"Little Wild Horse is a classic slot canyon located in south-central Utah, near Goblin Valley. It is a popular hiking spot for families and youth groups. The main attraction is a long stretch of "narrows," where the canyon walls are so close you have to turn sideways to get through. The rock walls are sculpted and very beautiful.
There are two popular approaches to hiking here. Some people simply go into Little Wild Horse, hike as far as they feel comfortable and then return the way they came in. More adventurous people make a loop by hiking up Little Wild Horse and then crossing over and descending Bell Canyon. The loop hike totals about 8 miles, and is moderately strenuous." from Little Wild Horse Canyon | Utah.com
