State Route 153 (SR 153, named the Methow Valley Highway) is a 30.78-mile (49.54 km) long state highway in the U.S. state of Washington, serving as part of the Cascade Loop in Okanogan County. The Methow Valley Highway begins at an intersection with U.S. Route 97 (US 97) in Pateros at the confluence of the Methow River and the Columbia River. SR 153 travels northwest, parallel to the Methow River, to end at SR 20 south of Twisp. The highway was first established in 1897 as the Methow-Barron Road and was designated as various highways, including State Road 12 from 1905 to 1919, the Roosevelt Highway from 1919 to 1923, and Primary State Highway 16 (PSH 16) until the 1964 highway renumbering, when it became SR 153.
SR 153, part of the Cascade Loop, begins at an intersection with US 97 south of the confluence of the Methow River into the Columbia River in Pateros. The highway dips south before leaving Pateros into farmland and serving Alta Lake State Park to the south near the Chelan National Forest. SR 153 crosses the Methow River twice heading west towards the Sawtooth Ridge and turns north to the communities of Methow and Carlton. The highway continues northwest, ending at an intersection with SR 20 southeast of Twisp and Twisp Municipal Airport.
