"Tom's Thumb Trail is a favorite among the 30,500-acre McDowell Sonoran Preserve. The four-mile out-and-back trail is short but steep and full of switchbacks. Rest assured that the views of the McDowell Mountains and Phoenix are well worth the effort. As with many other hiking trails in the area, the Tom's Thumb Trail does not have drinking water and is not shaded, so plan your trek accordingly." - Travel + Leisure Editors
