The
Quinault River ( or ) is a long
river located on the
Olympic Peninsula in the
U.S. state of
Washington. It originates deep in the
Olympic Mountains in the
Olympic National Park. It flows southwest through the "Enchanted Valley". Several miles above
Lake Quinault the river is joined by its main tributary, the North Fork Quinault River. The
main stem Quinault River above this confluence is sometimes called the East Fork Quinault River. Below the confluence the river marks the boundary of Olympic National Park for several miles before emptying into Lake Quinault. After the lake, the Quinault River flows southwest, reaching the
Pacific at
Taholah. From Lake Quinault to the ocean, the river is contained within the
Quinault Indian Reservation.
