Further north of the ranch is the parking lot for the Umtanum Creek Recreation Area, with a network of hiking trails connected via a footbridge over the Yakima River. After completing a series of hairpin turns along the narrowest section of the valley, SR 821 is rejoined by the railroad and enters the wide Kittitas Valley near several vineyards. The highway turns east at Helen McCabe State Park onto Thrall Road and crosses Wilson Creek before terminating at a partial cloverleaf interchange with I-82 and US 97. From the junction, Canyon Road continues north along the railroad to an interchange with I-90 and into downtown Ellensburg.
