I agree about Zion and we much prefer Bryce over it. And Sedona and Jerome. And many interesting ruins and can combine a nice one with Sunset Crater as has been said. Moab for Arches and Canyonlands (Island In The Sky - north section)only. We LOVE Moab and going back for 6th or 7th time next year. Agree with 2 gypsies on things to skip. We are not into the commercial type things; more with the natural beauty.
Would send you to Grand Falls but hard to find (on the reservation east of Flag - falls are higher overall and wider than Niagara Falls when there is moisture...and chocolate in color so also known as the Chocolate Falls.)
Enjoy the area.
