Embarking on a coast-to-coast motorhome journey is the pinnacle of road-tripping. The Great Northern route from Seattle to Boston covers an incredible 6,995 km, offering an unmatched cross-section of North America. Traveling by RV is the perfect way to tackle this massive distance because it allows you to embrace the philosophy of slow travel. Instead of rushing from hotel to hotel, your rolling home provides consistency and comfort as the landscapes shift dramatically outside your window.
This specific itinerary is brilliant because it weaves through the rugged Pacific Northwest, crosses the expansive northern plains, hugs the shores of the Great Lakes, dips into the rich cultural tapestry of Canada, and concludes in historic New England. You have the flexibility to cook your own meals, pull over at a scenic viewpoint in Montana, or take your time exploring the deep forests of Michigan. For specific campground recommendations and detailed routing, check the comprehensive itinerary inside RV PLANET.

This 6,995 km journey is packed with diverse attractions. Based on the highlights of this route, here is a taste of what you will encounter:
The transition of landscapes is the star of the show. Early in your trip, you will be stunned by the views at Snoqualmie Falls in Washington. As you move into Canada, you can relax at the amazing Petrie Island Beach in Ontario and find yourself flourishing amidst the incredible flora at the Montreal Botanical Garden in Quebec. Expect to encounter everything from caves and botanical gardens to expansive hiking areas and natural features.
A cross-country trip is a journey through history. In Washington, you can get on board for a unique dining experience at the fun Frank's Diner - Downtown Spokane. Later, as you reach the Great Lakes, come aboard for an educational and fun-filled adventure in historic Sault Ste. Marie at Soo Locks Boat Tours. The route is dotted with historical sites, local industry tours, and heritage centers that tell the story of the northern frontier.
If you are traveling with family or seeking an adrenaline rush, this route delivers. You will rock and roll on the water with the Glacier Raft Company in Montana. In North Dakota, an unforgettable, stunning experience awaits with horseback riding at Medora Riding Stables. As you reach New England, you can create a highly personalized and thrilling travel experience at Alpine Adventures in New Hampshire, and rise and shine with your family at the classic Canobie Lake Park.
We recommend a full 25 days to complete this 6,995 km journey. This allows for a manageable daily driving average, ensuring you have ample time to stop, explore amusement parks, take day tours, and truly experience the regions you are passing through rather than just viewing them from the highway.
Absolutely. Crossing the continent via the northern states and Canadian provinces offers a unique blend of untamed wilderness, Great Lakes maritime culture, and New England history. It is a bucket-list achievement for any dedicated RV traveler.
This itinerary is fantastic for families (thanks to the mix of amusement parks, aquariums, and animal shows), retirees looking for a comprehensive summer tour, and outdoor enthusiasts eager to hike, kayak, and horseback ride across diverse terrains.
Late spring through early autumn is the only practical window for this northern route. Summer offers the best weather for enjoying beaches, botanical gardens, and water activities, while early autumn provides spectacular fall foliage, particularly in the New England states.
Planning a 25-day, 6,995 km one-way trip requires careful budgeting and logistics. When securing your motorhome, keep in mind that a one-way rental from Seattle to Boston will incur a one-way drop fee, which compensates the fleet provider for repositioning the vehicle. Additionally, because of the significant distance, you will need to carefully review mileage packages—unlimited mileage or pre-purchased bulk miles are usually the most cost-effective options for a trip of this magnitude.
Your daily budget will need to account for fuel across varying regional prices (including Canadian provinces), campground fees (which range from rustic state and provincial parks to premium private RV resorts with full hookups), and attraction tickets for your family.
