Willis Creek as you can see is just magnificent! It's located off Skutumpah Road (between Mt. Carmel Jct. and Cannonville) in the Grand Staircase-Escalante National Monument. It's only a couple of miles before you would run into Sheep Creek, but you can follow that to Bull Valley Gorge (another spectacular slot canyon in the Staircase) or visa versa. Combine the three and you can have a long day hike or an overnight backpack. There is a cool stream that runs through Willis Creek. That along with the high walls makes this a great summer hike.
