As challenging as you want it to be. Long exposure photographer's dream. Fantastic views. No dogs allowed. Standard hike: 1.5 miles out-and-back. Elevation Gain: 625 feet.
Drive up Big Cottonwood Canyon for around 2.8 miles, parking will be along the road and there will be a large rock waterfall on the right hand side of the road. The trailhead is just a short distance from that rock fall (40.623824, -111.743208)
Stairs Gulch is an easy, short hike, unless you're looking for more. After reaching what is deemed the trail end, continue up the gulch all the way up until we reached the snow patch that remains. If you have climbing experience or are certainly capable of handling tough hikes, it will probably be easier for you. However, if you do not have such experience, I recommend not heading too far up the remainder of the gulch.
Best for the warmer months, as the gulch becomes a high avalanche risk area in the winter.
