Kings Canyon National Park is adjacent to Sequoia National Park and the two are usually mentioned at the same time, as in "Sequoia and Kings Canyon National Parks." Kings Canyon is largely a wilderness park, with only two relatively small sections accessible by cars.
We spent most of our time near the Cedar Grove Visitor Center after driving Highway 180 (a twisty-turny scenic byway) through the steep-walled Kings Canyon to Roads End. The other popular section of the park adjoins Sequoia National Park and contains Grant Grove and Redwood Mountain Grove, two large areas of sequoia trees.
