The Grand Canyon astonishes even the most seasoned travelers, but a visit here offers far more than a jaw-dropping view across a 6000-foot-deep, vermilion-streaked chasm. Park staffers point out that a significant number of visitors simply drive into the park, walk up to the canyon rim, snap a few photos and speed away. Don’t be that tourist. Give yourself 48 hours, and you’ll have the opportunity to examine fascinating exhibits on the region’s impressive human and natural history, embark on a light (or strenuous) hike and feast on local elk and trout in a grand dining room perched on the canyon’s rim. So grab your camera (and at least a 16-gig memory card) and spend some time getting to know the country’s second-most-visited national park.
