Zion - Bryce Canyon - Arches, but the weather refused to cooperate. We had a great time visiting Zion but had to leave early due to rain and then cold weather forced us to drop plans to visit Moab.
We ended up spending some time in Green River, UT at a campground that was right behind the hotel where I spent several days waiting out the rain on my 2005 motorcycle trips! We will go back and hit some of those great hot spots.
Oh, never been there? Be sure to try US 89 for a scenic drive.
