Hike Humphreys Peak
Why go: This is Arizona's highest peak, so the reasons to go should be obvious - because it's there, and because the views from the top are amazing. At 12,643 feet above sea level, the peak north of Flagstaff is a great place to test, or help build, your endurance. If you don't want to walk both ways, you can ride the scenic chairlift at Arizona Snowbowl up to 11,500 feet and hike down. It operates from Memorial Day weekend to mid-October.
Best time to go: Summer.
Insider tip: Start early in the morning. Afternoon thunderstorms can make hiking unsafe.
