If a short, leisurely stroll through a high desert slot canyon appeals to you, then you will enjoy Upper Antelope Canyon.
This was a very lazy hike through a picture perfect slot canyon that eventually feeds Lake Powell. The main attraction here are the uniquely shaped sandstone walls of the canyon. This is a good way to kill an hour or two if you're in the area.
If you're there for pictures, try reaching the canyon in the middle of the day for the best light. In winter time, late in the day, the light in the canyon is too low for good pictures.
If you liked this, you might want to try Lower Antelope Canyon as well.
