A single row can hide a real spread — open a month to see it region by region.

The Desert

Phoenix A city built around the sun — beloved for most of the year, endured for the rest.
Tucson A desert valley ringed by mountains, where summer is split in half by the storms everyone waits for.

Red Rock Country

Sedona Red rock country sits higher than people expect: real winter chill, blazing dry early summer, and shoulder seasons worth planning a year around.

High Country

Flagstaff A ponderosa pine town at real altitude — deep snowy winters, cool bright summers, and a night sky protected by local law.
Grand Canyon The rim sits high in ponderosa country with a genuine mountain winter, while the canyon floor below runs a summer entirely of its own.
