Cannon Beach to Pullman: Ultimate Oregon-Washington Road Trip

The drive from Cannon Beach, OR to Pullman, WA covers roughly 450 miles (725 km) and takes about 7.5 to 8.5 hours of pure driving time, not counting stops. This route traverses the Coast Range, the Willamette Valley, the Cascade Mountains, and finally the rolling hills of the Palouse. A little-known fact: the town of Antelope, Oregon, once served as a base for the Rajneesh movement, and you'll pass near its remnants on Highway 97.

The journey begins on US-26 East from Cannon Beach, then connects to I-5 North, then I-84 East along the Columbia River, before cutting north on US-97 and then US-195 into Pullman. The route offers a stunning contrast of ecosystems—from misty coastal forests to high desert canyons and fertile wheat fields.

• Total distance: ~450 miles
• Driving time: 7.5–8.5 hours without stops
• Key highways: US-26, I-5, I-84, US-97, US-195
• Alternative: Add a day for detours to Mount St. Helens or the John Day Fossil Beds

Fuel stations are plentiful along I-5 and I-84, but become sparse on US-97 between Biggs Junction and Goldendale, and on US-195 between Pomeroy and Pullman. Plan to fill up in Portland, The Dalles, or Boardman. Gas prices in Oregon are typically lower than in Washington, so fill up before crossing the state line near Plymouth.

Road quality is excellent on all interstates, with well-maintained asphalt and clear signage. US-97 has some two-lane sections with moderate traffic. US-195 is mostly two-lane but in good condition, with few services for 60+ miles before Pullman.

• Best fuel stops: Portland (OR), The Dalles (OR), Pendleton (OR)
• Last fuel before Pullman: Pomeroy, WA (about 40 miles south)
• Tolls: No tolls on this route
• Roadside assistance: Available via AAA or mobile apps, but spotty cell coverage east of The Dalles

The journey starts in the temperate rainforest of the Coast Range, where moss-draped maples and towering Sitka spruce dominate. After crossing the Coast Range, you descend into the agricultural bounty of the Willamette Valley, known for its hazelnut orchards and vineyards. Near Woodburn, stop for fresh marionberries.

As you head east on I-84, the Columbia River Gorge unfolds with dramatic basalt cliffs and waterfalls. Multnomah Falls (Exit 31) is iconic, but less-crowded stops like Latourell Falls offer equally stunning views. Continue east to The Dalles, where the landscape shifts to high desert—sagebrush and wheat fields stretch to the horizon.

• Natural highlight: Columbia River Gorge National Scenic Area
• Best photo op: Rowena Crest viewpoint (c. 45.4112, -121.3472)
• Local commerce: Pendleton Woolen Mills (tours available) and farmers markets in season

This route is generally safe, but watch for: fog in the Coast Range, sudden rain in the Gorge, and high winds on I-84 near Arlington. In winter, snow can close US-97 over Satus Pass; check conditions. For families, the Oregon Museum of Science and Industry (OMSI) in Portland is a must, as is the Children's Museum in Richland (near Tri-Cities).

Pet-friendly stops include the Sandy River Delta (off I-84) for off-leash hiking, and the Maryhill Museum grounds (no pets inside, but gardens welcome leashed pups). Fatigue management: plan strategic breaks every 2 hours. Rest areas on I-84 near Cascade Locks and Biggs Junction have clean facilities. For a quiet nap, pull off at the John Day River viewpoints (gravel overlooks).

• Family: Portland Children's Museum, Pittock Mansion
• Pet: Sandy River Delta (Exit 18), Tom McCall Waterfront Park
• Rest zones: I-84 rest area at MP 63 (westbound), MP 100 (eastbound)
• Hidden gem: Stonehenge replica at Maryhill, WA (free, photogenic)
