It’s easy to be a tree-hugger in Flagstaff, where pines are plentiful, and natural pursuits are obvious. The San Francisco Peaks are popular with hikers (Humphreys Peak is the highest point in the state, at 12,643 feet). The Arizona Snowbowl welcomes snowboarders and skiers in winter and operates as a scenic sky ride in summer. Biking and hiking shacks, casual cafes and reliable bars pepper the downtown streets, one of which is the longest remaining stretch of the original Route 66. If you have intellectual pursuits in mind, consult the Museum of Northern Arizona, which spans fine arts, natural sciences and native cultures. Or, wander around Lowell Observatory to view the telescope that discovered the “dwarf planet” Pluto in 1930.
