Flagstaff sits at 7,000 feet in Arizona's high country, a former Route 66 railroad town surrounded by the largest contiguous ponderosa pine forest in the US and topped by the San Francisco Peaks, which keep it snowy in winter while the desert below bakes. It makes an ideal cooler-climate base for the Grand Canyon's South Rim, Sedona's red rocks, and the Lowell Observatory, where Pluto was discovered — with a walkable historic downtown of brewpubs and Route 66 nostalgia to come back to each evening.
