RV Rental in Washington State, WA

Washington State has more going on for an RV trip than almost anywhere in the contiguous US. Rainforest, alpine passes, volcanic peaks, wine country, and a Pacific coastline — the geography does a lot of work. What it also does is split the state into two completely different driving environments that have almost nothing in common, and it puts a ferry system in the middle of the most popular circuit.

The class decision here is simpler than it looks: west of the Cascades, smaller vehicles access more. East of the Cascades, size doesn't matter. Get the geography right before you book the vehicle.

West of the Cascades: size determines access

The Cascade Range splits Washington into two different RV trips. West of the passes: narrow peninsula roads, a ferry system that charges by vehicle length, and campgrounds with tight site clearances. East of the passes: wide open roads, flat terrain, full-hookup RV parks, and none of those considerations.

For the Olympic Peninsula, a vehicle under 22 feet opens more than a 35-foot Class A ever will. For Spokane, the Palouse, or the Columbia River Gorge, size doesn't matter.

The Port Townsend–Coupeville ferry is where this becomes operational. It's the main crossing for the northern Olympic Peninsula, it runs smaller vessels than the main Sound routes, and oversized vehicles get held for later sailings in summer — sometimes by hours.

Inside the park, Hoh Campground's 18-mile access road has no turnaround points for large rigs. Most sites fit 21 feet; a few go longer. A campervan is easy here. A 30-footer needs site research before you leave home.

North Cascades: the constraint is the season, not the size

SR-20 itself is open to all vehicle sizes when it's open — and Colonial Creek Campground on Diablo Lake takes rigs to 35 feet. The issue is timing. SR-20 closes every winter and the spring opening date shifts year to year. In 2026, rockslide and washout damage pushed it to June 14. In a normal snow year, mid-April to early May. If your trip is April or May and the North Cascades is the anchor, plan around US-2 through Stevens Pass instead — it stays open year-round.

Seattle for the west side, Spokane for the east — choose your pickup hub before you book

There's no RV depot at Sea-Tac airport, but pickup logistics in the Seattle metro are straightforward. Cruise America runs a depot in Renton, 6 miles north of the airport — a Lyft ride away. Owner-listed inventory on both platforms is concentrated in the south Sound corridor: Renton, Kent, Auburn, Federal Way, and Tacoma, with a secondary cluster on the Eastside near Bellevue and Redmond. Most owners are 20–35 minutes from Sea-Tac in off-peak traffic, and delivery to a campground or city location is a common offering.

What most renters miss is that Spokane is a completely separate and equally good pickup market — and for any trip east of the Cascades, it's the better one. Spokane to the Palouse wine region is 90 miles. Spokane to Coeur d'Alene, Idaho is 35 miles. Spokane to Glacier National Park in Montana is 260 miles via US-2 — a straight, straightforward route through the Idaho panhandle. Picking up in Seattle and driving 280 miles to your starting point in eastern Washington before the trip begins wastes two days and several hundred mileage-cap miles.

Spokane's inventory is underused relative to how many people are actually searching for it. Both platforms have solid listings, Cruise America operates there, and nightly rates in Spokane typically run 10–15% below Seattle pricing because the market is less competitive. Options are less picked-over than Seattle during peak summer.

What a Washington rental actually costs

Seattle is a mid-to-high-cost market. Inventory is deep — both platforms have hundreds of listings in the metro area — but demand from the outdoor recreation crowd keeps nightly rates above national averages, particularly for campervans and Class B vehicles. Spokane runs cheaper across every class, usually by 10–15%. If you're comparing the platforms and wondering which has better pricing for Washington specifically, the Outdoorsy vs. RVShare comparison covers fee structures and how to run the checkout comparison — the short version is that both platforms charge similar service fees, but owner pricing variation makes running both checkouts on the same vehicle class worth the two minutes it takes.

Olympic National Park camping adds real cost to the trip budget. Hoh Campground runs $25/night in summer (no hookups). Mora Campground near the coast is $25/night. Sol Duc Hot Springs Campground is $30–35/night and books out months ahead. None of these take reservations for all sites — Hoh has a mix of reserve-ahead and first-come sites — but summer visitors who show up without a reservation before 9am are routinely turned away.

Mileage reality: Washington is bigger than the map suggests

Washington looks compact on a map. It isn't. Seattle to Port Angeles is 90 miles as the crow flies — and 3–4 hours of actual driving, because you're either circling down through Olympia or waiting for a ferry at Kingston. The Olympic Peninsula loop runs 500+ miles from Seattle and back. The North Cascades circuit through SR-20 is 380 miles before you've stopped anywhere.

The mileage math changes entirely if you fly into Spokane for an eastern Washington trip. Spokane to Walla Walla wine country is 150 miles round trip. Spokane to Coeur d'Alene is 70 miles round trip. Spokane to Sun Lakes–Dry Falls State Park is 130 miles. An eastern Washington itinerary based out of Spokane rarely exceeds 400 miles total — well inside a standard 100-mile daily cap on a 7-night rental.

Outdoorsy vs. RVShare in Washington — inventory split and what it means

Both platforms have strong Washington coverage, but the inventory skews differently. Outdoorsy has deeper campervan and Class B listings in the Seattle metro — partly because the platform skews toward newer, more frequently-rented vehicles, and campervans fit that profile better than older towables. RVShare has a wider mix of travel trailers and fifth-wheels, particularly in the south Sound and Tacoma corridor, where tow-vehicle-owning owners tend to list.

For the Olympic Peninsula specifically, both platforms have listings that offer delivery to Port Angeles or the park entrance — worth filtering for if you want to fly into Sea-Tac, take the ferry yourself as a foot passenger, and meet the RV at your starting point. Not all owners will do this, but enough do that it's a realistic option. It sidesteps the ferry surcharge entirely for longer rigs.

Spokane inventory on both platforms is underdeveloped relative to demand. Expect fewer options and less price competition than Seattle, but also lower per-night rates and owners who are used to serving eastern Washington routes. RVShare has marginally more Spokane listings; Outdoorsy's Spokane inventory has grown but remains thinner than the Seattle cluster.

Routes: Olympic Peninsula, North Cascades, and eastern Washington wine country

Olympic Peninsula loop — 3–5 days, 400–520 miles from Seattle. The classic western Washington circuit. Most renters approach via the Kingston ferry from Edmonds (shorter crossing, more frequent sailings) rather than driving around through Olympia. Port Angeles is the peninsula's hub — fuel, groceries, laundry, and the main ferry terminal to Victoria, BC. From Port Angeles, the circuit splits north to Hurricane Ridge (paved road, no RV size restrictions to the visitor center, spectacular views) and west into the Hoh Rain Forest.

The Hoh Rain Forest access road is the defining constraint of the peninsula loop. Eighteen miles of two-lane road, no commercial facilities, no turnaround points for large rigs. The campground is first-come for some sites, reserve-ahead on Recreation.gov for others — the reserve-ahead sites sell out weeks to months in advance in summer. Arriving without a reservation before 9am for a first-come site is the realistic strategy for summer visitors; arriving after noon is usually arriving to a full campground.

North Cascades circuit (SR-20 loop) — 2–3 days, 360–400 miles from Seattle. The most visually dramatic route in the state, and one of the most underrated RV circuits in the Pacific Northwest. The highway crosses two passes — Washington and Rainy — and descends into the Methow Valley, which is quieter, cheaper, and better for an RV than the Seattle side of the mountains. Colonial Creek Campground on Diablo Lake is the set-piece destination: turquoise glacial water, serious views, accepts rigs to 35 feet. Reserve on Recreation.gov several months in advance for summer dates.

The circuit completes by dropping south through Twisp and Winthrop (an Old West-themed town that's genuinely worth a stop), then looping back over US-2 through Stevens Pass. Stevens Pass stays open year-round; SR-20 does not. If you're planning a late-April or May trip and want the North Cascades circuit, check the WSDOT road conditions page before booking the vehicle. In 2026, damage kept it closed until June 14; in a normal snow year it opens mid-April to early May.

Eastern Washington wine country (Walla Walla / Yakima Valley) — 3–4 days from Spokane, 220–300 miles. This is the Washington circuit that most outdoor-focused renters overlook and most wine-country travelers haven't considered doing in an RV. Walla Walla has three full-service RV parks within 10 minutes of the tasting rooms. Yakima Valley wine country runs along I-82 with RV parks at every town. No ferry crossings, no size constraints, no mountain passes. A Class A is completely at home here. The trade-off is that the scenery is agricultural, not alpine — if the Columbia River Basin's wide-open landscape isn't your version of a beautiful drive, this circuit won't convert you.

Palouse Falls State Park is worth adding to an eastern Washington loop: one of the most dramatic waterfalls in the US, accessed via a short detour off US-12 between Walla Walla and Pullman. The campground is small but the day-use area has room for any size vehicle. Entry requires a Discover Pass — Washington State's standard parks pass, $10 for a day or $30 for the year, sold at the trailhead.
