Arizona is too hot to sweat your way through in summer unless you’re used to it, so head to Arcosanti in spring. Designed by Italian-American architect Paolo Santeri, this commune in central Arizona minimizes its carbon footprint through shared resource use, reduction of urban sprawl, and clever design, including solar-oriented doorways and windows. Learn about the community and then hike a few of the 860 acres of wilderness, including the Agua Fria Canyon.
