Kennewick, WA → Kelowna, BC

The drive from Kennewick to Kelowna takes you on a straightforward journey of approximately 255 miles that typically takes just over five hours. You'll begin by heading north from Kennewick on Interstate 90, which carries you through the semi-arid landscape of central Washington before merging onto US Route 395 near Spokane. From there, you'll continue northward through increasingly forested terrain as you approach the Washington-Idaho border, eventually transitioning to US Route 97 as you head toward the Canadian border near Oroville, Washington. The final stretch involves crossing into British Columbia and following Highway 97 north into Kelowna, a scenic route that becomes noticeably more mountainous and verdant as you progress.

As you travel this corridor, you'll witness a dramatic transformation in landscape that reflects the region's diverse geography. The initial stretch through the Kennewick area features the dry, rolling terrain characteristic of the Columbia Basin, but once you head into the forested zones north of Spokane, the scenery becomes increasingly lush. Elevation changes are gradual but noticeable as you climb toward the British Columbia interior, and you'll gain roughly 1,500 feet in elevation by the time you reach Kelowna. The drive passes through small towns like Colville, Washington, which serve as charming waypoints before you enter the more mountainous landscape of British Columbia's Okanagan region.

The best time to make this drive is late spring through early fall, when all mountain passes are reliably open and visibility is excellent. Winter driving can be treacherous on this route, particularly once you enter British Columbia, where snow and icy conditions frequently impact Highway 97. Summer offers ideal conditions with long daylight hours, though you should account for occasional logging trucks and increased traffic near Kelowna. Spring and fall provide excellent compromises, with pleasant temperatures and lighter traffic, making these seasons ideal for enjoying the scenic countryside at a relaxed pace.
