Mystical Slot Canyon is not far from Kanab, UT is also known as Red Canyon or Peek-A-Boo Canyon. The fantastic red sandstone walls with undulating striations provide unlimited photography
The description of this location within Tonto National Forest says it is used by kayakers. My recommendation is to update the description and mention it is used by photographers too.
Diana's Throne Canyon, also known as the Huntress Slot, is a beautiful location near Hwy 89 between Mt Carmel Jct and Kanab UT. Zion National Park can be seen from the distance
