The route
This verified 201-mile loop begins at Troutdale, climbs the drivable western Historic Columbia River Highway through Crown Point and the Waterfall Corridor, then uses Interstate 84 through Cascade Locks to Hood River. From there, it loops through the Hood River Valley before following Oregon 35 and US 26 around Mount Hood, including the signed Timberline Road spur.
Three days give the route room to breathe: one for waterfalls and the Gorge, one for orchards and wineries, and one for the mountain circuit. The landscape changes from mossy basalt and waterfalls to dry eastern Gorge slopes, cultivated valley rows and high alpine forest.
Access is not static. The Interstate 84 Multnomah Falls lot requires a timed-use permit between 9 a.m. and 6 p.m. from May 22 to September 7, 2026, while Vista House can close for high heat or strong wind. Check ODOT TripCheck, the official Multnomah Falls guidance and Timberline conditions immediately before departure.
