I have to agree with Trackrig, see the Grand Canyon first or you will be disappointed after seeing the 5 great parks in souther Utah. You can do the circle after seeing the Grand Canyon. You can easily do all of this in 4 weeks spending a few days at each park. Bryce is by far my favorite. And if you like to hike there are many good trails down into the hoodoos. Check these parks out online and go see them. You will not be disappointed. We went to the Grand Canyon after seeing the Utah parks and we were disappointed. It is deep and awesome but for scenic beauty it can't compare to the Utah NPs. Also Dead Horse SP near Moab offers a spectacular rim view of Canyonlands NP. Absolutely beautiful.
