Sequoia National Park

Sequoia National Park is probably the only national park in the United States where it is a good idea to stretch your neck before entering. This is due to the fact that Sequoia National Park is home to some of the world's largest trees by volume. The park's main attraction, the General Sherman Tree, is the largest, standing 275 feet tall and 36 feet in diameter. This incredible tree, as well as others, can be found in the park's aptly named Giant Forest, one of several giant sequoia groves.

However, getting to all of this breathtaking natural beauty will take some effort. To get here, drive 80 miles southeast of Fresno, or nearly four hours from Los Angeles or San Jose, the closest cities with international airports. The Wuksachi Lodge (rates hover around $295 per night) and campgrounds are available on-site, with rates ranging from $22 to $70 per night depending on group size.
