This is the popular access to "The Wave".
From the Wire Pass TH, walk 0.5 miles downstream along the wash until you get to a sign indicating "Buckskin Gulch/Coyote Buttes". The trail to the Wave will veer of to the right out of the wash and up a steady incline. At the top of the ridge, the path turns South and levels off heading towards a butte. You will pass a trail register box indicating "Special Permit Required". Link to permit info is in the driving section.
At about mile 1.0, the trail ends after crossing a wash. Head East over a low divide on a slick rock ridge. Note that there is no Cairns. I'm told that Rangers remove any they find. About 150 ft after you cross through a small pass, head South along the East side of Coyote Butte. At about mile 2.0 you will encounter the famous Wave.
