Utah - Rough Guides Professional Review and Guide
"With the biggest, most beautiful and most pristine landscapes in North America, Utah has something for everyone: from brilliantly colored canyons, across endless desert plains, to thickly wooded and snow-covered mountains. This unmatched range of terrain, almost all of which is public land, makes Utah the place to come for outdoor pursuits, whether your tastes run to hiking, off-track mountain biking, whitewater rafting or skiing.
Southern Utah has more national parks than anywhere else in the US; in fact it has often been suggested that the entire area should become one vast national park. The most accessible parts – such as Zion and Bryce Canyon – are by far the most visited, but lesser-known parks like Arches and Canyonlands are every bit as dramatic. Huge tracts of this empty desert, in which beautiful pre-Columbian pictographs and Ancestral Puebloan ruins lie hidden, are all but unexplored; seeing them in safety requires a good degree of advance planning and self-sufficiency."
