Calf Creek is a perennial stream located in the Grand Staircase-Escalante National Monument. There are two waterfalls which you can visit, the upper falls and the lower falls. The lower falls is more accessible, a bigger drop, and much more popular.
The 6-mile out-and-back hike to the lower falls is relatively flat, and the trailhead is located just off of Utah Scenic Byway 12, the highway between Escalante and Boulder. There is a sign for Bureau of Land Management (BLM) Calf Creek Recreation Area.
Although the trail is flat, it is somewhat of a slug as much of it is in the sand.
