Portland, OR → Kelowna, BC

Your journey from Portland to Kelowna takes you through some of the Pacific Northwest's most dramatic scenery as you travel approximately 335 miles northeastward. The route primarily follows Interstate 84 east from Portland along the Columbia River Gorge, a spectacular canyon carved by ancient floods, before transitioning to US Highway 97 near the town of Biggs, Oregon. From there, you'll continue north through central Washington on Highway 97, crossing into British Columbia where the route becomes Highway 97 North all the way to Kelowna. This six-and-a-half-hour drive is remarkably straightforward in terms of navigation, though it demands your attention through several distinct geographical zones and elevation changes.

The landscape transforms dramatically as you progress northeastward. After leaving the lush, urban Portland metro area, you'll experience the stunning Columbia River Gorge with its towering basalt cliffs, waterfalls, and evergreen forests—a UNESCO-designated scenic area that's worth lingering in if you have time. As you head inland on Highway 97, the terrain gradually transitions from forested valleys to high desert plateaus, particularly noticeable as you pass through central Washington's drier climate. Elevation steadily increases, rising from sea level to over 3,500 feet by the time you reach Kelowna, so you'll notice the vegetation shifting from dense coniferous forest to sagebrush scrubland and eventually to the lake-dotted, semi-arid landscape of British Columbia's interior.

You'll pass through several notable communities including Hood River, Oregon—famous for windsurfing and scenic viewpoints—and the small town of Chemult near the Washington-Oregon border. The Washington portion includes some lovely rural stretches with agricultural areas and small towns before you cross into Canada and approach the Okanagan region's wine country and recreational lakes. Plan for a more challenging drive during winter months, particularly from November through March, when I-84 through the Gorge and Highway 97 in British Columbia can experience snow, ice, and reduced visibility. Spring through fall offers the most pleasant conditions, with summer providing clear roads and expansive views, though afternoon thunderstorms are possible in the higher elevation sections. Keep in mind that you'll need proper identification for the US-Canada border crossing near Oroville, Washington

Seasonal Driving Considerations
