This trail starts and ends at the bottom of the canyon when following Tim's Trail or Tower Trail to the bottom. The normal loop is done clockwise, but can be ridden in either direction. If riding the trail clockwise, it is 2 miles to the top corner, and 1 mile of downhill.

The trail is rough at this point, but should be good with extra traffic. From the start, you simply head south west toward I-84 and will begin a series of switchbacks and turns toward the top. Once you crest the steep hillside, you have a small reprieve downhill as you head west and then more switchbacks to the very top corner. Once you make the corner, you will turn back East and head down some fun switchbacks and over a drop back toward the bottom.

You can ride out Tim's trail as it will lead you back to the top parking lot.
