Here are a few specific sights:

  • Rio Grande Gorge (Taos): A hike into this dramatic gorge is unforgettable. You'll first see it as you come over a rise heading toward Taos. It's a colossal slice in the earth, formed during the late Cretaceous period, 130 million years ago, and the early Tertiary period, about 70 million years ago. Drive about 35 miles north of Taos to the Wild Rivers Recreation Area. From the lip of the canyon, you descend through millions of years of geologic history If you're visiting during spring and early summer and enjoy an adrenaline rush, be sure to hook up with a professional guide and raft the Taos Box, a 17-mile stretch of class IV white water.

  • Blue Hole (Santa Rosa): You'll find this odd natural wonder in Santa Rosa, "city of natural lakes." An 81-foot-deep artesian well, its waters are cool and completely clear. Often it appears like a fishbowl, full of scuba divers.

  • Capulin Volcano National Monument (Capulin; tel. 575/278-2201; Last active 60,000 years ago, the volcano is located about 27 miles east of Raton. A hike around its rim offers views into neighboring Oklahoma and Colorado, and another walk down into its lush mouth allows you to see the point from which the lava spewed.

  • Carlsbad Caverns National Park (Carlsbad; tel. 800/967-CAVE; Truly one of the world's natural wonders, these caverns swallow visitors into what feels like a journey to the center of the earth, where nocturnal creatures thrive and water drips onto your body. Stalactites and stalagmites create another universe of seemingly alien life forms. Kids won't like the fact that they can't go climbing on the formations, but they'll be too fascinated to complain much.

  • White Sands National Monument (Alamogordo; tel. 575/479-6124; Like a bizarre, lost land of white, this place is a dream for kids. They can roll around in the fine sand or sled across it, all the while discovering the mysterious creatures that inhabit this truest of deserts. Bring extra clothing, sunglasses, and lots of sunscreen.
