You're standing on the boardwalk in Mission Beach, feeling that 72-degree San Diego breeze, and for some reason, you think: "I should go to the Arctic Circle." It sounds like a joke. Honestly, it's a 3,300-mile reality check that most people aren't actually prepared for.
Driving from San Diego to Fairbanks Alaska isn't just a long road trip. It is a psychological test. You are crossing three countries if you count the sovereign indigenous lands you'll pass through, multiple climate zones, and a whole lot of nothingness that can make a person go a little crazy.
Most travelers make the mistake of thinking this is just "The 5" to the "AlCan." It’s not. It is a grueling, beautiful, expensive, and occasionally terrifying traverse of the North American continent.
The Logistics of the San Diego to Fairbanks Alaska Run
Let's talk numbers because the scale of this is hard to wrap your head around. From the 805 North to the Richardson Highway in Fairbanks, you’re looking at roughly 55 to 60 hours of pure driving time. That’s not counting border crossings, gas stops, or the inevitable moment you have to wait two hours for a construction crew to let you pass a single-lane gravel patch in the Yukon.
Most people try to do this in ten days. You've gotta be kidding. Ten days means you're doing 330 miles a day, which sounds easy on paper until you realize that once you hit Northern British Columbia, your average speed drops significantly. Frost heaves are real. They will destroy your suspension if you try to maintain California freeway speeds.
Why the Route Choice Changes Everything
You basically have two main options once you clear the US border. You can take the Cassiar Highway (Hwy 37) or the Alaska Highway (Hwy 2).
The Cassiar is moodier. It’s narrower, has fewer gas stations, and puts you right in the teeth of the mountains. If you want to see bears, take the Cassiar. If you want a slightly more civilized experience with fewer chances of being stranded because a gas station owner decided to go fishing for the day, stick to the Alaska Highway starting in Dawson Creek.

Actually, speaking of Dawson Creek, don't confuse it with the 90s teen drama. It’s Mile 0 of the Alaska Highway. There is a big sign. You will take a picture with it. Everyone does.
The Reality of the "AlCan"
People talk about the Alaska-Canadian Highway like it's this mythical, dangerous dirt track. In 2026, it’s mostly paved. But "mostly" is a dangerous word.
The road is alive.
The permafrost underneath the asphalt melts and freezes, creating "frost heaves." Think of them like massive, invisible speed bumps that can launch a Subaru into the stratosphere. If you see red flags on the side of the road, slow down. Seriously.
Fuel, Food, and the "Yukon Tax"
Expect to pay a premium. Once you cross into Canada and start heading north of Prince George, prices jump. By the time you get to Destruction Bay or Whitehorse, you’ll be looking at fuel prices that make San Diego’s gas taxes look like a bargain.
- Gas Strategy: Never let your tank drop below half. It sounds paranoid. It’s not. Power outages can take out card readers at remote stations, or a fuel truck might be late.
- The Food Situation: You’ll eat a lot of mediocre burgers. Pack a cooler. If you can find a spot in Whitehorse called Wayfarer Oyster House, go there. It’s a weirdly sophisticated gem in a town that feels like a frontier outpost.
- Connectivity: Your fancy 5G plan? Forget it. You will have massive dead zones. Download your maps for offline use before you leave San Diego. If you don't, you'll be staring at a "No Service" bar while wondering if you missed the turn for the Top of the World Highway.
Crossing the Border: Don't Be That Person
Crossing from the US into Canada, and then back into Alaska at the Alcan Border station, is usually straightforward if you aren't an idiot.

They will ask about weapons. Do not try to bring a handgun into Canada. They don't care about your Second Amendment rights; they care about their laws. If you have a firearm, declare it, or better yet, ship it to an FFL in Fairbanks before you leave California.
Also, bear spray. You need it. But make sure it is labeled "Bear Spray" and not just "Mace." Canadian border agents are picky about that. They want to know you’re defending yourself against grizzlies, not humans.
What No One Tells You About Fairbanks
You finally roll into Fairbanks. You’ve crossed the 64th parallel. The air feels different—sharper, thinner.
Fairbanks isn't Anchorage. It doesn't have the ocean to moderate the temperature. In the summer, it can actually get hot—like 85 degrees hot—and the sun won't go down. It’s the "Midnight Sun" vibe. In the winter? Well, if you’re doing this drive in the winter, God help you. It can hit -40. At that temperature, steel gets brittle and tires get flat spots from sitting overnight.
The Mosquitoes
We need to talk about the "Alaska State Bird." The mosquitoes in the interior are not like the ones in San Diego. They are tactical. They are numerous. They will find the one patch of skin you didn't cover in DEET. If you stop to change a tire near a swampy area in the Yukon or near Fairbanks, you will be swarmed. Keep a head net in the glovebox. It looks stupid, but you'll be the one laughing while everyone else is slapping their own faces.
The Cost Breakdown (Roughly)
Traveling from San Diego to Fairbanks Alaska is a budget killer.

- Fuel: For a vehicle getting 20 MPG, expect to spend north of $800–$1,000 just on gas, depending on current exchange rates and northern surcharges.
- Lodging: Motels in the North are pricey for what they are. You’re paying for the location. Expect $150–$250 a night for a room that looks like it hasn't been updated since 1984.
- Maintenance: Budget for at least one new tire or a windshield chip repair. The gravel on the AlCan is brutal.
Is it Worth It?
Honestly? Yeah.
There is a moment somewhere in northern British Columbia, maybe near Muncho Lake—which is this unreal shade of turquoise—where you realize you haven't seen another car for forty minutes. You realize how big the world actually is. San Diego feels like another planet. The traffic on the 5, the crowds at La Jolla, the noise—it all just evaporates.
You see the Northern Lights if you’re there in late August or September. You see the vastness of the boreal forest. You see things most people only see on National Geographic.
Actionable Steps for Your Journey
If you’re actually going to pull the trigger on this, don't just wing it.
- Get a "The Milepost": It is the bible of North country travel. It’s a thick book that breaks down the road mile-by-mile. It tells you where the hidden pull-outs are and which gas stations are actually open.
- Check Your Spare: Not a "donut." A full-sized spare tire. And know how to change it on uneven gravel.
- Service Your Cooling System: The climb through the mountains can be hard on an engine, especially if you're loaded down with gear.
- International Paperwork: Ensure your passport is valid for at least six months beyond your travel dates. Even though it's a land border, they can be sticklers.
- Windshield Protection: Some people use "bug deflectors" or even temporary film. At the very least, make sure your insurance covers glass with a low deductible. You will get a rock chip. It’s a rite of passage.
The road from San Diego to Fairbanks Alaska is a transformation. You start as a Southern California commuter and you arrive as someone who knows exactly what it feels like to be very small in a very large world. Just watch out for the moose. They don't move for you; you move for them. Always.
