You can drive to Alaska from California, but it takes 30 to 36 hours of actual driving spread over several days, costs $800 to $1,400 in fuel alone, and requires crossing through Canada on a valid passport or passport card.
The Alaska Highway starts in British Columbia and runs 1,387 miles to Delta Junction, Alaska. From California, you'll drive north through Oregon and Washington, cross into Canada at the Washington-British Columbia border, then follow the Alaska Highway northeast into Alaska. The total distance from San Francisco to Anchorage is roughly 2,100 miles; from Los Angeles, it's closer to 2,350 miles. Most drivers break this into a four- to five-day trip.
This is not a casual weekend drive. You'll spend money on fuel, lodging, food, and vehicle maintenance on a remote highway where services are sparse and prices are high. You'll also need to plan around border crossings, vehicle documentation, and the reality that help is far away if something breaks.
Key Takeaways
- The drive from California to Alaska covers 2,100 to 2,350 miles and takes 30 to 36 hours of driving, typically split across four to five days.
- Fuel costs range from $800 to $1,400 depending on your vehicle's fuel economy and current gas prices, which are higher in remote areas of Canada and Alaska.
- You must carry a valid passport or passport card to cross the US-Canada border; a driver's license alone is not sufficient.
- Vehicle maintenance, lodging, and food add $1,500 to $2,500 to the total trip cost, and services become scarce once you leave major towns.
- The Alaska Highway has limited cell service, no fuel stations for stretches of 100+ miles, and winter driving conditions from September through May that can close sections without warning.
What Documents You Need at the Border
You need a valid passport or passport card to cross from the United States into Canada. A state-issued driver's license is not enough. If you have a passport book, bring it. If you only have a passport card, that works too. If you have neither, you'll need to explore for one before you leave — passport processing takes four to six weeks for standard service.
Your vehicle also needs proof of ownership and current registration. Bring the title or registration document. If the vehicle is financed or leased, bring the lender's or lessor's permission letter; some border agents ask for it, some don't, but having it prevents delays. Your auto insurance policy should also cover you in Canada — most US policies do, but call your insurer to confirm before you cross.
If you're traveling with children, each child needs their own passport. A birth certificate alone is not sufficient for border crossing. If you're traveling with someone else's child, bring a notarized letter from the parent or guardian authorizing the trip.
Fuel Costs and Where to Fill Up
Fuel economy on the Alaska Highway is worse than on flat interstate driving because the road is hilly, often unpaved, and you'll be driving slower. Expect to lose 15 to 25 percent of your normal fuel economy. A vehicle that gets 25 miles per gallon on the highway might get 18 to 21 miles per gallon on the Alaska Highway.
Gas prices in remote British Columbia and the Yukon are 30 to 50 percent higher than in California. In late 2024, fuel in northern British Columbia was running $1.40 to $1.60 per liter (roughly $5.30 to $6.05 per gallon in US terms). Prices in Alaska are similarly high. Budget $800 to $1,400 for fuel depending on your vehicle size and current prices.
Fuel stations are not evenly spaced. Between Fort St. John and Watson Lake in the Yukon, you can drive 150 miles without seeing a station. Between Watson Lake and Whitehorse, it's another 170 miles. Always fill up when you see a station, even if your tank is half full. Carry a spare five-gallon fuel container if your vehicle's range is under 300 miles.
Lodging and Food on the Route
You cannot drive 2,100 miles in one stretch. Most drivers stop after 8 to 10 hours of driving per day, which means four to five nights on the road. Lodging in small towns along the Alaska Highway ranges from $80 to $150 per night for a basic motel room. In larger towns like Whitehorse or Fort St. John, you'll pay $120 to $200. Budget $400 to $750 for lodging depending on how many nights you stop.
Restaurants in remote areas charge $15 to $25 for a basic meal. A fast-food burger might cost $12 to $14. Grocery stores exist in most towns, but prices are 20 to 40 percent higher than in California. If you're traveling with others or on a tight budget, buying groceries and cooking in your hotel room or at a campground saves money. Campgrounds cost $20 to $40 per night and are common along the route.
Budget $300 to $500 for food over four to five days, depending on whether you eat at restaurants or buy groceries.
Vehicle Maintenance and Repair Costs
The Alaska Highway is rough on vehicles. Gravel sections, potholes, and washboard surfaces wear tires faster and can damage suspension components. Before you leave, have a mechanic inspect your tires, brakes, suspension, and battery. If your tires are worn, replace them before you go — a tire blowout 200 miles from the nearest town is expensive and dangerous.
Budget $200 to $400 for preventive maintenance before the trip: an oil change, tire rotation, fluid top-offs, and a battery test. Carry spare belts, hoses, fuses, and a basic tool kit. If something breaks on the road, repair costs are high because labor is expensive in remote areas and parts must be ordered from larger towns. A straightforward repair that costs $150 in California might cost $300 in Whitehorse.
Consider purchasing roadside information coverage before you leave. Some auto clubs offer coverage in Canada and Alaska; others don't. Verify your coverage includes towing in remote areas and that the tow distance is unlimited or very high.
Seasonal Driving Conditions and Timing
The Alaska Highway is open year-round, but winter driving (October through April) is dangerous. Snow, ice, and whiteout conditions are common. Daylight hours are extremely short — in December, you'll have only 5 to 6 hours of daylight in the Yukon. Summer (June through August) is the safest and most popular time to drive, with long daylight hours and mostly clear roads, though rain is frequent.
Spring (May) and fall (September) are transitional. Roads are usually passable, but weather can change quickly. Sections of the Alaska Highway occasionally close due to avalanches, washouts, or severe weather. Before you leave, check the Alaska Department of Transportation website and the Government of Yukon website for current road conditions. If a section is closed, there is no alternate route — you wait or turn back.
Plan your trip for June through August if possible. If you must travel in shoulder seasons, leave extra time and carry emergency supplies: blankets, a first-aid kit, flares, jumper cables, and extra food and water.
Cell Service and Emergency Resources
Cell service is nonexistent for long stretches of the Alaska Highway. Between Fort St. John and Whitehorse, you'll have no signal for 100+ miles at a time. Some vehicles have satellite communicators or emergency beacons; if you're traveling alone or in a remote area, consider renting or purchasing one.
If your vehicle breaks down, flag down another driver or walk to the nearest town. The Alaska Highway is traveled regularly, so you will eventually see another vehicle, but it might take hours. Carry extra water, snacks, and a charged phone battery. Tell someone where you're going and when you expect to arrive; if you don't check in, they can alert authorities.
Hospitals are in larger towns only: Fort St. John, Whitehorse, and Fairbanks. If you're injured or seriously ill in a remote area, evacuation by helicopter is possible but extremely expensive — $5,000 to $15,000 or more. Travel insurance that covers medical evacuation is worth purchasing.
Total Cost Estimate for the Trip
| Expense | Low Estimate | High Estimate |
|---|---|---|
| Fuel (2,100 miles) | $800 | $1,400 |
| Lodging (4 nights) | $320 | $800 |
| Food | $300 | $500 |
| Preventive maintenance | $200 | $400 |
| Passport (if needed) | $130 | $165 |
| Total | $1,750 | $3,265 |
These figures assume you're driving a mid-size sedan or SUV with reasonable fuel economy and staying in budget motels or campgrounds. If you drive a large truck or RV, fuel costs will be significantly higher. If you stay in nicer hotels or eat at restaurants for every meal, lodging and food costs will double.
Frequently Asked Questions
Do I need an International Driving Permit to drive in Canada?
No. Your valid US driver's license is sufficient to drive in Canada. An International Driving Permit is optional and not required by Canadian law, though some car rental companies ask for one. If you want one, you can obtain it from the American Automobile Association (AAA) before you leave.
What if my vehicle breaks down in the middle of nowhere?
Stay with your vehicle. It's easier for rescuers to spot than a person walking. Turn on your hazard lights, stay hydrated, and wait for another driver or for someone to report you missing. If you have cell service, call for help. If not, flag down the next vehicle that passes. The Alaska Highway has regular traffic in summer; you won't be stranded indefinitely.
Can I tow a trailer or RV on the Alaska Highway?
Yes, but the road is rough and narrow in places. Large RVs and trailers are common on the Alaska Highway in summer, but you'll drive slower and use more fuel. Some sections have tight curves and steep grades. If you're towing, inspect your trailer's tires and brakes before you leave, carry extra water for cooling, and plan for longer driving days because you'll move slower.
What's the cheapest time of year to make this drive?
Late May and early September have lower lodging prices than peak summer (July and August) and better weather than winter. Fuel prices don't vary much by season, but lodging in Whitehorse and other towns can be 20 to 30 percent cheaper in shoulder seasons. The trade-off is that weather is less predictable and daylight hours are shorter.
Do I need to book lodging in advance?
In peak summer (July and August), yes. Popular towns like Whitehorse and Fort St. John fill up quickly. In shoulder seasons and winter, you can usually find a room by calling ahead a day or two. Campgrounds rarely require advance booking except in peak summer.
