You've probably looked at the map and figured it’s a straightforward six-hour shot. North on I-5, hang a right, and you're in wine country. Right?
Kinda. But honestly, if you just trust your default GPS settings for the trek from Seattle WA to Kelowna BC, you’re likely to miss the best views or, worse, end up stuck behind a semi-truck on a high-mountain pass during a surprise January whiteout. Driving to the Okanagan is a rite of passage for PNW locals, but the "best" way to get there changes wildly depending on the month, your patience for border lines, and whether you actually like driving.
The Driving Routes: It's Not Just About the Fastest Path
Most people default to the Coquihalla. It’s efficient. It’s fast. It’s also basically a giant paved conveyor belt through the mountains that can feel a bit soulless.
If you're leaving Seattle, you’ve got two primary "real" choices for the drive.
1. The "Fast" Route (I-5 to Highway 5)
You head north through Bellingham, cross at Sumas, and then catch Highway 1 toward Hope. From Hope, you jump on the Coquihalla (Highway 5). This road is legendary in BC. It’s a massive four-lane freeway that climbs to 4,000 feet. It is the fastest way to get to Merritt, where you then hop on the 97C (The Connector) into Kelowna.
Watch out for this: The Pennask Summit on the Connector sits at about 5,700 feet. Even if it’s a drizzly 45°F in Seattle, it can be a full-blown blizzard up there. As of early 2026, BC law still strictly requires winter tires (M+S or the mountain snowflake symbol) from October 1 to April 30 on these routes. Don’t risk it. I’ve seen enough SUVs in the ditch near the Big Bear snow tunnel to know the mountain doesn't care about your AWD.
2. The Scenic "Fruit Way" (The US-97 Route)
This is the "pro move" for summer. Instead of crossing near Vancouver, you drive east from Seattle on I-90 or US-2. You head toward Wenatchee and then go north on US-97 through Okanogan and Oroville.
Why do this?

- You cross the border at Osoyoos.
- The view as you descend into the Okanagan Valley from the south is breathtaking.
- You skip the high-altitude stress of the Coquihalla.
- You can stop for cherries and peaches in Penticton on the way up.
It adds maybe 45 minutes to an hour to the trip, but it’s a lot more relaxing. Plus, the border at Oroville/Osoyoos is usually way quieter than the chaos at Peace Arch or even Sumas.
Flying vs. Driving in 2026
Sometimes you just don't want to deal with the I-5 traffic. I get it.
The flight situation for Seattle WA to Kelowna BC has stayed pretty consistent, though prices fluctuate. Alaska Airlines and WestJet are the big players here. You’re looking at a flight time of roughly 1 hour and 15 minutes. It’s barely enough time for the flight attendants to hand out a Biscoff cookie before you're descending over the lake.
Typical pricing for a nonstop round trip sits between $170 and $430. If you see anything under $200, grab it. WestJet often runs deals that drop as low as $130, but those are usually "Basic" fares where you can't even bring a carry-on. Read the fine print.

Pro tip for flyers: Kelowna International (YLW) is small and efficient. You can usually get from the plane to a rental car in 20 minutes. But if you’re arriving in February, remember that YLW is prone to "fogged in" mornings. Flights get delayed frequently during winter inversions.
The Border: Don't Be "That" Traveler
The border is the great equalizer. It doesn't matter if you're in a Tesla or a beat-up Tacoma; a 90-minute wait at Sumas will ruin your mood.
As of 2026, the requirements haven't changed much, but people still mess them up.
- Passports are non-negotiable for air travel.
- For land crossing, Enhanced Driver’s Licenses (EDL) or NEXUS cards work great.
- If you're bringing the dog, you need proof of a rabies vaccination.
- Don't bring citrus or poultry across right now if there are active agricultural bans—check the CFIA (Canadian Food Inspection Agency) website the morning you leave.
Honestly, getting a NEXUS card is the smartest thing you can do if you plan on making this trip twice a year. The "Ready Lanes" at Sumas help, but the NEXUS lane is a literal time machine.
When Should You Actually Go?
Seattleites love Kelowna because it’s the "sunny version" of home.
Summer (June–August) is the peak. It’s hot. Like, 90°F hot. The lake is perfect, the wineries are buzzing, and the sun doesn't set until nearly 10:00 PM. But it's expensive. Hotels in downtown Kelowna or near the City Park will easily run you $350+ a night.
The "Sweet Spot" (September) is my personal favorite. The kids are back in school, the lake is still warm enough for a quick dip, and it’s harvest season for the vineyards. You get the sun without the "everything is crowded" vibe.
Winter (December–February) is for the skiers. Big White and SilverStar are world-class. If you’re heading from Seattle WA to Kelowna BC for a ski trip, just stay on the mountain. Driving back and forth from the city to the slopes every day gets old fast, especially with the morning ice on Highway 33.

Real Talk on Costs
Gas in BC is almost always more expensive than in Washington.
In early 2026, Seattle gas is hovering around $3.80–$4.10 per gallon. Once you cross the border and the pumps switch to liters and Canadian dollars, you’re effectively paying closer to $5.50 per gallon. Fill up in Bellingham or Sumas before you cross. Your wallet will thank you.
If you’re driving an EV, the network is solid. There are Tesla Superchargers in Abbotsford, Hope, Merritt, and Kelowna. Non-Tesla owners can rely on the BC Hydro EV network, which is surprisingly reliable, though you’ll want to download the app and set up your payment info before you lose cell service in the mountain passes.
Actionable Steps for Your Trip
- Check the Cams: Before you leave Hope, go to the DriveBC website. Look at the Coquihalla and Connector cameras. If it looks like a slushy mess, take Highway 3 (The Hope-Princeton). It’s lower elevation and often safer, even if it’s curvier.
- Download Offline Maps: There are massive dead zones between Princeton and Peachland. If you rely on live Google Maps, you might find yourself staring at a grey screen when you need to know which exit to take.
- Book Wineries in Advance: The days of just "rolling up" to a tasting room at Mission Hill or Quails' Gate are mostly gone. If you want a spot on the terrace, book it at least two weeks out.
- Exchange a Little Cash: While everywhere takes card, some of the best fruit stands in the valley are still "cash preferred" or use older terminals that can be finicky with US cards. Having $50 CAD in your pocket for a crate of peaches is a smart move.
- Border Timing: If you're driving on a Friday, try to hit the border before 2:00 PM or after 7:00 PM. The 4:00 PM to 6:00 PM window is a graveyard of idling engines.
The journey from Seattle WA to Kelowna BC is one of the best road trips in North America if you respect the terrain and timing. Just don't forget to switch your speedometer to kilometers once you cross—the BC Highway Patrol is not known for being lenient with "I forgot I was doing 120 in a 100 zone" excuses.
