My husband and I will be flying into Salt Lake City around 1p.m. on Sept. 17th and then fly out to Denver to visit Rocky Mountain NP on the 25th. We have gone around and around as to whether we should head to Bryce, Zion, Arches, Canyonlands, and the North Rim, or head north and visit Grand Teton and Yellowstone. We visited the South Rim last October and loved it. We live in Florida so this will be a great contrast in scenery, climate and altitude for us. We are thinking about bringing our tent so that we can affordably stay right in the parks. What do you all suggest? Should we head north or south? Would it be too uncomfortable to camp that late in September? How many parks could we do without rushing it too much? Also wondered about rafting at either place. Would really appreciate any input!
