Yes, you can camp in national parks \u2014 but most sites require a reservation through Recreation.gov, and the top campgrounds sell out within minutes of opening. This guide covers live availability for 4729 national park campgrounds, how to actually get a reservation, and what to do when everything is sold out.
Yes \u2014 almost every major US national park has at least one developed campground open to the public. The vast majority of sites are reservable through Recreation.gov 6 months in advance. A smaller number are first-come, first-served and require arriving early.
Book 6 months ahead on Recreation.gov. Most popular campgrounds sell out in minutes at opening.
Some campgrounds (Desert View, Slough Creek) take no reservations. Arrive before 7am in season.
Backcountry and some high-demand parks (RMNP timed entry) require separate permit lotteries.
You also need to pay a park entrance fee (or use an America the Beautiful pass \u2014 $80/year, covers entrance but not the campsite fee). Nightly campsite rates range from $20\u2013$35 for most developed campgrounds.
The 5-step process that actually works for high-demand campgrounds like Upper Pines and Watchman.
Go to recreation.gov and create a free account. Add a payment method in advance so you can book quickly when reservations open.
Search for your park (e.g. "Yosemite Valley campgrounds") and identify which specific campground you want — Upper Pines, Watchman, Madison, etc.
Most campgrounds release 6 months in advance at exactly 7am Pacific. For June 15, that means December 15 at 7am PT.
Be logged in at 6:58am with your campground, dates, and party size pre-filled. Submit immediately at 7:00am — competitive sites sell out in under 2 minutes.
Even if opening day sells out, cancellations happen daily. Set a free CamperWatch availability alert to get notified the moment a site opens for your dates.
Cancellation tip: Even if the opening-day rush sells out your dates, cancellations happen every single day on Recreation.gov. A free CamperWatch alert scans every 10 minutes and notifies you the moment a site opens \u2014 most alert users secure a site within 1\u20132 weeks.

California
Upper Pines, North Pines, Lower Pines in Yosemite Valley — the most-requested campgrounds in the US — release reservations 6 months in advance rolling at 7am Pacific. They sell out in under 2 minutes.
Set a phone alarm for 6:58am on the exact day 6 months before your target date. Have Recreation.gov open, logged in, and your party size pre-filled. The 3 Valley campgrounds are gone in under 2 minutes.
Hodgdon Meadow (rim of park, less demand), White Wolf (high elevation, cooler), Tamarack Flat (walk-in tent only — almost never full).
Wyoming
Yellowstone has 12 campgrounds — most are reservable through Recreation.gov, a few remain first-come first-served. Bridge Bay, Madison, Grant Village, and Canyon book out 6 months out. Slough Creek and Pebble Creek stay open longer.
Slough Creek and Pebble Creek (northeast corner) are the last to fill. They’re closer to Lamar Valley — the best wildlife-watching corridor in North America. Often available when Madison and Bridge Bay are full.
Gardiner MT (north entrance) and West Yellowstone MT have multiple private campgrounds within a 45-minute drive to main attractions.
Utah
Watchman and South Campground are the two in-park options. Watchman takes reservations; South is first-come, first-served in shoulder season. Both fill daily in peak season (March–October).
The canyon shuttle stops running after 9pm. South Campground’s first-come spots are claimed by 7am in summer. Arrive the night before, camp, and walk the Narrows before the crowds hit at 8am.
Springdale (walkable to park entrance), Coral Pink Sand Dunes State Park (45 min away), or Hurricane UT for private campgrounds.
Arizona
Mather Campground (South Rim) is the main reservable campground — 319 sites, takes reservations year-round through Recreation.gov. Desert View (East Rim) is first-come, first-served. North Rim opens May 15–Oct 15.
Desert View is 25 miles east of the main village but has the best rim views at sunrise and far fewer crowds. Show up by 7am in season for a first-come site.
Tusayan (just outside South Rim entrance), Valle AZ (25 miles south). For a different experience: Havasupai requires a lottery but is unforgettable.
Montana
Glacier has 13 campgrounds. Apgar, Fish Creek, St. Mary, and Many Glacier are reservable. Several smaller campgrounds remain first-come, first-served. Going-to-the-Sun Road access determines demand.
Many Glacier (northeastern corner) is the hidden gem — dramatic scenery, fewer people, and reservations are available longer than Apgar. A 2-hour drive from the west entrance but worth every mile.
Whitefish MT and Columbia Falls MT have private campgrounds 30–45 minutes from the west entrance.

Yes — almost every major US national park has at least one developed campground open to the public. The vast majority of sites are reservable through Recreation.gov 6 months in advance. A smaller number are first-come, first-served and require arriving early. You also need to pay both a campsite fee ($20–$35/night) and a park entrance fee unless you have an America the Beautiful pass.
The primary booking platform for US national park campgrounds is Recreation.gov. Create a free account, search your target park and campground, select your dates, and pay the nightly fee. Most high-demand campgrounds release reservations 6 months in advance on a rolling daily basis at 7am Pacific time. The most competitive campgrounds (Upper Pines in Yosemite, Watchman in Zion, Madison in Yellowstone) sell out within 2 minutes of release.
Demand for national park camping far exceeds supply, especially in summer. Parks like Yosemite Valley have fewer than 500 reservable sites for millions of annual visitors. Recreation.gov releases reservations 6 months out and they sell out within minutes for peak dates. The solution: set a CamperWatch availability alert to get notified the moment a cancellation opens a site for your dates, or arrive at a first-come, first-served campground before 7am.
Many national parks have at least some first-come, first-served sites. Notable examples include South Campground at Zion (shoulder season), Desert View at Grand Canyon (East Rim), Slough Creek and Pebble Creek at Yellowstone, Tamarack Flat at Yosemite (tent-only, walk-in), and several smaller campgrounds at Glacier. These sites are typically claimed by 7–8am in peak season.
Most reservable national park campgrounds on Recreation.gov open 6 months in advance on a rolling daily basis at 7am Pacific time. Some parks use a different system — Rocky Mountain National Park uses a timed-entry permit with a separate lottery for certain dates. Always check the individual campground page on Recreation.gov for the exact release schedule.
Three strategies work: (1) Set a free CamperWatch availability alert — campground cancellations happen every day, and the alert notifies you within minutes of a site opening for your dates. (2) Target first-come, first-served sites by arriving the evening before. (3) Book a private campground within 30–60 minutes of the park entrance as a base camp — you still get full park access without competing for the in-park sites.
The America the Beautiful pass ($80/year) covers the park entrance fee but not the campsite reservation fee. You still pay $20–$35 per night for your site through Recreation.gov. For active military and their families, the pass is free through Recreation.gov.
Free camping inside national park boundaries is extremely rare. However, many national forests and BLM lands adjacent to national parks allow dispersed camping for free with no reservation. Areas near Yosemite, Yellowstone, and other parks often have free dispersed camping within 15–30 minutes of the park entrance.
