Did you know that some towns in Alaska are only accessible by boat or plane? Even Glacier Bay National Park and Preserve and the capital city of Juneau are cut off from the rest of the state. For locals and tourists, the Alaska Marine Highway System is the only option for traveling and moving goods.

Let’s learn more about this ferry system so you can plan your Alaskan getaway!

Some places in Alaska aren’t accessible except by boat or plane. The Alaska Marine Highway System provides dependable transportation of people, goods, and vehicles to over 30 communities across 3,500 miles of coastline.

The ferries travel from Bellingham, Washington, to Dutch Harbor in the Aleutian Chain. The Alaska ferry system provides a unique opportunity for travelers to experience the rugged coastal landscape, diverse culture, and recreational activities.

The Alaska Marine Highway System began in the late 1940s when Steve Homer, Ray Gelotte, and Gustav Gelotte bought an ex-U.S. Navy landing craft and started Chilkoot Motorship Lines. Tee Harbor, Haines, and Skagway were the first locations with ramps for transporting people, goods, and vehicles.

About a decade later, the company faced bankruptcy, and the Territorial Government purchased it in 1951. In 1959, after Alaska became the 49th state, voters approved expanding this marine highway system, commissioning new vessels and docks throughout Southeast Alaska.

Today, the ferries travel along the entire southern coast of Alaska — from Bellingham, Washington, through Ketchikan, then Junuea, over to the Kenai Peninsula, and finally all the way west to the Aleutian Islands.

The Alaska ferry system provides connections to otherwise remote and isolated communities. It includes popular tourist destinations like Gustavus, the gateway to Glacier Bay National Park, and Whittier, which sits along Prince William Sound, in the route.

The men who started the Alaska Marine Highway began with one ex-U.S. Navy landing craft, which soon proved too small. Today, there are four mainline vessels and five day boat and shuttle ferries.

The mainline vessels are the largest ships capable of carrying large shipping containers. They typically take more than a day to travel between start and end ports. Day boats and shuttles connect the smaller communities along the route.

All vessels in the Alaska ferry system have different vehicle requirements. Although they are all capable of moving vehicles, the size limitations vary. When you make reservations, it’s critical to communicate the accurate overall length of your vehicle or combined vehicles.

The Alaska ferry system transports standard vehicles, oversized vehicles, motorcycles, RVs, towed vehicles like campers and trailers, unaccompanied vehicles, and commercial vehicles.

If you travel with your RV aboard a ferry, you cannot sleep, eat, or lounge inside the vehicle while the vessel moves because there is no access to the car deck. You won’t find any hookups on board, and you must turn off propane bottles before boarding.

Animals must remain on the car deck during travel. Pets must stay in a travel carrier or remain in the vehicle. Because access to the car deck is restricted while the ferry is moving, there are 15-minute pet checks permitted every eight hours.

They will escort owners to the car deck to attend to their pets. However, owners can visit the car deck anytime the vessel docks at a port. Owners must also bring a health certificate for dogs or cats. To learn more about traveling with pets in Alaska, check out the Division of Environmental Health website.

If traveling without a vehicle, you must check in two hours before departure in Bellingham and Juneau. All other ports require check-in one hour before leaving. There is a security inspection at each port, and all guests must be on board 15 minutes before departure.

If you’re traveling with a vehicle, you must arrive earlier. They will board vehicles in specific lanes for efficiency, so make sure to arrive at your scheduled time. Depending on the port, you may check in three hours before departure or only one hour before leaving.

Americans only need to show a government-issued ID such as a driver’s license, passport, or military ID if they travel within U.S. ports. You must show a valid passport if traveling from a Canadian port to a U.S. port or visa versa. U.S. residents who aren’t citizens must provide their alien registration receipt cards.

Depending on which vessel you board along the Alaska Marine Highway System, there are opportunities for overnight stays. Cabins provide single or double bunk berths, and most have private bathrooms. They’re sold per trip and not per person or per night. Not every vessel has cabins or public showers.

You can camp in tents on the upper decks of all vessels. There are also recliner lounges where guests can sleep. So you can bring a small tent and sleeping bag aboard any ferry that travels the Alaska Marine Highway.

Just like airfares vary depending on location and length of flight, ferry rates also vary. Although they suspended dynamic pricing for 2023, the Alaska Marine Highway System has used it in the past as availability decreased. Regardless, the best rates are available the earlier you book your reservations.

Here are a few examples. Two adults traveling in a 30-foot motorhome from Bellingham to Juneau on a Friday during the summer months will pay almost $4,300. Two adults and three children traveling without an RV on the same ferry will pay a little over $1,600.

One adult with a standard vehicle traveling on the same ferry will pay almost $1,600. If you also choose to rent a cabin, it will cost anywhere from $523 to $800 more.

The Alaska Marine Highway is America’s only marine route designated a National Scenic Byway. It’s a fantastic way to see the rugged landscape of Alaska’s coastline and visit these small fishing communities. But it’s not cheap. Even if you’re traveling without a vehicle, it will cost around $450 to $500 for a trip.

But it’s an unforgettable adventure as you meet other travelers and locals, shop and dine in small coastal communities, and enjoy numerous recreational activities.
