RV Travel
The National Parks RV Guide
An RV turns several national parks into one trip — you sleep at the trailhead and wake up inside the park. Two decisions matter more than the rest: the size rig you pick, and how early you lock in the reservations.
Pick the rig
Choose the right size RV — usually smaller than you think
The rule that saves the most trips: take the smallest rig you'll be comfortable living in. Bigger means more to drive on mountain switchbacks and more campgrounds that won't take you. If you've never driven one, rent for a weekend before you commit to a two-week trip.
- Class B (camper van): a mini kitchen and a pop-up bed. Best for couples, easiest to drive and park, fits almost anywhere.
- Class C (around 25 feet): the family-of-four pick. Fits most national-park campgrounds and is manageable on hilly park roads.
- Class A (30+ feet): the most home-like, the hardest to drive (it's a bus chassis), and the one that gets turned away — many in-park campgrounds cap rigs under 30 feet, and some park roads restrict it.
Book the rig
Where to rent
Two national options cover most trips: Cruise America (the big rental chain, depots nationwide) and Outdoorsy (peer-to-peer — the Airbnb of RV rentals, where you rent an owner's rig). On the West Coast, smaller outfits like Jucy and Roamamerica rent camper vans out of the major fly-in cities.
Know the limits
Where RVs are restricted — check before you go
Most parks welcome RVs: the main lots have RV-sized spaces, the roads are wide, and other drivers are used to slow rigs. But some parks restrict them, and you want to know which before you're at the gate. Zion's Mt. Carmel Tunnel requires an RV permit for larger rigs. And many in-park campgrounds enforce a length limit — commonly under 30 feet — that rules out a Class A. Look up your park's size limits and tunnel or road restrictions before you book the rig, not after.
- Zion: the Mt. Carmel Tunnel needs an RV permit (and traffic control) for oversized rigs — budget time for it.
- Campground length limits: check the per-campground maximum; in-park sites are often shorter than commercial parks.
- Mountain roads: a few high or narrow park roads restrict large RVs outright — verify on the park's NPS page.
Reserve early
Book the campsite the moment it opens
In-park RV sites are the bottleneck. On a popular weekend, spots fill by midday, and the premium ones go within minutes of release. The fix is knowing your park's release window and being on Recreation.gov when it opens. Yosemite, for example, releases campsites four months ahead, at 7 a.m. Pacific on the 15th of the month. Set the alarm; don't wing it.
- Find your park's reservation-release window on Recreation.gov and mark it.
- Be logged in and ready at the release time — prime sites disappear in minutes.
- Reservations change seasonally; confirm the current window before you plan around last year's.
Plan B
When the park is full, camp just outside
In-park sites sell out, so have a fallback. KOA runs roughly 500 campgrounds near and along the routes to the parks, most with full hookups. Harvest Hosts gets you free overnight parking at farms and wineries. Resort chains like Encore and Thousand Trails fill the gap when the park itself is booked — you trade the in-park location for availability and amenities.
Don't just drive
Get out of the RV
The point of the trip is the park, not the rig. Park it and use the free shuttles where they run (Zion's is the obvious one), bring bikes on a rack, or tow a small car for the narrow back roads and the town runs. Long-haul RVers say the same thing: the easier access is being able to park in so many more places — once you're out of the driver's seat.
Plan the trip
Map your route
An RV's whole advantage is stringing parks together. See the cross-country loop for the order to drive them, and the field-tested guides for the day-by-day inside each park — where to stay, which hikes to prioritize, and the contingency plan when a road or trailhead is full.
One pass, every park
One pass covers entry to every park you'll visit.
The America the Beautiful annual pass covers the entrance fee at every national park. On an RV trip that strings several together, it pays for itself within the first few stops.
