This guide covers booking windows, cancellation alerts, first-come sites and legal backup camping. Every rule, price and window below links to the agency or company that publishes it. Prices and windows are as of September 2026. State park sites go fast. These Reserve America booking strategies improve your odds.
Why popular campgrounds show sold out
Recreation.gov lists over 103,000 reservable sites across roughly 3,600 facilities and activities, per its about page. It books them for 12 federal partner agencies. Some popular campgrounds on the site can book up in minutes, according to Recreation.gov. These figures cover Recreation.gov only. State park systems such as ReserveCalifornia take reservations on their own sites.
At Yosemite, the National Park Service says, “Reservations are extremely difficult to get: you should make a reservation as early as possible.”
The Dyrt’s 2025 Camping Report tracked the share of campers who said full campgrounds made booking a site difficult:
- 2022: 58.4%, the peak year in the release
- 2023: 45.5%
- 2024: 56.1%
- Pacific region, 2024: 66.1%
The Dyrt surveyed its own community, a representative US sample and property managers in all 50 states. Its releases do not give sample sizes. The Dyrt’s 2026 Camping Report says more than half of campers had difficulty booking because campgrounds were full, without a single figure in the release.
Know the booking window before you try
Most Recreation.gov campsites open for booking six months before your arrival date. Windows differ by facility, so check the Seasons and Fees tab on each campground’s page, per Recreation.gov. State parks set their own windows. For the basics, see how RV campsite reservations work.
Recreation.gov windows and release times
Most Recreation.gov campgrounds go on sale at 7am PT, 8am MT or 10am ET, but not all of them, per its tips for popular locations.
Yosemite runs different windows, per the NPS Yosemite campgrounds page (updated September 17, 2026):
- Upper Pines and Lower Pines open five months ahead on the 15th.
- Wawona and Hodgdon Meadow use the same window for their spring-to-fall reservation seasons.
- North Pines uses a lottery or the same five-month window.
- Some Yosemite sites open two weeks ahead.
- Tuolumne Meadows uses two windows: two months ahead on the 15th, and 14 days ahead.

Win the release morning
These steps come from Recreation.gov’s tips for popular locations and apply to its site only.
- Create a Recreation.gov account and save a preferred payment method ahead of time, so you skip card entry at checkout.
- Learn to read the availability matrix before on-sale day.
- Sync your clock to the Recreation.gov clock, which runs on Coordinated Universal Time (UTC).
- Add your site to the cart as soon as the window opens.
Recreation.gov explains the hold this way: “Once you click Add to Cart, the campsite(s) and date(s) you selected are locked in your cart for 15 minutes”. Finish checkout inside that 15-minute hold. If a spinner or a processing message appears during a high-demand on-sale, Recreation.gov’s FAQ says the system is processing your request.
Catch cancellations with alerts
A booked Recreation.gov site can become available again after the original camper’s plans change. Recreation.gov asks campers to modify or cancel reservations for trips they can no longer make. An alert tells you when that happens, but it does not hold the site for you. The alert and fee rules below are Recreation.gov’s. State systems set their own.
Recreation.gov Availability Alerts
Availability Alerts send you an email or notification when a booked campsite matching your preferences becomes available, per Recreation.gov. Recreation.gov adds, “This does not guarantee you a reservation as this alert will be sent to everyone who has alerts set for the same date”. Book fast when an alert arrives.
The Dyrt’s 2026 Camping Report says short-notice cancellations increased by 22% in 2025. The same report says no-shows decreased by 5%, and early departures of a day or more went up 27%. The Dyrt does not give sample sizes for these figures.
Campnab vs Campflare
Campnab and Campflare are third-party scanners that watch for openings and alert you. Prices below come from each company’s own page, as of September 2026. Confirm current pricing on the vendor’s site before you pay.
| Service | Cost | Alert channel | Books for you | Use case |
|---|---|---|---|---|
| Campnab | One-time scans: $10, $15 or $20, with faster scanning at higher tiers. Memberships: $10, $20 or $30 a month for 3, 5 or 7 active scans, or $90, $180 or $270 a year. | SMS | Notifies you by SMS so you can book, per Campnab | Paid SMS alerts. No free tier is listed. |
| Campflare | Free | Text or email | No, per Campflare | Free alerts. Campflare says it supports nearly all public campgrounds in the United States. |
Choose Campflare when you want free alerts by text or email. Choose Campnab when you want SMS alerts and will pay $10 to $20 for a one-time scan.
Recreation.gov cancellation and no-show fees
Recreation.gov’s reservation policies (the page is dated September 2019) set these fees:
- A $10 service fee is withheld from the refund on any cancellation.
- Cancel the day before or the day of arrival and you pay the $10 service fee and forfeit the first night’s use fee.
- A no-show costs a $20 service fee plus the first night’s recreation fee.
- A no-show site is held until checkout time on the day after the arrival date.
- Moving to dates fully outside your original dates costs a $10 change fee.
- Extending, shortening or switching to a same-price site carries no change fee.
Split stays, weekdays and nearby sites
If one site is not open for your full trip, book two or more sites back to back. Recreation.gov puts it plainly: “You may have to string together multiple campsites if the site you want is not available for your entire stay”. This works only when the availability matrix shows open nights that line up.
- Try a Sunday through Thursday trip.
- Shoulder seasons and weekday trips help you avoid crowds, per Recreation.gov.
- Look at the recommended nearby sites Recreation.gov suggests, which may have space.
First-come, first-served campgrounds
Some public campgrounds still let you claim a site in person, without a reservation. Recreation.gov says many locations that were first-come, first-served may now require advanced reservations. Seasons and rules change, so check the park or agency page for the campground before you go. Examples, as of September 2026:
- Yosemite has three first-come, first-served campgrounds in late fall, winter and early spring, not from late May through October, per the NPS.
- Olympic National Park lists Deer Park, Graves Creek, Heart O’ the Hills, North Fork, Ozette, Queets and South Beach as first-come, first-served with self-registration, per its camping page (updated August 31, 2026).
- At Olympic’s Fairholme, Hoh, Mora and Staircase campgrounds, the park says unreserved sites may be registered in person for one night only.
- New York State Parks permits walk-ins after 3 PM, subject to availability, per New York State Parks.
- Developed Bureau of Land Management (BLM) campgrounds are generally first-come, first-served, and some take Recreation.gov reservations, per the BLM.
For what is allowed inside park boundaries, see camping rules inside national parks.
Backup plan: dispersed camping and rest stops
Most BLM land allows dispersed camping unless it is posted Closed to Camping, per the BLM. Most of those areas need no permit or reservation to camp. Stays are generally limited to 14 days within any 28-day period. Regulations vary by region, so check with the local BLM field office before you go.
- After the limit, BLM says you must move to a new location, often at least 25 to 30 miles away.
- Keep vehicles on designated roads and trails unless the area is designated for off-road vehicle use.
- BLM dispersed camping is for short-term recreation, not long-term living.
- In the USDA Forest Service Intermountain Region, each forest sets its own dispersed camping stay limit, and rules may vary by forest. That region says to camp at least 200 feet from any stream or other water source. Check with the ranger district for the forest you plan to use.
New to camping without hookups? Start with boondocking for beginners and learn to find dispersed sites with Google Maps.
For a one-night stop on the road, read our interstate rest area overnight rules. Before you count on free sites, check the real costs of free RV parking.
Land access, permits, road conditions and site availability change. Verify all information with the relevant land management agency before your trip.

Your next step: open the campground’s page on Recreation.gov or the state reservation site, note its booking window and release time, and set an alert if it already shows sold out.
Frequently asked questions
When do Recreation.gov campsites become available?
Most open six months before your arrival date, and most go on sale at 7am PT, 8am MT or 10am ET, though not all do, per Recreation.gov. Check the campground’s Seasons and Fees tab for its window. Yosemite’s Upper Pines and Lower Pines open five months ahead on the 15th, per the NPS, as of September 2026. Verify the window before your on-sale date.
Do Recreation.gov availability alerts reserve the site for me?
No. An alert sends an email or notification when a booked site matching your preferences becomes available. Recreation.gov says an alert does not guarantee a reservation because everyone with an alert for that date gets it. You still need to book the site yourself as soon as the alert arrives.
Is Campflare or Campnab free?
Campflare says it is free and sends alerts by text or email. Campnab charges $10, $15 or $20 for a one-time scan, or $10 to $30 a month for memberships, as of September 2026. Campnab alerts come by SMS. Campflare says it does not book the site for you. Confirm current details at Campnab and Campflare.
What happens if I cancel a Recreation.gov campsite late or don’t show up?
Cancel the day before or the day of arrival and you pay a $10 service fee and lose the first night’s fee. A no-show costs a $20 service fee plus the first night, and the site is held until checkout time the day after arrival. These rules come from Recreation.gov’s reservation policies.
How long does a Recreation.gov cart hold a campsite?
Fifteen minutes. Once you click Add to Cart, the sites and dates you picked are locked for 15 minutes while you finish checkout, per Recreation.gov. Have your account set up and a payment method saved before the window opens so you can check out inside that hold.
Can I camp without a reservation near a sold-out campground?
Sometimes, if BLM land is nearby. Most BLM land allows dispersed camping unless posted Closed to Camping, and most of those areas need no permit or reservation, per the BLM. Stays are generally limited to 14 days in any 28-day period. In the Forest Service’s Intermountain Region, each forest sets its own stay limit. Check with the local office before you go.
