What should you know before visiting Historic Columbia River Highway?

No toll roads expected for a car. Mountain passes: Crater Lake Rim Drive (2,300 m, usually open July–October).

The road was built between 1913 and 1922 and its curves date from the era of early cars. With a large motorhome, check road conditions and restrictions beforehand.
Parking at the waterfalls is very limited, especially on weekends and holidays. In summer 2026 a timed-use permit applies to the Multnomah Falls lot at I-84 exit 31; rules change, so check with the Forest Service.
Only parts of the old road are open to cars; the rest is State Trail for bikes and walkers, such as the roughly 5-mile Twin Tunnels section near Mosier. Check a current map before you go.

The drive

The route starts at Troutdale on the edge of Portland. It passes the Portland Women's Forum viewpoint, Vista House at Crown Point and the falls at Latourell, Bridal Veil, Wahkeena and Multnomah. It continues via Cascade Locks and Hood River to Mosier, the Rowena Loops and The Dalles. Not every stretch is open to cars, and Interstate 84 runs alongside.

Planning

Allow more than the 3 to 5 hours of driving if you hike at the falls. TripCheck reports road conditions, and ReadySetGorge covers trails, several of which were affected by the 2017 wildfire. Parking is very limited, so with a large vehicle ask about access and parking beforehand, for example at Oregon Welcome Centers. Cascade Locks has campgrounds and services.
