If you want to camp in a national park, national forest, or other federal recreation area, you will almost certainly use Recreation.gov. It is the official reservation site for campgrounds, cabins, permits, and tours managed by federal agencies, including the National Park Service, USDA Forest Service, Bureau of Land Management, and U.S. Army Corps of Engineers.
Popular campgrounds can sell out within minutes of opening. This step-by-step guide explains how booking windows work, how to prepare, and what to do if your dream site is already gone.
Step 1: Create and Prepare Your Account
Do this days before you plan to book, not on release morning.
- Create a free account and confirm your email address.
- Add your name, phone number, and address to your profile.
- Save a payment method or keep your card nearby.
- Download the Recreation.gov app if you prefer booking by phone, and sign in ahead of time.
Step 2: Find the Right Campground
Search by park, forest, town, or campground name. On the results map, filter by dates, number of people, equipment (tent, RV length, trailer), and amenities such as electric hookups or accessible sites.
Open each campground page and read it carefully. Key sections include:
- Overview and Need to Know: Rules about pets, fires, food storage, generators, check-in times, and cell coverage.
- Seasons and booking information: When the campground is open and when reservations become available. Recreation.gov's FAQ notes that booking windows are set by each individual facility.
- Campsite list and map: Each site's size, maximum vehicle length, number of people allowed, and whether it is tent-only or RV-friendly.
Step 3: Understand Booking Windows
This is the part that confuses most first-time campers. There are a few common systems.
Rolling Windows
Many campgrounds let you reserve a set amount of time ahead, often six months. Each day, one more day becomes available. For example, with a six-month rolling window, on November 10 you could book dates through around May 10. Yellowstone describes its campgrounds this way: you can book a site six months before the date of your stay.
Monthly Block Releases
Some very popular parks release an entire month of dates at once. Yosemite, for instance, releases most campground reservations in monthly blocks several months in advance. Acadia's Blackwoods Campground releases most sites six months ahead on the first of each month at 10 a.m. Eastern, with a smaller share released 14 days before arrival.
Short-Window and Same-Day Sites
Some campgrounds hold back a portion of sites for shorter windows, such as two weeks ahead. Others offer same-day booking if sites are still open. A few remain first-come, first-served for part or all of the year.
Lotteries
For a small number of high-demand campgrounds and many permits, Recreation.gov uses lotteries. You apply during a set window, and winners get a time to book.
Step 4: Know the Release Time
According to Recreation.gov's tips for popular locations, most campgrounds go on sale at 7 a.m. Pacific, 8 a.m. Mountain, or 10 a.m. Eastern, but not always. Confirm the exact date and time on the campground page, and pay attention to the time zone.
Step 5: Booking Day Game Plan
- Log in early. Be signed in at least 10–15 minutes before release.
- Have a shortlist. Pick three to five acceptable sites and at least one backup campground.
- Sync your clock. Recreation.gov suggests synchronizing with its clock so you refresh at exactly the right moment.
- Use one window. Recreation.gov advises against logging into multiple browsers or tabs with the same account, which can trigger extra reCAPTCHA checks and slow you down.
- Refresh on time. At release time, refresh the page, select your arrival date and departure date, and click Add to Cart.
- Check out quickly. Once a site is in your cart, it is held for 15 minutes. Fill in the required details, agree to the "Need to Know" information, and pay.
Step 6: After You Book
- Save your confirmation. Download or print it. Cell service at many campgrounds is weak or missing.
- Read the arrival details. Check-in times, gate codes, and parking limits are usually listed in your reservation.
- Remember entrance fees. A campsite reservation usually does not include park entrance fees. An America the Beautiful pass covers entrance fees at most federal recreation sites; in 2026 it costs $80 for U.S. residents and $250 for nonresidents.
- Watch for alerts. Check the park or forest website before you leave for closures, fire restrictions, or road issues.
Changes, Cancellations, and No-Shows
Plans change, and that is normal. Under Recreation.gov's rules and reservation policies:
- Reservation, change, and cancellation service fees are generally non-refundable.
- A service fee is withheld from refunds when you cancel, and late cancellations can cost more, sometimes including the first night.
- If you do not arrive and do not cancel by check-out time on the day after your arrival date, you are considered a no-show and the site can be released.
- Individual locations can have their own policies, which override site-wide rules. Always read the specific campground's policy.
If you cannot use your reservation, cancel it as early as possible. Someone else is probably watching for that exact site.
What If Everything Is Sold Out?
Sold-out does not always mean impossible. Try these strategies:
- Check back often. Cancellations happen constantly, especially in the week before arrival.
- Be flexible with dates. Sunday through Thursday nights are far easier to book than weekends.
- Split your stay. Recreation.gov notes you may need to combine multiple sites if one site is not available for your entire trip.
- Look nearby. National forest and Army Corps of Engineers campgrounds near popular national parks often have more availability.
- Consider first-come, first-served sites. Arrive early on a weekday morning for the best chance.
- Try dispersed camping. Many national forests and BLM lands allow free camping outside developed campgrounds. See our beginner's guide to dispersed camping.
- Call for help. The Recreation.gov call center is available at 1-877-444-6777 if you run into problems online.
Common Mistakes to Avoid
- Booking a site that is too short for your RV or trailer. Check the maximum vehicle length.
- Exceeding the site's limits on people, tents, or vehicles.
- Assuming every campground has water or showers.
- Forgetting time zones when setting your alarm for release day.
- Not reading the "Need to Know" section about fires, food storage, and quiet hours.
Frequently Asked Questions
How far in advance can I book on Recreation.gov?
It depends on the campground. Many use a six-month rolling window, some release monthly blocks, and some offer shorter windows. The campground page lists the exact booking window.
What time do Recreation.gov campsites open for booking?
Many release at 10 a.m. Eastern (7 a.m. Pacific), but times vary. Always confirm on the campground page.
How long is a campsite held in my cart?
Fifteen minutes. If you do not complete the purchase in that time, the site is released for others.
Can I book state park campsites on Recreation.gov?
Generally no. Recreation.gov covers federal sites. State parks use their own reservation systems, which you can find on each state's park website.
Does my reservation include the park entrance fee?
Usually not. Plan to pay the entrance fee separately or use an annual pass.
Book Smarter, Camp More
Booking a campsite at a popular park is part research and part timing. Learn the booking window, prepare your account in advance, log in early, and keep backup options ready. With a little planning, you will spend less time refreshing and more time around the campfire.
