Calf Creek Falls is one of the most well known and unique features in Grand Staircase-Escalante National Monument. The trail follows Calf Creek to the 126' high falls. The hike is 6 miles round trip and takes average hikers 3-4 hours. Elevation change on the trail is minimal, but the trail is sandy and walking can be strenuous, especially in hot weather. In contrast, the falls provide a delightfully cool, shady haven which makes the hike well worth the effort.For pictures and description of this trail, see http://dyeclan.com/outdooractivities/hiking/lowercalfcreekfalls.
