No road connects Juneau to the rest of Alaska or the continental United States

Juneau is not reachable by car. There is no highway, no gravel road, and no seasonal route that connects the city to Anchorage, the Alaska Highway, or any other road network. Juneau sits on an island in Southeast Alaska's Inside Passage, surrounded by water and mountains. The only ways in are by plane, ferry, or boat.

This is not a recent change or a temporary closure. Juneau has been road-isolated since its founding in 1880. The geography that makes it isolated — deep fjords, glaciers, and rugged terrain — is the same geography that makes it one of Alaska's most visited destinations. If you are planning a trip and assumed you could drive there, you need to change your transportation plan before you book lodging or activities.

Key Takeaways

  • Juneau has no road access; you must fly or take a ferry to reach it from anywhere else in Alaska or the continental US.
  • Alaska Airlines operates multiple daily flights from Anchorage and Seattle to Juneau, typically costing $150 to $400 one-way depending on how far in advance you book.
  • The Alaska Marine Highway System ferry from Ketchikan to Juneau takes about 6 hours and costs roughly $80 to $150 per passenger, but runs on a fixed schedule with limited sailings per week.
  • You can drive to Southeast Alaska ports like Ketchikan or Prince Rupert, BC, then ferry to Juneau, but this adds 12 to 24 hours to your travel time.
  • Once in Juneau, you do not need a car; the downtown area is walkable and local tour operators provide transportation to glaciers and other attractions.

Flying to Juneau is the fastest and most common route

Alaska Airlines operates the majority of flights into Juneau International Airport (JNU). From Anchorage, flights take about 1 hour and typically depart multiple times daily. From Seattle-Tacoma International Airport (SEA), flights take about 2.5 hours and usually have at least one daily departure. Prices vary widely by season and how far ahead you book — expect $150 to $250 one-way in shoulder seasons (May, September) and $250 to $400 in peak summer (June through August).

Book directly through Alaska Airlines or through standard travel search engines like Google Flights, Kayak, or Expedia. Juneau's airport is small but modern, and ground transportation into downtown is straightforward: taxi, rental car, or ride-share services operate from the terminal. The flight is the most predictable option if you have a fixed arrival date and do not want to coordinate with ferry schedules.

The Alaska Marine Highway ferry is cheaper but slower and schedule-dependent

The Alaska Marine Highway System operates the MV Matanuska and MV Taku ferries on the Inside Passage route. From Ketchikan to Juneau, the journey takes approximately 6 hours. One-way fares are roughly $80 to $150 per adult passenger, depending on the season and cabin type (deck passage is cheapest; inside cabins cost more). Vehicles can be transported, but a car is not useful in Juneau itself.

The ferry schedule is not daily. Sailings typically run three to five times per week during peak season (May through September) and less frequently in winter. You must check the Alaska Marine Highway website for current schedules and book in advance, especially in summer. The ferry is a good option if you are already in Southeast Alaska and want to move between towns, or if you prefer a slower, more scenic journey and have flexible dates.

Driving to a Southeast Alaska port, then ferrying to Juneau

If you want to drive part of the way, you can reach Ketchikan or Prince Rupert, BC by road, then take the ferry to Juneau. Ketchikan is about 1,400 miles from Seattle via the Alaska Highway and Cassiar Highway — roughly 20 to 24 hours of driving spread over two to three days. Prince Rupert, BC is about 1,100 miles from Seattle via the Yellowhead Highway — roughly 16 to 18 hours of driving over two days.

This route makes sense only if you want to explore Southeast Alaska by road first, or if you are traveling with a vehicle you plan to use in Juneau (which is rare, since Juneau is small and walkable). The ferry from either port to Juneau takes 6 to 10 hours depending on the route and vessel. Factor in ferry schedules, which may not align with your driving arrival time, and you could spend a day or more waiting in port.

You do not need a car once you arrive in Juneau

Downtown Juneau is compact and walkable. Most hotels, restaurants, and shops are within a 10-minute walk of the cruise ship docks and ferry terminal. Taxis and ride-share services (Uber and Lyft operate in Juneau) are available for longer distances or bad weather. If you rent a car, you will pay $50 to $80 per day for a vehicle you barely use.

For activities outside downtown — Mendenhall Glacier, the Juneau Icefield, hiking trails — local tour operators provide transportation. Most glacier tours include round-trip transportation from downtown as part of the package price. Fishing charters, whale-watching tours, and backcountry excursions all include pickup and drop-off. You can experience Juneau fully without ever renting a car.

Winter travel to Juneau is possible but less frequent

Flights continue year-round, though winter weather can cause delays. Alaska Airlines maintains service even in December and January, though you should expect higher prices and less predictable schedules. The ferry runs less frequently in winter — sometimes only two to three sailings per week instead of five — and weather can cause cancellations.

Winter in Juneau means shorter daylight hours (about 6 hours of daylight in December) and colder temperatures, but also fewer tourists and lower lodging prices. If you are flexible on dates, winter is cheaper. If you have a fixed arrival date, flying is more reliable than ferrying.

Frequently Asked Questions

Can I ship my car to Juneau and drive it there?

Technically yes, but it is impractical and expensive. The Alaska Marine Highway does transport vehicles, but shipping a car from Ketchikan to Juneau costs $300 to $500 and takes the same ferry time as a passenger. Once in Juneau, a car is unnecessary and parking is limited. Renting a car for the few days you might want one is far cheaper than shipping your own vehicle.

Is there a road being built to Juneau?

No. A road to Juneau has been proposed multiple times over decades, but the cost (estimated at $2 to $4 billion) and environmental impact make it unlikely. The terrain — glaciers, mountains, and water — makes construction extremely difficult. Juneau's isolation is permanent.

What if I get seasick on the ferry?

The Inside Passage ferry route is generally calmer than ocean crossings, but motion is still possible. Bring over-the-counter motion sickness medication (dramamine or ginger supplements) before boarding. The ferry cabins have windows and fresh air helps. If seasickness is a serious concern, flying is the better choice.

How much does it cost to fly to Juneau from Anchorage?

One-way fares typically range from $150 to $400 depending on season and how far in advance you book. Summer peak season (June through August) is most expensive. Booking two to four weeks ahead usually offers better prices than last-minute bookings. Check Alaska Airlines directly or use Google Flights to compare current prices.

Can I take a cruise ship to Juneau instead?

Yes. Juneau is one of Alaska's most popular cruise ship ports. If you book a Southeast Alaska cruise, Juneau is typically included as a port of call. This is a good option if you want a guided experience and do not want to arrange your own transportation, but it is more expensive than flying independently and you have less flexibility on how long you stay.
