Yosemite National Park is the second oldest park in the United States, and one of the most famous. It is located within California’s Sierra Nevada mountains, and covers over one thousand square miles. Millions of tourists visit the park every year, though the majority explore no further than Yosemite Valley, the park’s iconic site. The valley is home to famous rock formations such as El Capitan, Sentinel Dome and Half Dome. Beyond the packed trails of the valley are vast expanses of designated wilderness through which hundreds of miles of trails run. During peak summer months, expect long lines and little parking in Yosemite Valley.
