Looking for the perfect place to park your RV this month? With so many options across America, choosing where to stay can feel overwhelming. Whether you’re a seasoned RVer or trying it out for the first time, these campgrounds are worth your attention. Once you’ve found the ideal spot, you can explore RV options, learn about different types of RVs, and plan your next road trip—maybe even fall in love with the lifestyle enough to consider full-time RV living.
I didn’t select these parks at random. With more than 25 years of experience traveling the highways and byways of the U.S. and Western Canada, I’ve learned what makes an RV campground truly exceptional. From breathtaking views and thoughtful amenities to friendly staff and spotless facilities, it’s the little things that make a big difference. These 10 campgrounds represent the very best May destinations for RV travelers.
So, sit back, relax, and start planning your next adventure. Each of these parks has been personally visited and handpicked by RVing with Rex for their outstanding experiences.

1. Portland Fairview RV Park, Portland, Oregon
This park is easy-on, easy off and on our route east on I-84 (Exit 14); also convenient for RVers continuing north on I-5 to Seattle and beyond. Although our pull-through site is just shy of 50 feet (requiring unhooking at the site) there are about 10 pull-through sites 60+ feet where unhooking is not required. 30/50-amp electric service, water, sewer, and cable TV are centrally located but some distance apart.
2. Ambassador RV Resort, Caldwell, Idaho
Ambassador RV Resort is a 5-star resort that is easy-on, easy off (I-84 at Exit 29) with 188 full-service sites, pool, spa, sauna, and 5,000 square foot recreation hall.

Pets are welcome if friendly and owner is well trained.
Located near Idaho’s wine country and convenient to the Boise metro area, the Ambassador is the perfect home base for all your activities.
3. Tom Sawyer RV Park, West Memphis, Arkansas
The endless river traffic of the Mississippi is the main attraction at Tom Sawyer RV Park and most of the sites are 100 feet or more. The atmosphere is relaxed, laid back, and peaceful. The interior roads and sites are mostly gravel. Tom Sawyer’s is located so close to the Mississippi River, sometimes the park is in it!
The Mississippi River can cause the park to close periodically anytime from December into early June but most often April or May. The Corps of Engineers and National Weather Service provides river stage forecasts which gives the park 10 to 14 days advance notice as to when the Mississippi River will force the park to temporarily shut down.
4. Barnyard RV Park, Lexington, South Carolina
Barnyard RV Park offers 129 level and grassy sites with paved interior roads. All sites include water, sewer, electric (30 and 50 amp), and cable TV. Most sites are pull-through and can accommodate large units including a tow car. Amenities include bath and laundry facilities, Wi-Fi available at site, and a dog park.
Barnyard RV Park is located 8 miles from downtown Columbia. From Interstate 20, take Exit 111 west on US-1 to the park. On weekends, experience Southern hospitality at the huge Barnyard Flea Market. The RV Park is located behind the Flea Market.
5. Dark Sky RV Park, Kanab, Utah
Dark Sky RV Park lives up to its name, a peaceful, modern retreat under some of the clearest night skies in Utah. Our site 16 offers a level, full-hookup pad with ample space to spread out and enjoy the quiet desert surroundings. The park is thoughtfully designed with wide roads for easy big-rig access, immaculate restrooms, and a stylish clubhouse that blends rustic wood and contemporary finishes.
Native landscaping—sage, yucca, and red sand—frames panoramic views of the surrounding cliffs and when night falls, the Milky Way stretches brilliantly overhead thanks to Kanab’s protected dark-sky designation. It’s the perfect balance of comfort and solitude after a day on the road.
6. Toutle River RV Resort, Castle Rock, Washington

In addition, there are a number of buddy sites.
Utilities including 20/30/50-amp electric service, water, sewer, and cable TV are centrally located. Wi-Fi works well. Interior roads are paved.

Concluding thoughts & reflections: May roads, endless possibilities
May is a month that seems made for RV travel. Spring lingers in northern forests, desert evenings remain pleasantly cool, and rivers, mountains, and small towns across the country feel newly awakened after winter’s quiet. The open road stretches ahead with the promise of discovery—whether that means watching barges drift along the Mississippi, stargazing beneath Utah’s dark skies, or waking to birdsong beside a river in the Pacific Northwest.
What these campgrounds share is more than good amenities or scenic settings. Each offers a place to pause along the journey—a comfortable base where travelers can relax after a day of exploring and feel briefly at home wherever the road has led. Sometimes the best memories come not from the miles traveled but from the simple rhythms of campground life: morning coffee beside the RV, neighbors exchanging travel stories, and the quiet satisfaction of finding just the right place to stay.
For RVers, May is an invitation. The highways are open, the landscapes are changing, and every campground holds the possibility of a new story. Wherever your travels lead this month, may the road be smooth, the campsites welcoming, and the horizon always calling you onward.
