We were hoping to do a 4 week loop after labor day weekend...Zion, North Rim, Bryce, Escalante Petrified Forest, Burr Trail then up Notom Bullfrog to Capitol Reef, Natural Bridges, Canyonlands Needles, Island in the Sky, Deadhorse Point and Arches, with some smaller stops like Calf Creek, Goblin, etc. but now I am getting worried about campground (tenting) availability without reservations. am eligible for my senior pass in July. would August be too late to book some reservations, and can you get in the first come first served campgrounds if you get there before 10 or 11? am I the only one that thinks it's hard to preplan out an extended trip with reservations? have the moon book, read Fodors and have the Benchmark map book. trying to locate a copy of the AAA Indian Country guide. any and all recommendations and insights appreciated.
