When perched atop a dune at White Sands National Monument, your first impression is that you're standing in the world's biggest sandbox. Your second impressionif you're like meis that you must run, roll, and dive among the dunes until you fall down, exhausted and sand-encrusted.
White gypsum sand, constantly rearranged by strong westerly winds, covers nearly 275 square miles. The best hike is the 4.6-mile trail to Alkali Flat. Camp anywhere off the trail, but leave some bread crumbs: It's frighteningly easy to get lost. SLEEP: Sierra Grande Lodge and Spa is in
