Hiking the John Muir Trail was the experience of a lifetime. The diary is a personal account, with photos, of life on the trail in the High Sierra, California, during 20 days in with a group of fellow backpackers. The hike through the Range of Light, in the words of John Muir, follows beautiful forested valleys, crosses spectacular mountain passes and ends in a night hike to the summit of Mt Whitney, 14,495', to watch the dawn break.
