Reserving campgrounds in America's national parks
The question
How and when do we reserve campgrounds in the national parks — and what do we do if everything is full?
Two kinds of campgrounds: reserve or queue
Campgrounds inside America's national parks fall roughly into two groups: campgrounds you reserve ahead through Recreation.gov, and first-come-first-served campgrounds where you drive up without a reservation and claim a free site. Many parks have both, and some campgrounds switch systems by season.
Look this up per park before you lock in your route, because it shapes your whole plan: a reservable campground is arranged months ahead from your sofa, while a walk-up campground asks you to arrive early in the day. Both work fine with kids — as long as you know which of the two you're facing.
How Recreation.gov works
Recreation.gov is the central reservation platform for national park campgrounds and many other federal recreation sites. Create your account well in advance and explore your parks' campgrounds ahead of time, so you're not searching at the crucial moment.
Reservations open per campground in a fixed window — often months ahead, but the exact rhythm differs per park and sometimes per campground loop. Check the window for your campgrounds on the site itself and put the release moments in your calendar; relying on old forum knowledge is the classic way to miss out.
Launch days and lotteries: the busy parks
At the most popular parks, the sought-after summer sites are gone within minutes of the launch moment. Treat it like buying concert tickets: be logged in and ready, have your family size and RV length at hand, and confirm immediately — you can often fine-tune later.
A number of highly sought-after campgrounds and experiences use a lottery or an early-access window instead of first-come-first-served. That, too, is stated per campground on Recreation.gov. Miss the lottery or the launch day and all is not lost — more on that below.
Timing with kids
With children you want certainty where it matters. Reserve the nights in or right next to the busy parks as early as you can, and keep the in-between nights more flexible — there's plenty of choice there, and a private campground or a site outside the park can be just fine.
If you're aiming for a first-come campground, plan that day as a short drive day and arrive well before noon; in peak season, walk-up sites in the famous parks are often taken by mid-morning. And the shoulder seasons remain a family's best friend: less competition for sites, milder temperatures.
The pass is not a campground reservation
A common mix-up: the America the Beautiful annual pass covers park entry, not your campsite — and not the timed-entry reservation some popular parks require in peak season either. They are three separate things: pass, timed entry, campground.
So never assume 'we have the pass, so we'll get in'. How the pass itself works and when it pays off is covered in our separate guide on the national park pass (see the related guides below).
And in Canada? Parks Canada, same game
If you continue into Canada, the same pattern applies with its own system: Parks Canada runs its own reservation service, with announced launch days per park on which the season's reservations open — and there, too, the top campgrounds in Banff or Jasper go quickly on that day.
The reflexes you build for Recreation.gov — account ready, release moments in the calendar, confirm fast — carry over one to one. A full Canada plan is its own story for another time.
When the park is full
Full is rarely truly full. Just outside many parks lie campgrounds in national forests and on other federal land, plus private campgrounds and RV parks that often have exactly the amenities kids love (a pool, laundry, a playground). A site twenty minutes from the gate costs you little more than an early alarm.
Keep checking for cancellations, too: plans change and sites come back, even close to the date. And if a park really won't work, shift the route rather than the trip — which is exactly why you keep your stops in a planner instead of in concrete.
