If you're going up/down the east side of the Sierra Nevada - there's a not much used beauty to be seen: Bristlecone Pine/White Mountains recreational area - located just off Hwy US 395 near Big Pine, CA. Check http://www.sonic.net/bristlecone/WhiteMts.html . You will climb on adequate 2wd roads from four thousand past campgrounds at seven and ten thousand with a final destination of Patriarch Grove (no camping there) at 11,200. There are Bristlecones up there that are still alive and are three and four thousand years old. Remarkable quiet, isolation and views back across the Owens Valley at the High Sierra and Mt. Whitney. The White Mountains peak out at 14,000. Conde Nast magazine - purportedly THE travel magazine of the Western World - called the stretch from Tahoe south on Hwy 395 along the East slope of the High Sierra the most beautiful continuous 300 miles in North America.
