The Grand Canyon is one of the wonders of the world. Its 277-mile length is protected by 1.2 million acres of national park. In this guidebook all the walking trails in Zion National Park and Bryce Canyon National Park are described. In Grand Canyon National Park, all the maintained and non-maintained rim-to-river trails and rim trails are covered as well. This guidebook also provides information on how to link together several trails in order to convert day-walks into long-distance walks. The fabulous views of nature's sculpture are known worldwide and are even better than our wildest imaginings. The walking trails are equally awesome. Many are serious endeavours only for the most experienced trekkers. The American South-West hosts a profusion of national and state parks and wildernesses. It boasts a seemingly endless variety of deep canyons, deserts high and low, snow-capped mountains and raging rivers. The Grand Canyon is only the largest of these canyons; the smaller Zion and Bryce National Parks are less famous, but lose nothing in comparison.
