Sick of the shoulder-to-shoulder crowds of the Yosemite Valley at peak times? Head to the high country and stay at Tuolumne Meadows Campground. I lucked out and snagged a walk-up spot in early summer, when it was still showing closed for reservations online, but was actually open.  Quiet, full of trees, bear boxes at every site, bathrooms with flushing toilets, water, lots of nice hiking trails nearby, and not nearly the crowds of the valley floor.
