From the dirt pullout with a BLM sign for Sheets Gulch Trailhead, follow the obvious footpath over a hill and into a sandy wash. The scenery is rather unremarkable at first, but after about a mile, the walls start to close in, and the canyon enters a slot through light-red sandstone. The walls undulate in tandem on either side, sometimes only a few feet apart. In this tight corridor are several obstacles, including wedged boulders and possibly pools of water, requiring scrambling and perhaps wading to proceed.

The narrows eventually open up into a wider section, with huge domes of yellowish sandstone appearing overhead. The canyon continues in this fashion, alternating between narrows and broader sections, with unique character to the rocks in each stretch. After the second section of narrows, a tall natural arch can be seen in the yellow cliffs above.

The third and final narrows are the tightest of them all and have the most significant obstacles. Boulder jumbles, log jams, and cold pools should be expected. Eventually, the canyon runs into a 30-foot-tall pouroff over a large pool. This can be surmounted by backtracking to a cairned bypass route, but most hikers turn around here and retrace their steps to the start.

The canyon supposedly gets less interesting above the tall pouroff, but can be followed onward all the way to Tantalus Flats on South Draw Road. The extended trip could be an option for overnight backpackers (backcountry permit required) or for those who set a car shuttle at the other end.
