With a trailhead at Fairyland Point north of the visitor center, this 8-mile round-trip makes for a beautiful half-day hike (four to five hours). The tall hoodoos and bridges unfold best if you go in a clockwise direction. On the trail there's a 700ft elevation change, plus many additional ups and downs, making this a good fitness challenge.
At around mile 4 (if walking in a clockwise direction), you will run into a side trail that takes you to the base of Tower Bridge, a crumbling formation that looks like a castle, complete with drawbridge, turrets and goblins. This is the bottom point of the trail. From there, it's a rather long ascent over rolling moonlike terrain back to the rim near Sunset Point. You can take a break here, grab food at the General Store, or just carry on for the last 2.5 miles on the Rim Trail back to the start at Fairyland Point.
