The route begins at U.S. Route 101 near Klamath and after a discontinuity from Klamath Glen (near the McBeth Airport) to Johnsons via the Yurok Indian Reservation, resumes at the town of Wautec. The highway continues through Pecwan before the curving road heads southeast and passes through Martins Ferry after several miles. SR 169 ends at State Route 96 near Weitchpec. The entire route is within the Yurok Indian Reservation.
SR 169 is not part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration.
