Visiting our country’s national parks is a bucket list item for an enormous number of people out there. Of course, the best way to do this is in an RV, but it is important to be aware of national park RV length limits.

Things to Consider When Booking National Park Campsites
When it comes to booking a site in a state or national park, there are several factors to consider that will determine what kind of rig you bring. Unfortunately, as is the case with national parks’ RV length limit rules, these factors can differ from one park to the next, meaning you’ll have to do a bit of research before you set out in order to ensure your RV is not only the appropriate length for the site, but also fits into other guidelines set by the park.
Rules to check for include the following:
Combined Length
In some cases, a state or national park RV size limit is a combined limit. This means the trailer and tow vehicle must both fit into the length limit. Driving a motorhome? Your tow car must also fit into those RV length limits when hitched up.
We’ve noted which parks have set a combined length limit in the RV length restriction by state list above.
Slides
There are a few state and national park campgrounds that are on the narrower side. Since your slides must always stay within your own site, it’s a good idea to confirm that the width of your RV with slides extended will fit into a site before booking it.
Acadia National Park specifically mentions that slides must fit into the RV space.
Limited Long Sites
We’ve answered the question, “What is the maximum length of RV allowed in national parks?” However, while there are some state and national parks that can accommodate longer rigs, these bigger campsites are often very limited. This is especially true in national parks campgrounds.
Because of this, if you plan to visit a state or national park campground and require a longer site, we highly recommend reserving your site as far in advance as possible and avoiding first-come, first-served campgrounds entirely.
Arches and Yosemite are two examples of national parks with very limited longer RV sites.
Road Length Limits
It’s also important to note that some roads in some parks will have vehicle length limits. This means that what size RV is allowed in national parks will vary based on where you wish to go.
A good example of this is Sequoia National Park. Here, RVs up to 42 feet in length can stay at the Lodgepole Campground, but many roads don’t allow vehicles longer than 22 feet in length. Obviously, it is possible to get to the campground without driving on roads with lower length limits, but you will want to leave your RV in the campground for the duration of your stay, exploring with a car or truck instead of the whole rig.
Motorhomes Only
In some campgrounds, motorhomes are allowed, but trailers of any size are prohibited. Gold Bluffs in Redwoods National Park is an example of this.
Other times, the limit for motorhome length might be different from the limit for trailer length. For instance, Yosemite National Park allows motorhomes up to 40 feet long, while trailers can only be as long as 35 feet.
Long Site Upcharge
In some instances, you’ll find that while long sites are available, there is an upcharge to use them. Some find that this upcharge is money well spent as it means they can take their larger, more comfortable motorhome or trailer into the park. That said, if you wish to avoid extra site fees, sticking to a smaller rig is your best bet.
Some of the national parks that charge an extra few bucks for longer sites include Arches and Denali.
Seeing National Parks and State Parks in a Large RV
Want to go longer but still see the national parks? No worries! Go ahead and get your larger motorhome or trailer. In some cases, you’ll still be able to camp in the national and state parks you choose to visit. When you can’t, simply plan to camp just outside the park.
In many cases, free boondocking with no RV length limits is available on the land surrounding national parks, and privately owned campgrounds are almost always available near natural attractions such as state and national parks. As long as you stay as close to the park as possible, you will likely still get the same amazing views from the window of your RV, meaning you won’t be missing too much by making such a compromise.
