"...I decided to visit California for a year or two to see its wonderful flora and the famous Yosemite Valley. All the world was before me and every day was a holiday, so it did not seem important to which one of the world's wildernesses I first should wander."
--John Muir (1868)
This is such a scenic park, and very compact so walking just short distances brings you to scenic vista after scenic vista. They are having a heat wave (in the 90's in San Francisco), so up here it is an unseasonable 75-80 degrees and beautifully sunny.
