Tour Bryce Canyon, Zion Canyon, Snow Canyon, north rim of the Grand Canyon, Brigham Young winter home, Joshua Tree Forest, etc. Our most memorable moments were seeing eagles. We had never seen a free one before but we saw at least six during our week in SW Utah.
Quick Tips: St. George seems to be one of the warmest places in Utah during the winter. There are a tremendous number of things to see near it, a really nice town and a great base from which to tour.
Best Way To Get Around: Due to the many sights being spread out, a car is a necessity.
