The Pacific Northwest is the kind of place that changes how you think about RV travel. Towering old-growth forest, active volcanoes, wild coastline, high desert — all of it within a few hundred miles of each other. A well-planned PNW loop can cover some of the most varied terrain in North America, and it rewards rigs of every size, from compact Class B vans to 40-foot diesel pushers.

This guide covers a route that works. It runs roughly 1,400 miles and takes three to four weeks to do properly. Rushing it misses the point.

When to Go

June through September is the window. The PNW has a reputation for rain, and that reputation is earned. But summers here are genuinely spectacular. July and August bring clear skies, warm temperatures in the 70s and 80s and long daylight hours that stretch past 9 PM. June is cooler and less crowded. September is arguably the best month: the crowds thin after Labor Day, temperatures stay comfortable and the fall colors start showing up in the Cascades.

Avoid May if you can. Crater Lake's Rim Drive often stays closed until late May or even June due to snow. Olympic National Park's Hurricane Ridge Road has similar issues. You don't want to build an itinerary around roads that might not be open.

October through April means unpredictable mountain passes, closed facilities and many campgrounds operating on skeleton schedules or shut entirely. Some dispersed camping roads in the national forests become impassable mud. Not worth it unless you're specifically chasing an off-season experience with a capable rig.

The Route Overview

Starting in Portland gives you a convenient hub with good fuel prices, propane availability and easy RV supply access before you head out. From there, the route runs:

Portland → Columbia River Gorge → Mount Rainier → Olympic National Park → Oregon Coast → Crater Lake → back to Portland

Total distance: roughly 1,400 miles with side trips factored in. Figure on 14 to 21 driving days depending on how long you linger. And you will linger.

If you are still deciding whether this route fits your rig, start with MyRVSelector's guide to choosing the right RV size before you lock in campground reservations. Smaller rigs open up more national park options, while larger RVs usually need more private-park backup plans.

Stop 1: Columbia River Gorge

Less than an hour east of Portland, the Gorge hits you fast. The Columbia cuts through the Cascades in a canyon that averages about 4,000 feet deep, with waterfalls dropping off the Oregon side every few miles along the Historic Columbia River Highway. Multnomah Falls alone, at 620 feet, is worth the stop.

Campground picks:

• Cascade Locks Marine Park (Cascade Locks, OR): Pull-through sites for rigs up to 40 feet. Right on the river. Showers, hookups and within walking distance of the downtown strip. Book early in summer.
• Viento State Park (Hood River, OR): Smaller sites, best for rigs under 30 feet. No hookups but a great base for windsurfing and hiking day trips. The Columbia views from here are hard to beat.
• Maryhill State Park (Goldendale, WA): On the Washington side, this one is often overlooked. Full hookups, big pull-throughs that handle 45-foot rigs comfortably and far less competition for sites than the Oregon campgrounds.

The Gorge is also your first taste of driving consideration. US-30 (the Historic Highway) has low-clearance tunnels. The lowest is 14 feet 8 inches at Crown Point. If you're in a tall rig, stick to I-84 and access viewpoints from the frontage roads and day-use areas.

Stop 2: Mount Rainier National Park

Head north into Washington. Mount Rainier stands at 14,411 feet and is visible from Seattle on clear days, which is not every day. Getting close to it is a different experience. The mountain is enormous in a way photographs don't capture, and the subalpine meadows around Paradise and Sunrise are genuinely otherworldly in July and August when the wildflowers peak.

Campground picks:

• Cougar Rock Campground (southwest side, NPS): 173 sites, up to 35 feet for RVs. There are no electrical, water or grey-water hookups in Mount Rainier's park campgrounds, so arrive ready to dry camp. Reservations through Recreation.gov go fast. Book 6 months out if you want a summer weekend. This is the main campground for the Paradise area.
• White River Campground (northeast side, NPS): First-come, first-served during its normal summer season, with smaller RV and trailer limits than Cougar Rock. This is a better fit for compact rigs and travelers aiming for the Sunrise side of the park.
• La Wis Wis Campground (Gifford Pinchot National Forest): Just outside the park boundary on US-12. Handles rigs up to 32 feet, no hookups, but it's a solid fallback when the NPS campgrounds are full. First-come, first-served in early and late season.

For 2026, do not build your plan around Ohanapecosh Campground. The campground and surrounding developed area are closed for rehabilitation work through the 2026 camping season.

One heads-up for big rigs: the road to Sunrise (the north side of the park) has steep grades and tight switchbacks. Class A motorhomes over 35 feet or fifth wheels with long wheelbases should check with the park before attempting it. The Sunrise road is fantastic, but not worth a scrape-up or a difficult turnabout situation.

Dispersed camping option: The Gifford Pinchot National Forest surrounds the south and west sides of Rainier. Dispersed camping is free with no permit required (14-day limit). Forest roads off US-12 and SR-123 access some excellent spots. You'll need a self-contained rig and a good topo map or AllTrails download.

Stop 3: Olympic National Park

Olympic is one of the most ecologically diverse parks in the country. You've got temperate rainforest in the Hoh Valley, alpine terrain around Hurricane Ridge, 73 miles of wild coastline and rivers full of salmon. The park covers most of the Olympic Peninsula, and you can drive its perimeter loop (US-101) in a day, though that would be a waste.

Plan at least 4 to 5 nights here. Three nights is the minimum to see the rainforest, the ridge and the coast without feeling rushed.

Campground picks:

• Kalaloch Campground (Kalaloch, WA): 170 sites right on the Pacific coast bluff. Some sites have direct ocean views. Max RV length is 35 feet, though a few larger sites exist. Reservations required from late May through September. This is one of the most sought-after campgrounds in Washington state.
• Hoh Rainforest Campground (Hoh Rain Forest, WA): 88 sites, max 21 feet recommended (longer rigs have navigated it, but the road in is tight). Worth it for waking up in old-growth Sitka spruce. No hookups. Reservations open on Recreation.gov and they vanish.
• Heart O' the Hills Campground (Port Angeles, WA): 105 sites, up to 35 feet. Gateway to Hurricane Ridge. Lower elevation than the ridge itself, so a good base for day trips up to the alpine zone.
• Sequim Bay State Park (just east of the park): Full hookups, sites up to 60 feet. Sequim sits in a rain shadow and gets only about 16 inches of rain a year. Good staging point for Olympic day trips with a large rig.

Dispersed camping: Olympic National Forest (separate from the national park) has dispersed areas along the Quinault, Quilcene and Dosewallips drainages. These are generally accessible to rigs under 25 feet. The Quinault Valley in particular has some beautiful primitive sites along forest roads south of the park boundary.

Hurricane Ridge Road: at 5,242 feet elevation, it can close without warning in any month due to weather. Check road status at the park's website the morning you plan to go up.

Stop 4: Oregon Coast

Coming south from Olympic, drop back into Oregon via US-101. The Oregon Coast is 363 miles of publicly accessible shoreline. Unlike much of the California coast, nearly all of Oregon's beaches are state-owned and open. The highway hugs the water for most of its length, which makes for slow but spectacular driving.

Pick two or three spots rather than trying to camp every night. The coast has enough state parks with RV camping that you could stay on the water the entire way.

Campground picks:

• Fort Stevens State Park (Hammond, OR): One of the largest campgrounds in the Oregon state park system. Over 500 sites, full hookups available, pull-throughs that handle 60-foot rigs. Near the mouth of the Columbia. Can feel like a small city in peak summer, but the facilities and location are hard to argue with.
• Beverly Beach State Park (Newport, OR): 279 sites, hookups available, max 65 feet. Just north of Newport, which has excellent seafood and the Hatfield Marine Science Center. The beach access trail runs through a tunnel under US-101.
• Sunset Bay State Park (Coos Bay, OR): Quieter than the northern coast campgrounds. 138 sites, hookups available, 50-foot max. The bay here is sheltered and warm enough to swim, which is rare on the Oregon coast. Cape Arago and Shore Acres State Park are both within a few miles.
• Cape Blanco State Park (Port Orford, OR): The westernmost point in Oregon. Windy, dramatic and far less crowded than campgrounds further north. Full hookups, pull-throughs, 65-foot max. The lighthouse is the oldest in Oregon.

Rig note for the coast: US-101 through the Oregon coast has several stretches with posted RV length restrictions and a few bridges with weight limits. These are posted clearly, but do your research before heading down the Three Capes Scenic Route or any of the side loops. Some are genuinely not suitable for large fifth wheels or Class A motorhomes.

Stop 5: Crater Lake National Park

Crater Lake closes the loop back toward Portland. At 1,943 feet deep, it's the deepest lake in the United States and the bluest water you've likely ever seen. The caldera formed roughly 7,700 years ago when Mount Mazama erupted and collapsed, and the lake has been filling ever since, with no rivers in or out.

Rim Drive circles the caldera at 33 miles. Drive it. Stop at every overlook. It takes most of a day and it's worth every minute.

Campground picks:

• Mazama Village Campground (inside the park): 214 sites, up to 50 feet in designated sites. This is the only developed Crater Lake campground where RVs and trailers belong, and reservations fill up fast. Elevation is about 6,000 feet, so nights get cold even in July.
• Diamond Lake Campground (Umpqua National Forest): About 12 miles north of the park. 238 sites, hookups available, handles larger rigs well. Diamond Lake itself is beautiful with good fishing and kayaking. This is the best fallback when Mazama is full.

Lost Creek Campground is not an RV option. The park's rules designate it for tent camping only, with RVs directed to Mazama Campground.

Dispersed camping: The Umpqua and Winema-Fremont National Forests bracket Crater Lake on the north and south sides. Both have extensive dispersed camping opportunities accessible to rigs under 30 feet. The North Umpqua River corridor in particular has some excellent primitive sites along Forest Road 37 and its branches. Free, no permit, 14-day limit.

Practical Notes for the Full Loop

Fuel: Gas prices in rural Oregon and Washington can spike. Fill up in larger towns like Portland, Bend, Eugene, Port Angeles and Olympia. Don't count on finding competitive prices on the Olympic Peninsula or near Crater Lake.

Reservations vs. first-come: The NPS campgrounds in this region book out within minutes of the Recreation.gov reservation window opening (typically 6 months in advance for summer dates). If you miss the window, build in flexibility for first-come alternatives or lean on the national forest fallbacks mentioned above. Many state park campgrounds use the Oregon State Parks or Washington State Parks reservation systems, separate from Recreation.gov.

For a deeper booking framework, use MyRVSelector's guide to finding the best RV parks and campgrounds before you start reserving sites.

Dump stations: Not every campground has them, especially in the national forests. Know where the nearest dump station is before you run out of capacity. Sanidumps.com is the most reliable directory.

Cell service: Expect dead zones throughout this route. Olympic National Park's interior has almost no coverage. Crater Lake is spotty. The Oregon coast has gaps between towns. Download offline maps before you leave Portland and don't rely on streaming for entertainment in the backcountry.

Propane: Top off before entering any national park. Crater Lake's nearest propane fill is in Prospect or Diamond Lake Junction. On the Olympic Peninsula, Port Angeles and Sequim are your best bets.

Road conditions: Mountain passes on this route (US-12 over White Pass, OR-138 to Crater Lake) can have construction delays in summer. Check WSDOT and TripCheck.org the morning of any mountain driving day.

Making It Your Own

This route is a framework, not a rigid plan. Some people add a side trip to Leavenworth or North Cascades from the Rainier leg. Others skip the southern Oregon coast and cut inland to Bend for hiking and craft beer. A few ambitious travelers extend the loop south to Redwood National Park in Northern California.

The Pacific Northwest rewards patience. The best version of this trip is the one where you have nowhere specific to be tomorrow morning. Build in buffer days. Stay an extra night when a campground surprises you. Drive less, hike more.

The road will be there when you're ready to move on.

If this trip has you rethinking your setup, compare RV sizes, layouts and dealer options before your route gets more ambitious. A local dealer can help you match the right RV to the places you actually want to camp.
