The 1.5-mile hike through the Boyce Thompson Arboretum is gorgeous and deeply informative any time of the year. But only in fall, as you walk down through the steep-walled Queen Creek Canyon, do you pass through hundreds of different tree species from ecosystems around the world changing colors together. It's a palette seen in few places on Earth. And surprisingly, most visitors come to the Arboretum in the spring, leaving the paths fairly quiet during this spectacular show.

One caveat this fall, though. As with much of Arizona, the drought has taken its toll on the plant life, so this autumn likely will be a replay of last year, when severe heat and dry conditions muted the colors.

As for the details: Admission is $6 for adults and $3 for children 5 to 12. Children under 5 are free. The Arboretum is open every day of the year except Christmas from 8 a.m. to 5 p.m., and is just about a half-hour east of Apache Junction on Highway 60.
