Bishop is a lovely town in the Eastern Sierras with everything a hiker could need: restaurants, some affordable motels, laundromat, grocery stores, some outfitters for ultralight gear and even a small old-fashioned cinema with great atmosphere.
If you are hiking the Pacific Crest Trail, it is a nice place to spend a zero day. Hiking northbound, there are two options to get to Bishop. At Bishop Pass Trail, hike 12 miles to South Lake and hitchhike 19 miles to Bishop. Or take the Piute Pass Trail 24 miles farther, hike for 18 miles to North Lake and hitchhike 18 miles to Bishop.
