Yosemite Park: The most visited National Park - need we say more? This small wondrous granite walled valley has been converted into main stream concessionaire, equipped with pizza shops & galleries. Maybe the big floods are natures way of keeping people out. Either way, you best reserve a campground or lodge (a year in advance) if you plan an overnight in the Yosemite Valley, any time of the year. Accommodations can also be found in the neighboring towns around the National Park. Historic Gold Country on the west side and the dramatic high desert w/ Mono Lake on the east. Tioga Pass closes annually for snow, more than half the year.
