Arches National Park in Moab UT

4-hour hike along a pretty primitive trail (scampering up and down rock fins and spines on my hands, knees, butt, and stomach). Many of the photos are taken from quite high up atop rock formations along trails marked only by rock cairns, but the scale doesn't seem to show it. OTHER PARTS OF THE PARK are more striking from the road or scenic overlooks, but the hiking isn't as good as this area.
