I went on a solo backpacking trek on the Pacific Crest Trail, heading southbound out of Kennedy Meadows and arriving in Walker Pass four days later. This is one of the driest sections of the PCT, and I hiked it during a dry year, but luckily it was early enough in the season that drinking water was readily available. The northern section was forested and the southern part was mostly chaparral, but both were beautiful in their own way.
