Sequoia National Park is the country's second oldest national park (Yellowstone was the first). From atop Moro Rock you can get a good overview of the park (after climbing 400 or so steps). To the north lies the biggest tree in the world: the General Sherman Tree. While the California coastal redwoods might be taller, sequoias are bigger around and weigh more. To the east are the high Sierras, where peaks up to 13,802 feet are visible (Mount Whitney, at 14,494 feet is just out of sight).
