The last time I visited Anza-Borregoa forbidding wilderness extending from the Salton Sea west to the Laguna Mountains and from the Mexican border north to Riverside Countya friend and I mountain-biked up to the Carrizo Badlands Overlook for views of a 100,000-acre expanse of alkali desert and small ranges, where sunsets turn the jagged little mountains flame-red. Another favorite jaunt of mine is hiking two days through Coyote Canyon, with its riparian woodlands of willow, California fan palms, mesquite, and acacia, and spring-fed Coyote Creek.

Arizona: Saguaro National Park
This two-part park to the east and west of Tucson is made for winter hiking. Head to the 66,621-acre Rincon Mountain District, in Saguaro National Park's eastern section15 miles east of the cityfor more than 120 miles of trails threading pines, at higher elevations, and saguaros, on the desert floor.
The graceful saguaro is one of the world's largest and slowest-growing cactuses, reaching up to 50 feet over the course of two centuries. Hiking among them is the quintessential desert experienceespecially at dusk, when the giants are silhouetted against purple twilight.

New Mexico: White Sands National Monument
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.

The most popular Big Bend attraction is floating the Rio Grande through some of the country's most remote canyons, in the immense Chihuahuan Desert. Santa Elena Canyon, with its 1,500-foot limestone cliffs and Class IIIIV rapids, is the most impressive and most frequently rafted, but some of the more isolated lower canyons are well worth seven- to ten-day trips.
