North Cascades National Park offers exceptional RV camping across four developed campgrounds with over 200 sites, featuring dramatic alpine peaks, over 300 glaciers, and turquoise mountain lakes in a pristine 504,000-acre wilderness. Newhalem Creek Campground provides the most accessible base inside the Ross Lake National Recreation Area, while strategic locations like Burlington RV rentals and Bellingham camper van options offer prime access to this rugged mountain paradise that welcomed just 16,485 visitors to the national park proper in 2024—making it America's second least-visited national park and a true hidden gem for those seeking solitude.
Stretching across over half a million acres of pristine wilderness, North Cascades National Park captures the raw alpine beauty and remote character of the Pacific Northwest. Famous for being the most heavily glaciated area in the continental United States outside of Alaska, it's so vast and rugged that it encompasses entire mountain ranges, deep river canyons, and pristine lakes accessible only by foot or boat. North Cascades is the ultimate RV adventure since it's home to some of the most spectacular natural wonders like turquoise Diablo Lake, the jagged Picket Range with peaks named Mount Terror and Ghost Peak, and the legendary North Cascades Highway—one of America's most scenic drives.
You'll be in store for a world of limitless adventure during your RV trip to the North Cascades, from hiking the iconic Cascade Pass Trail to boating on Ross Lake's emerald waters. You can explore over 400 miles of hiking trails ranging from easy waterfront strolls to challenging backcountry treks. There's no shortage of great spots for photography and wildlife viewing, like Thunder Creek Trail or the spectacular vistas along State Route 20. You can even access the remote community of Stehekin by ferry across Lake Chelan, where time seems to stand still. You'll want to bring your binoculars because you'll be greeted by mountain wildlife, from black bears and mountain goats to bald eagles and marmots.
The summer is the peak season for RVers and other visitors since the North Cascades Highway (State Route 20) is fully open and temperatures typically reach a pleasant 60 to 75 degrees. The late spring and early fall are a nice time of year to visit, too, with mild temperatures and spectacular alpine wildflowers. In the colder months, North Cascades National Park turns into a winter wonderland. While heavy snowfall closes the North Cascades Highway, typically from November to April, creating one of the longest seasonal road closures in America, winter enthusiasts can still access western sections for snowshoeing and cross-country skiing. No matter what time of year you take your RV road trip to the North Cascades, you'll be in for a once-in-a-lifetime adventure you'll never forget.
The park experienced remarkably low visitation during 2024, with just 16,485 visitors to the national park proper, though the adjoining Ross Lake National Recreation Area—where most campgrounds and the North Cascades Highway are located—welcomed 971,173 visitors. This unique split makes the North Cascades an ideal destination for those seeking solitude: you can enjoy excellent facilities and road access in Ross Lake NRA while having nearly unlimited backcountry wilderness to explore with minimal crowds.
You can access North Cascades primarily through State Route 20 (North Cascades Highway), which traverses the Ross Lake National Recreation Area and provides the only paved road access to the park complex. The highway is typically open from mid-April through mid-November, weather permitting. From Seattle (approximately 3 hours west), take I-5 north to Burlington, then SR-20 east through scenic mountain passes. From Spokane (approximately 5 hours east), take US-2 west to Wenatchee, then SR-97 north to SR-20 west. The highway features numerous pullouts and overlooks perfect for RVs, though winter avalanche danger necessitates the lengthy seasonal closure. Most roads inside the accessible areas are suited for RVs, with campgrounds accommodating rigs up to 50 feet. Note that very few roads actually enter the national park itself—most developed areas lie within Ross Lake NRA.
Burlington I-5 Corridor Access: Burlington RV rentals position you perfectly for the North Cascades' western access, just 60 miles from Newhalem via State Route 20. This Skagit Valley gateway offers full services, grocery stores, and fuel before you head into the mountains, making it an ideal base for stocking up on supplies for your mountain adventure.
Bellingham Northern Gateway: Bellingham camper van rentals offer excellent access to the North Cascades, approximately 90 miles northwest, while also providing opportunities to explore the San Juan Islands and nearby Mount Baker. This vibrant college town serves as a perfect jumping-off point for Pacific Northwest adventures, combining mountain access with coastal beauty.
Gorge Lake Campground offers 8 tent-only sites in a limited-development setting beside cascading Stetattle Creek. Open year-round, some sites might accommodate small RVs or trailers of 35 feet or smaller, though this is not recommended due to access constraints. During peak season (mid-May to early September), sites are $20 per night with reservations accepted; all other times they're $10 per night and first-come, first-served. Site #8 offers better accessibility features. No drinking water is available, so bring your own supply. Each site has a fire ring with a grill and a picnic table, plus year-round vault toilets.
Open from mid-May to mid-September, Newhalem Creek Campground offers 107 sites (including 13 tent-only sites and 2 ADA-accessible) plus 2 group campsites accommodating up to 25 people each. Located in the Ross Lake National Recreation Area near the town of Newhalem, this forested campground can accommodate RVs and trailers up to 50 feet long. Standard sites are $24 per night and include flush toilets, drinking water, a dump station, trash/recycling, paved roads, picnic tables, and fire rings. Group sites are $75 per night.

Surrounded by western redcedar, hemlock, and Douglas-fir, this campground provides easy access to the North Cascades Visitor Center (0.5 miles away) and town amenities.
Located closer to the park entrance, Concrete / Grandy Creek KOA serves as an excellent base for North Cascades exploration while offering modern RV amenities and family-friendly facilities.
The small communities of Marblemount, Concrete, and Rockport offer several private campground options for RVers. These campgrounds typically provide full hookups, Wi-Fi, and proximity to local restaurants and services while maintaining a mountain town atmosphere perfect for your North Cascades basecamp.
North Cascades National Park is home to over 300 species of birds that can be categorized into 38 different families. The park is also protecting two bird species that are on the “threatened” list: the spotted owl and the marbled murrelet. While you may not be able to easily spot these rare birds, you will have the chance to see many other species, including various songbirds and migrating waterfowl.
As the North Cascades Highway reopens (typically mid-to-late April), early visitors enjoy virtually empty roads with fresh mountain views. Snow-capped peaks tower above the still-closed high passes, creating dramatic contrasts. Diablo Lake's turquoise waters shine brilliantly against the remaining snow banks. This transitional period offers unique photography opportunities before summer crowds arrive.
While high mountain passes remain snow-covered, lower elevation trails become accessible in late spring. The Skagit River Loop offers an easy introduction to the park's riverside ecosystems. Ladder Creek Falls near Newhalem features illuminated nighttime displays (when operational). Thunder Creek Trail's lower sections provide accessible forest hiking through ancient trees, and the trail is suitable for those wanting a taste of the North Cascades without extreme elevation gain.
You can park your RV or vehicle at campgrounds and parking lots by the park's visitor centers and major trailheads, such as Newhalem Creek, Colonial Creek, and various pullouts along SR-20. Parking may be more limited for RVs during peak season in the summer. During busy times, popular trailheads like Cascade Pass and Thunder Knob can fill quickly, so arrive early for best parking availability.
There is no public transportation inside the park. The nearest bus services run to towns along I-5 like Burlington, Mount Vernon, and Bellingham, all over 60 miles from park entrances. Once near the park, alternate ways to get around include biking on SR-20 (with extreme caution due to narrow shoulders) and hiking on designated trails. The Lady of the Lake ferry provides passenger service from Chelan to Stehekin for accessing the southern portion of the park complex. Several private companies offer guided tours, but the remote nature of the North Cascades means your RV or vehicle is essential for exploring this vast wilderness.
Another option for reservation camping outside of the park is available at the Burlington / Anacortes KOA. This campground features over 100 sites that vary between having full hookups or being electric only. Along with having electric hookups, there are plenty of activities to enjoy within the campground, including a dog park, playground, jumping pad, kids rock climbing course, basketball and volleyball courts. Other amenities include toilets, showers, a dump station, and a dumpster.
There are also many great activities to do near the small town of Burlington. Nearby activities include whale-watching tours, scenic drives, and trekking through vast outdoor playgrounds like Diablo Lake Adventure and Deception Pass.
Campsites at Burlington/Anacortes KOA are available all year round and can accommodate rigs up to 80 feet. We recommend reserving a site before you reach the campground to ensure that you will have a place to stay.
Colonial Creek offers 38 sites in the North section and 85 sites in the South section (including tent-only options), with three ADA-accessible sites between both areas. Open from mid-May to early September, this popular campground on the shores of Diablo Lake features sites for RVs and trailers up to 25 feet for North Campground (Colonial Creek North). Sites are $24 per night, with reservations required and available 6 months to 7 days in advance through Recreation.gov. This campground provides flush toilets, water, picnic tables, fire rings, and stunning Diablo Lake access.

Reservations are required through Recreation.gov and may be made 12 months in advance.
While offering many of the same things as the others, Hozomeen Campground is different than the rest at the park due to the entrance to it being on the Canadian border. This is due to the fact that Hozomeen Campground lies on the US-Canadian Border.
Be careful when driving to the Hozomeen Campground as the roads can be pretty rough. In fact, it’s recommended that you bring a spare tire just in case. Once you arrive, you’ll find 75 designated sites to choose from, plus a few more areas that aren’t so designated. You will have to bring in your own firewood to the campground and make sure that you have enough food and water to last your trip.
Please note that all camping in this area is primitive, so the only services you’ll find are potable water and vault toilets. Hozomeen Campground is only open from May to October, so keep this in mind before heading out.
Open year-round, Goodell Creek Campground offers 19 sites (no ADA-accessible sites) in a small, intimate setting perfect for those seeking a quieter experience. The sites accommodate small RVs and trailers up to 20 feet. Sites are $20 per night during peak season (mid-May to early September) when reservations are required through Recreation.gov. The rest of the year operates first-come, first-served at $10 per night or free. Located on the banks of Goodell Creek near its confluence with the Skagit River, this campground offers vault toilets, picnic tables, and fire rings, but no hookups or potable water.
If you are willing to leave the RV behind there are many wilderness sites available for you to enjoy. These sites are much more secluded and private than the marked campgrounds and. some even have to be reached by boat. Many of these sites are fairly new, giving even more options to experience the park.
If you do plan on going wilderness camping within the park, it is vital that you take your own food, water supplies, and firewood so that you can look after yourself. It's recommended that you camp with a buddy, or, if you are camping solo, inform the park staff of where you are planning to camp and how long you will be there for.
Wilderness camping can be done throughout the year and is available on a first-come, first-served basis.
If you're up for an adventure, the North Cascades offers exceptional backcountry camping opportunities across 140 designated sites throughout the park complex. You can explore pristine wilderness accessible only by hiking or boating, including boat-in sites on Ross Lake, Diablo Lake, and Lake Chelan. Permits are required for overnight stays and must be obtained the same day or the day before your trip from the Wilderness Information Center near Marblemount. Backcountry camping in the North Cascades provides unparalleled solitude under some of the darkest skies in Washington, though proper preparation for changeable mountain weather is essential.

Late spring brings the North Cascades' wildlife out of winter dormancy. Black bears emerge from hibernation and can often be spotted foraging along SR-20 corridors. Mountain goats with new kids become visible on rocky slopes above treeline. Bald eagles patrol the rivers and lakes, while marmots sun themselves on rocks near popular trails. The quieter crowds of spring make this an excellent time for patient wildlife observers.
Summer unlocks the North Cascades' premier hiking trails. Cascade Pass Trail, a moderately strenuous 7.4-mile round-trip, showcases glacier-clad peaks and alpine meadows—often called the best day hike in the park. The Sahale Arm extension adds challenging terrain and even more spectacular views. Thunder Knob Trail provides easier access to stunning Diablo Lake overlooks. For advanced hikers, the Desolation Peak Trail follows in Jack Kerouac's footsteps to the historic fire lookout with panoramic views of Ross Lake and countless peaks.
Colonial Creek's walk-in tent sites (#64-#73) remain open all winter for the truly adventurous. With no services and potentially deep snow, winter camping here is only for experienced cold-weather campers. Goodell Creek Campground also stays open year-round. Both locations offer unparalleled solitude and dark-sky viewing, though visitors must be completely self-sufficient and prepared for severe winter conditions.
Another great way to chill out, relax and beat the cold weather is to stay in your RV for some quiet time. There is nothing more quieting and calming than North Cascades National Park in the winter time. Many visitors choose to hole up in their RV with warm blankets, comforting hot chocolate, and a good book. If you decide to stay in for the day, make sure that you are stocked up with food so you don't need to interrupt your day with a cold trip outside! Just kick back and relax in the tranquility of it all.
Winter is ideal for planning your summer North Cascades adventure. Study maps, research trails, and make campground reservation strategies for the coming season. Understanding the park's layout and seasonal patterns during quiet winter months helps you make the most of your summer visit when the park fully opens.

Winter transforms accessible areas into monochrome masterpieces. Snow-laden evergreens frame frozen waterfalls. The Skagit River flows dark against white banks. When conditions allow safe access, winter photography captures the North Cascades' harsh beauty. The low-angle winter sun creates dramatic lighting impossible in other seasons.
Winter enthusiasts can access the western sections of the North Cascades for snowshoeing and cross-country skiing. While the highway closes at milepost 134 (near Ross Dam trailhead), the section from Colonial Creek westward remains accessible. Snow-covered trails through ancient forests provide serene winter experiences. The Diablo Lake area offers stunning winter vistas, though avalanche awareness is critical—check conditions before venturing out.
Fall offers the final opportunity for high-elevation hiking before winter snows close the passes. Clear, crisp days with stable weather patterns make for excellent hiking conditions. Snow typically begins accumulating at higher elevations in October, adding drama to mountain vistas. Experienced hikers can enjoy uncrowded trails with stunning fall colors and the first dusting of snow on peaks.
September and October bring salmon returning to Cascade rivers and creeks to spawn. The fish are visible in clear streams throughout the park, attracting wildlife like black bears, eagles, and otters. Watching this ancient cycle continue provides powerful reminders of the ecosystem's interconnectedness. Various trails along the Skagit River and its tributaries offer excellent salmon viewing opportunities.
After Labor Day, visitor numbers plummet while conditions remain excellent. You can often have entire trails to yourself on weekdays. Campgrounds that required reservations all summer switch to first-come, first-served with excellent availability. The peaceful atmosphere allows for true wilderness experiences without competing for parking or campsites. This is when the North Cascades truly reveals its remote character.
Fall transforms the North Cascades into a tapestry of gold, orange, and red. Vine maples and cottonwoods along the Skagit River blaze orange and red against evergreen backdrops. Larches at high elevation turn brilliant gold in late September and early October—a phenomenon worth timing your visit around. The contrast between autumn foliage and early snow on peaks creates photographer's paradise conditions.
Summer brings ideal conditions for exploring the North Cascades' remarkable lakes. Ross Lake, stretching 23 miles north toward Canada, offers primitive boat-in camping and unmatched mountain scenery. Diablo Lake's milky turquoise color—created by glacial flour suspended in the water—makes for otherworldly paddling experiences. Both lakes have boat launches (Diablo Lake at Colonial Creek), and rentals are available at Ross Lake Resort. Kayakers and canoeists can spend days exploring hidden coves and boat-in campsites.
North Cascades' summer light creates exceptional photography conditions. Morning mist rises from Diablo and Ross Lakes, backlighting jagged peaks. Alpine wildflowers carpet meadows in July and August—especially stunning along Cascade Pass. Sunset alpenglow on glaciated peaks from viewpoints along SR-20 provides golden-hour magic. Wildlife photography opportunities abound as marmots, pikas, and mountain goats remain active throughout the day in high alpine zones.
Summer brings regularly scheduled ranger programs at the North Cascades Visitor Center in Newhalem. Evening campfire programs share stories of the park's natural and cultural history. Guided nature walks help visitors understand the complex alpine ecosystems. The park's Dark Sky designation makes it perfect for astronomy programs when offered. Check at visitor centers for current schedules, as programs vary throughout the season.
