Based on 2024 camping data, Yosemite leads with 211,216 RV stays, followed by Great Smoky Mountains (176,473 stays), Gulf Islands National Seashore (159,502 stays), and Glacier National Park (129,858 stays). These parks attract the most RV and car campers due to excellent campground infrastructure, scenic beauty, and varied RV site availability. Great Smoky Mountains remains America's most visited national park overall with 12.1 million visitors, while camping demand has surged with 56.1% of campers reporting difficulty finding available sites in 2024.
Planning a national park RV adventure? You're not alone. With over 45 million Americans planning RV trips in 2024, America's love affair with the open road continues to grow. But here's the thing—not all national parks are created equal when it comes to welcoming your rig.
We've crunched the numbers from the latest park data to show you exactly which destinations attract the most car and RV campers, so you can plan your route with confidence instead of crossing your fingers at the gate.
Yosemite National Park tops the list with 211,216 RV stays in 2024, followed by Great Smoky Mountains at 176,473 stays, Gulf Islands National Seashore at 159,502 stays, and Glacier National Park at 129,858 stays.
Here's the data-backed ranking of the top RV destinations that should be on your radar:
Despite being America's first national park with 4.7 million visitors in 2024, Yellowstone barely made the top RV destinations. This surprises many travelers, but it's likely due to the park's size, making sites feel less concentrated and some challenging road conditions for larger rigs.
For those considering full-time RV life to maximize their national park adventures, understanding the insurance implications becomes crucial. Living in your RV more than six months per year requires specialized coverage that goes beyond standard recreational policies—learn more about full-time RV insurance requirements to ensure you're properly protected on extended park tours.
These top destinations combine excellent campground infrastructure, diverse RV site options, scenic beauty, and practical amenities that cater specifically to RV travelers' needs.
The parks that attract the most RV campers share several key characteristics:
Parks near major highways and travel corridors naturally see more RV traffic. The Great Smoky Mountains, for example, sits perfectly positioned between major southeastern cities and offers easy interstate access.
The most popular RV destinations offer a mix of:
The average national park RV length restriction is 27 feet, but the most popular parks often accommodate larger rigs. Some parks allow Class A motorhomes up to 40 feet, though these longer sites are limited and book quickly.
Parks with milder climates or longer camping seasons (like Gulf Islands National Seashore) naturally attract more RV visitors who want to extend their travel windows.
Finding available campsites has become significantly more challenging, with 56.1% of campers reporting difficulty booking sites in 2024, up from just 10.6% in 2019.
The camping boom isn't slowing down. From 2019 to 2022, the number of campers who reported difficulty finding a campsite to book rose from 10.6% to 58.4%. While it dipped slightly in 2023, it bounced back to 56.1% in 2024.
The reality? Many markets are underserved, meaning camper demand exceeds available sites, sometimes dramatically. This is especially true at gateway communities near popular parks.
Most national parks restrict RVs to 27 feet on average, though some accommodate rigs up to 40 feet, while approximately 98% of campgrounds can handle RVs up to 19 feet.
Here's what you need to know about size restrictions:
Most parks have length restrictions so that you'll be able to negotiate the winding roads that lead in and out of the designated campsites. These aren't arbitrary—they're based on actual road conditions and turning radii.
Pro tip: Even if a park allows larger RVs, they may have only a few sites available. For instance, Yosemite Valley has twelve 40-foot sites—once they're booked, you're out of luck regardless of the posted limit.
Most national parks restrict generator use to daytime hours only (typically 7 AM to 10 PM) with noise limits of 60 decibels measured at 50 feet from your campsite.
Generator rules are pretty standard across national parks, but here's what you need to know:
Typically, you will not be able to run your generator between 10:00 pm and 6:00 am. Some parks extend quiet hours, so always check specific park regulations.
If it has a noise level higher than 60 decibels at a 50-foot distance, you won't be able to use no matter what the time of day. Modern inverter generators usually meet this requirement, but older models often don't.
Some campgrounds have designated "quiet zones" where generators aren't allowed at any time. These sites are perfect for tent campers and RVers who prefer natural sounds.
Many RVers are switching to:
Different RV types have varying power needs and insurance considerations. Whether you're driving a Class A motorhome or towing a travel trailer, understanding your RV insurance coverage options helps ensure you're protected during those memorable national park adventures.
Use the data above to prioritize high-capacity RV destinations, then map a route that considers seasonal weather, reservation availability, and your rig's size limitations for maximum trip success.
Here's a strategic approach to planning your park loop:
Focus your route around the parks with the most RV stays—they have the infrastructure and experience to handle your needs. Use our top 5 list as anchor points for your trip.
KOA's research found that one-third of new campers in 2022 were millennials, and they're booking earlier. Summer dates fill fastest, while shoulder seasons offer better availability and weather.
With camping demand outpacing supply, always have alternatives ready. Research nearby state parks, private campgrounds, and RV-friendly businesses for overflow situations.
