Importing Recreation.gov reservations into your trip plan
How to pull your Recreation.gov campground confirmations into Milepost and build a complete trip around them, with drive times and mileage already mapped.
, 7 min read
Recreation.gov is the booking site for most national park and national forest campgrounds in the United States. If your trip touches a major national park, at least some of your nights are probably booked there. Recreation.gov handles your reservation. It does not help you plan the rest of the trip around it.
Milepost can import your Recreation.gov confirmation numbers directly. Here is how it works and what to do with the data once it is in.
What Recreation.gov covers
Recreation.gov handles reservations at most National Park Service campgrounds, many US Forest Service sites, Bureau of Land Management areas, and some state-managed sites. Glacier, Yellowstone, Yosemite, Grand Canyon, Olympic, the Smoky Mountains, Arches. If you are camping at a major national park, your reservation almost certainly goes through Recreation.gov.
Recreation.gov runs on a rolling six-month window for most campgrounds. You can book up to six months before your arrival date. For high-demand sites like Many Glacier, St Mary, or any Yosemite Valley campground (which uses a different monthly-15th release pattern), the opening day is when the campground fills. Filling typically means within minutes after 8 AM Mountain Time. The 6-month booking window guide walks through the morning-of routine.
Recreation.gov does not sequence your stops. It does not calculate drive times between campgrounds. It does not flag that your leg from campground A to campground B is 380 miles. You get a confirmation email for each booking. The trip planning work (sequencing the stops, mapping the legs, checking against the 330-mile ceiling) happens outside Recreation.gov.
Finding your confirmation number
Each Recreation.gov reservation comes with a confirmation number in the booking email. The format is a string of digits, sometimes with a dash separating two groups. If you have lost the confirmation email, log into Recreation.gov, go to “Your Trips” or “My Reservations” in the account menu, and find the confirmation number listed under each upcoming booking.
Keep these confirmation numbers somewhere accessible. If you are importing multiple stops, you will enter them one at a time.
How the import works
In Milepost, when you add a stop to a trip, there is an option to enter a Recreation.gov confirmation number. Milepost looks up the reservation and reads the campground name, address, arrival date, and number of nights from the confirmed booking. That stop appears in your trip pre-filled, with no manual data entry.
You do not retype the campground name. You do not look up coordinates. Arrival dates come from your confirmed reservation, not from a calendar field you fill by hand. If you have three Recreation.gov nights in the middle of a longer trip, you add three confirmation numbers and Milepost places each stop on the right date in the right order.
After import, Milepost calculates drive time and mileage for each leg between your confirmed stops. If any leg exceeds 330 miles or would put you arriving after 3:30 PM, Milepost marks it. You see the shape of the trip before you are committed to bookings that cannot move without a cancellation.
Building the rest of the trip around confirmed stops
Most trips mix Recreation.gov nights with other accommodation. Two Recreation.gov nights in Glacier followed by two nights at a private RV park in the Flathead Valley. A single Recreation.gov night at a Forest Service campground bookended by KOA stays on either side. The pattern is common; the planning order matters.
Add your Recreation.gov stops first. These are your anchors: dates and locations that are set. Then fill in the rest of the trip around them: private parks, KOAs, overnight stops. Base those choices on where the legs fall once your confirmed stops are placed. Stops that still need a booking carry a reservation reminder until the confirmation is attached.
Once a Recreation.gov campground is booked, that night does not move without a cancellation and a rebooking. Plan your flexible stops after you know where the anchors are, not before.
For a trip like the Glacier National Park loop, which uses Recreation.gov for all five campgrounds, importing the confirmations places every stop. What is left is checking the drive legs and adding a travel-day stop on the approach. The Glacier National Park sample itinerary on Milepost’s explore page shows the full loop with each stop placed, driving legs calculated, and every campground linked to its Recreation.gov booking page.
When your reservation changes
Recreation.gov reservations can change after you have imported them. You cancel a night, move to a different date, or get shifted to a different loop within the same campground. When this happens, the confirmation number stays the same, but the details update on Recreation.gov.
In Milepost, if a reservation changes after you have imported it, reimport the same confirmation number. Milepost refreshes the stop with the updated dates or campground data rather than creating a duplicate.
If you cancel a reservation entirely, remove that stop from your trip manually. After cancellation, the confirmation number returns a “not found” response, but Milepost does not automatically delete stops that were previously imported. The edit is yours to make.
What to do when a site is not available
The six-month window is the real constraint for high-demand parks. If you miss the opening day for Many Glacier or St Mary, the campground may show no availability for your dates.
Three approaches work:
Check for cancellations daily. People change plans. Sites open up. A Recreation.gov search run each morning in the two to three weeks before your arrival date will often surface a night or two at campgrounds that appeared full.
Look at adjacent campgrounds. If Many Glacier is full, Two Medicine, on the quieter southeast edge of the park, often has availability closer to your travel dates. It is a different experience but it is inside the park.
Consider shoulder season. Most high-demand Glacier campgrounds are fully booked in July and August. The same campgrounds often have availability in early September. Crowds drop sharply after Labor Day. The larches turn golden in the Many Glacier valley around mid-September. The trip works.
How the 330-rule applies when your campgrounds are fixed
When Recreation.gov campgrounds are booked, your arrival and departure dates at each site are set. The only variable is how you get between them.
This is where the import is most useful. Once your confirmed stops are in Milepost, the leg lengths are calculated automatically. If one leg exceeds 330 miles, you know before you are committed to the stops around it. You can add a travel-day stop between two confirmed campgrounds, break the leg into two days, and then book the intermediate stop wherever makes sense.
The 330-rule flag in Milepost applies to every leg, not just the legs between Recreation.gov campgrounds. A leg from your home to your first confirmed stop is calculated the same way. If that first leg is 500 miles, you need a stop in between before you book the campground at the far end.
Common import errors
“Confirmation not found”: Recreation.gov takes a few minutes to process new reservations. If you import immediately after booking, Recreation.gov may not have the confirmation available yet. Wait 10 minutes and try again.
Wrong campground name: Milepost reads what Recreation.gov returns. If the name looks wrong, check your original confirmation email. Some campgrounds use a different display name than the loop-level name on Recreation.gov. The data Milepost shows matches what Recreation.gov reports.
Two confirmations for the same campground: If you booked two separate blocks at the same campground because availability was split, you will have two confirmation numbers. Import both. Milepost will merge them into a single stop if the nights are consecutive at the same location.
Campground at wrong map location: A small number of Recreation.gov campgrounds have address data that does not match the physical location. If a stop lands in the wrong place on the map after import, edit the location pin directly. The reservation data is valid; only the displayed position needs correction.
What is free
The Recreation.gov import feature is part of Milepost’s free plan. You can import confirmation numbers, see drive times between your stops, and review the trip map without a paid account. The free plan covers unlimited trips and unlimited stops, so you can plan a full season of national park travel without upgrading.
Start with a trip that has one or two Recreation.gov nights. Import the confirmations, see how the legs calculate, and add flexible stops around them. The planning process is faster once the anchored stops are already placed.
Frequently asked questions
Does every national park use Recreation.gov?
Most do. A handful of smaller or state-managed sites use their own booking pages. If you are unsure, search for your campground on Recreation.gov first. If it appears there, book there. If it does not, the campground will have its own booking page.
Can I import reservations from state park booking sites?
Not through the same import flow. State parks each run their own booking sites with their own confirmation formats. For state park stays, add the stop manually in Milepost using the campground name and your confirmed arrival date.
What if I change my Recreation.gov reservation dates after importing?
Reimport the same confirmation number. Milepost will update the stop to reflect the new dates from Recreation.gov.
Do I need to import reservations to use Milepost?
No. You can add any stop manually by name, address, or map pin. The import is for convenience when you have a Recreation.gov confirmation and do not want to retype the details.
