If you're going to do Yosemite, get a spot in Tuolomne meadows or go to Hetch Hetchy. Should be way easier than in the valley.
Either that or go to Sequoia and Kings Canyon. Way easier to find camping if you don't want to do the whole backpacking thing (I've camped in free sites a bunch of times) and Kings Canyon is like Yosemite without the crazy crowds.
(I mean, really... most people would mistake this as Yosemite, anyways)
And you have way sicker peaks...
Either that, or do Eastern Sierra zones, where there are like 14 different 14ers, and countless 13ers and 12k peaks. North Palisade is my favourite...
Have a nice day, Bluename.
