Yosemite National Park is one of the most beautiful national parks in the western United States. It is as famous as Yellowstone Park and Grand Canyon. In order not to go back, I drove through Death Valley from Peggy. On the first day, I drove 10 hours to Mono Lake. I lived near Mono Lake. The next morning, I drove into Yosemite National Park, where I could stay and play easily. There are free public buses in the scenic area. The buses have three routes, which are distinguished by color: orange, green and purple. They go to three different sightseeing areas. Of course, some stations in the middle of the way can transfer to different colored lines, just like subway stations. Each route contains more than a dozen to twenty stops. Each stop is a scenic spot. Tourists can choose their favorite stop to get off and play according to their own wishes. After the end of the tour, they can wait for the next bus to go on. It is very convenient.
