How long: Depends how adventurous you are. Some adventure trip planners argue that Copper Canyon comprises almost 1500 miles, doable in about a week's time.
Why: Unlike the Grand Canyon, for example, there is a canyon in north-central Mexico with fabulous driving roads. The driving at Copper Canyon, which is actually more of a collection of canyons, water features, and geological formations in an arid desert setting, is otherworldly. Bring a motorcycle or a traditional automobile and prepare to spend hours on dirt paths and paved roads alike.
When: Temperatures become bearable in the wintertime, although it's never a bad time of year to visit Copper Canyon.
