The Klehini River is about long from its source in British Columbia to its mouth at the Chilkat River, of which it is the largest tributary. The Klehini River is renowned for its salmon runs, its biannual congregation of bald eagles—the second largest in the Haines area after the Chilkat River's Council Grounds—and for the Klehini Falls. The Klehini also delineates the northern boundary of the Chilkat Range.
