The Ute Trail to Ute Rock is Aspen's version of a short and steep butt-kick workout. If staying in Aspen, the trailhead is only a quick trip from downtown.
This shady trail of switchbacks ascends steadily (over a thousand feet in under a mile) to a rock outcropping at 9,185 feet. Yes, you can expect your heart to be pounding and to be huffing and puffing as you climb Ute Trail. But the view of Aspen that rewards you is spectacular.
The trail is pretty rocky, so hiking shoes or trail running shoes are recommended. You can still do it in regular sneakers, but hiking or trail shoes give you a little extra protection. Go early as this trail is very popular with locals and tourists.
