To the northeast, at the Wupatki National Monument, the ancestors of today's Hopi, Zuni, and other Pueblo peoples lived what we might call a green lifestyle some 850 years ago.

The centerpiece of the park is a hundred-room pueblo, where terraced compartments face south and east to catch the winter sun; sandstone walls moderate temperature extremes; flat roofs funneled rain into clay storage jars; and corn, beans, and squash were planted together to conserve water.

"Some visitors see only a harsh struggle to survive," said Ranger Mike Koltunak. "But I think the inhabitants lived pretty well. These people knew how to manage nature's gifts."

"Wupatki reminds me how little we really need to be happy," says Gordon Watkins, owner of the Inn at 410, an 1894 bungalow at 410 N. Leroux back in Flagstaff. Guests who stay in the ten themed rooms at this sumptuous B&B certainly don't do without. Breakfasts on the shady patio include hot frittatas, fresh breads, seasonal fruits, and yogurt.

To the east of town, see how another ancient community thrived in the high desert at Walnut Canyon National Monument. Here, the Sinagua people built homes in the cliffs. The scenic but strenuous Island Trail passes by 25 different rooms while descending 185 feet in elevation. Then you climb back out.

Finally, consider a 30-mile drive due west from Flagstaff to Williams, a gateway community to Grand Canyon National Park. Here you can catch a vintage train on the Grand Canyon Railway, which offers one-to three-night trips to the South Rim and back, some including additional bus tours along the rim.

"The train is an environmentally friendly and historically appealing way to visit one of the nation's great national parks," says Jonathan Tourtellot, director of the National Geographic Society's Center for Sustainable Destinations.
