Location Details/Description: Yosemite National Park (YOSE), Mariposa County, CA

Not just a great valley, but a shrine to human foresight, the strength of granite, the power of glaciers, the persistence of life, and the tranquility of the High Sierra. First protected in 1864, Yosemite National Park is best known for its waterfalls, but within its nearly 1,200 square miles, you can find deep valleys, grand meadows, ancient giant sequoias, a vast wilderness area, and much more.

Nearest communities for shopping, doctors, hospitals, and other amenities are Yosemite Valley, Mariposa, or Oakhurst with the cities of Fresno or Merced being two hours away. Yosemite National Park is fairly remote.

It is recommended that applicants have a personal vehicle, but public transit is available via YARTS (https://yarts.com/). Additionally, there is limited cell-phone service in the park. Limited internet connectivity is available at some of the cafes and hotels in the park.
