RV Campground Finder and Length Checker
Find federal campgrounds by state from official National Park Service and Recreation.gov data, and filter park campgrounds by your rig length.
Pick a state and enter your total rig length. The finder lists National Park Service campgrounds that publish an RV length limit your rig fits, plus national forest, BLM, Army Corps of Engineers and other federal campgrounds from the Recreation Information Database. Free, private, and every result links to the official page.
Data: National Park Service API and the Recreation Information Database (Recreation.gov), refreshed October 2, 2026. Agencies change length limits, seasons and closures; confirm with the campground before you travel. Freedom Road Living is not affiliated with either agency.
How the RV campground finder works
This tool reads two official government sources. First, the National Park Service API lists every campground in the national park system, including the maximum RV and trailer lengths that many parks publish. Second, the Recreation Information Database (RIDB) is the federal dataset behind Recreation.gov. It covers campgrounds run by the USDA Forest Service, the Bureau of Land Management, the U.S. Army Corps of Engineers, the Bureau of Reclamation and other agencies.
When you enter a length, the finder hides park campgrounds whose posted limit is shorter than your rig. Campgrounds that do not publish a limit stay in the list with a “call ahead” note, because no limit listed does not mean any length fits. For national forest, BLM and Army Corps campgrounds, site lengths vary site by site, so open the Recreation.gov page and check the individual site details before you book.
How to measure your total rig length
Length limits almost always mean the whole unit that has to fit on the site. For a motorhome, measure from the front bumper to the rear bumper, including ladders, bike racks and spare-tire carriers. If you tow a car, many campgrounds want the car parked alongside rather than behind, so check both numbers. For a travel trailer or fifth wheel, measure the trailer from the hitch coupler to the rear bumper, and note the tow vehicle length separately.
- Use the measured number, not the brochure. Model names such as “26” rarely match the true overall length.
- Add slide-outs to your width planning. Tight wooded sites can block slides even when the length fits.
- Round up. If you measure 31 feet 4 inches, search for 32 feet.
Why national park length limits matter
Many national park campgrounds were laid out decades ago for smaller vehicles. As a result, loops can have tight turns, short pull-through sites and low-hanging branches. A posted length limit is the park’s way of saying which rigs can safely reach and use a site. Arriving with a longer rig can mean being turned away at the gate, even with a reservation. Therefore, check the limit before you book, then read the campground’s own page for site-by-site details.
For a state-by-state table of every national park campground that publishes an RV or trailer limit, see our guide to national park RV length limits.
Where the data can be wrong
Agencies update their data on their own schedules. Campgrounds close for construction, fire, flooding or the season, and limits can change after road work. We refresh the data weekly and show the refresh date under the results, but the managing agency is always the final word. Call the campground or check its official page before you travel, especially for long rigs and first-come, first-served sites.
When this tool helps most
Use it when you plan a route through federal lands. It searches official campground records by state and rig length, then links you to each official page to confirm details and book.
Common mistakes to avoid
- Treating a length listing as a guarantee without reading the official page.
- Forgetting that some loops and sites are shorter than the campground maximum.
- Booking without checking seasonal opening dates.

Frequently asked questions
Yes. It is free, it does not require an account, and we do not store the state or length you enter. No. It covers federal public-land campgrounds only: national parks, national forests, BLM land, Army Corps of Engineers lakes and other federal areas listed in RIDB. Private parks and most state parks are not included. Many campgrounds do not publish a single maximum length because site lengths vary. When no limit is listed, check the individual site details on Recreation.gov or call the campground. No. Each result links to the official National Park Service or Recreation.gov page, where you can check availability and reserve directly with the agency.Is this campground finder free?
