautiful cascades of natural colors on the interior walls. The works of man and nature are combined into an unusual organ that produces music when rubber-tipped plungers tap the stalactites. There are no guided tours; instead, audio tours will lead you through a system of brick-and-concrete walkways. It's about 55°F (13°C) down here all the time, so bring a jacket or sweater. You get more for your money here, for admission to the caverns includes the Car and Carriage Caravan Museum, a collection of antique carriages, coaches, and cars -- including actor Rudolph Valentino's 1925 Rolls-Royce. The complex also contains a snack bar, gift shop, and fudge kitchen. Separate admission is charged to get thoroughly confused in the outdoor Garden Maze.

Across U.S. 211 stands the Luray Singing Tower, a stone carillon with 47 bells. It was given to the town of Luray in 1937 as a memorial to one of its residents. Free concerts are given spring through autumn (pick up a schedule at the Luray visitor center or at the caverns).
