How to Get a Campsite at a Sold-Out Campground

Published October 10, 2026

The campground you want is fully booked for your dates. That's normal for popular parks, and it isn't the end of the story. Here's how people actually get sites at "sold-out" campgrounds.

1. Know exactly when the booking window opens

Most popular campgrounds release dates on a rolling window. Many Recreation.gov campgrounds open about six months ahead (check the campground's page, since windows vary), and ReserveCalifornia opens six months ahead at 8 a.m. Pacific. Other state systems have their own windows, from a few months to nearly a year.

If you can, be there the minute your dates open. Create your account, save your payment details, and sign in a few minutes early. Have a shortlist of acceptable sites ready so you aren't browsing the map while others book.

2. Be flexible where it counts

  • Midweek: Sunday through Thursday nights are far easier than Friday and Saturday.
  • Shoulder season: late spring and early fall often have great weather and a fraction of the demand.
  • Any site: If you'll take any site that fits your tent or rig, you'll have many more chances.
  • Nearby campgrounds: The famous campground has neighbors, often just as good, that fill up later.

3. Watch for cancellations

This is the big one. People cancel all the time, and those sites go back on the reservation site for anyone to book. Cancellation penalties mean many people cancel just before the deadline where the cost goes up: the day before arrival on Recreation.gov, and 7 days before arrival on ReserveCalifornia.

You can refresh the reservation site yourself, but cancelled sites at busy campgrounds are often gone in minutes. A cancellation alert does the watching for you. See how campsite cancellation alerts work.

4. Piece a trip together

If you can't get the same site for every night, book what you can and fill in the rest. Moving sites mid-trip is a small hassle compared with not going. On Recreation.gov you can add nights or switch sites on a reservation without a change fee.

5. Look at first-come, first-served sites

Some campgrounds hold back sites that can't be reserved, or are entirely first-come, first-served. Arrive early on a weekday morning, when the previous night's campers are leaving.

6. Enter the lottery

Some of the most in-demand places use lotteries instead of a race. California's AB 618 required a reservation drawing for up to five of its most popular state parks, and many Recreation.gov permits work the same way.

What not to do

Don't pay someone to book a site for you, and don't buy a reservation from a reseller. Reservations generally can't be transferred, and resold bookings can be cancelled without a refund. See can a third-party website book a campsite for you?
