Sequoia National Park is a national park located in the southern Sierra Nevada, east of Visalia, California, United States. Created in 1890, it was the third to be created after Yellowstone National Park and the now disappeared Mackinac Park. The park covers an area of 1635 km². A characteristic feature of this park is the famous forest of giant sequoia, which includes General Sherman. It's the largest tree in the world, known for its spectacular height. It is 84 m high and 11 m in diameter, and so far has lasted 2200 years. The largest branch has a diameter of about 2 m. This tree is also the most voluminous in the world, with a 1 ton trunk and a base with a 31m circumference! Inside the park is Mount Whitney, the highest peak in the U.S. outside Alaska, with a height of 4418 m. Be careful in winter, chains must be used. At the bottom of the mountain it can seem the weather is OK, but all that can change as you climb.
