So I'm going this year from July 9th-14th and I understand that the summer is the busiest time for Yosemite, but what exactly does it mean to be busy there? I used to work in a theme park so I know it means to be busy there with 40,000+ people. I work in a restaurant so when my coworkers say that lunch was "slammed," I know exactly what that means. But what exactly does it mean for yosemite to be crowded? I've never been there before so I have no idea what to expect as far as crowds on trails or things to do and whatnot but I understand there are shuttles that take you to trailheads and such. Does this mean it might take hours for the shuttle? That anything that requires a reservation will not be available? I arranged my schedule specifically for this time because last year I went camping in Silver Lake at the end of June and there was a late winter in the Sierras in 2011. The drive across one of the mountain roads over the Sierras was kind of scary with snow at the top and a sharp descent. It was pretty freezing at night and snow covered some mountain tops. It was still a great experience, but the late winter gave us really cold weather at night and a scary mountain drive and I wanted to drive and bypass that so I don't have to pack as much.
Can anyone tell me of their mid summer experiences?
