General Grant National Park was established October 1, 1890, one week after Sequoia National Park, to protect a single grove of giant sequoias. On March 4, 1940, Congress created Kings Canyon National Park, absorbing General Grant into it as Grant Grove.
The merged park has been administered jointly with Sequoia National Park since 1940. NPS gives the combined parks at 865,964 acres, of which Kings Canyon's share is 461,901 acres.
The park spans two districts: Grant Grove, home to the General Grant Tree, and Cedar Grove, reached by road along the South Fork Kings River, where the canyon the park is named for opens out.
