Today, we proceed to an exciting day ahead as we visit Yosemite National park. 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 tranquillity of the High Sierra. 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 and much more. Overnight in San Francisco.
