Nantucket, Massachusetts Leave the car behind and do Nantucket by bike. The pedaling is easy, and the island's small scale makes you feel you're really getting somewhere, especially when you hit the bluffs and get that Atlantic panorama. Picnic benches and water fountains are conveniently provided at strategic points along all the paths, which you'll appreciate if you're towing really young ones in a bike trailer.
Monument Valley Navajo Tribal Park, Utah - When most of us think of the American West, this is what clicks into our mental View-Masters: a vast, flat sagebrush plain with huge sandstone spires thrusting to the sky like the fingers of ancient Mother Earth clutching for the heavens. Ever since movie director John Ford first started shooting westerns here in the 1930s, this landscape has felt familiar to millions who have never set foot here.
American Museum of Natural History - How many children have fallen in love with dinosaurs in the echoing galleries of this world-class New York City museum? When you enter the magnificent rotunda at the top of the Central Park West steps, a rearing skeleton of a mommy dinosaur protecting her baby from a small, fierce predator clues you in that the dazzling interactive 4th-floor dinosaur halls are the perennial star attraction. It's one of America's great museums, and engrossing for children.
