Mother Nature seems to have stayed longer in some states than in others. In Utah - she was very busy. In order to see all of the incredible national parks - Bryce Canyon National Park, Arches National Park, Delicate Arch, Zion National Park, Canyonlands and Monument Valley, I recommend car camping. The national parks here offer a wide range of camping options - from primitive to full hooks ups with water and electricity. The best time of the year for this part of Utah is late May and early June - before the heat begins. At night it might be a bit chilly, but that's what a campfire is all about.
