How to Use Campsite Odds to Plan Your Next Camping Trip
Campsite Odds turns each campground's Recreation.gov reservation history into a single 1–10 booking-difficulty score for every month of the year. You can start from a specific campground, a state, a national park, or just the month you want to camp — every path leads back to the same underlying odds data, scored the same way.
Key takeaways
- Every campground/month combination gets one 1–10 score, labeled Easy, Plan ahead, Hard, or Lottery-hard.
- There are four ways in: search a campground directly, browse by state, browse by national park, or check which campgrounds are easiest to book this month.
- Scores come only from real reservation history — a campground with too little data gets no page at all, rather than a guess.
- The methodology page explains exactly what feeds each score, if you want the math.
What does each score actually mean?
Every campground/month page boils down to one of four labels:
- 1–3 — Easy: usually available. You can often book close to your trip.
- 4–6 — Plan ahead: books up in the weeks before popular dates.
- 7–9 — Hard: competitive. Be ready the moment the booking window opens.
- 10 — Lottery-hard: gone within minutes of release. Bring a plan B.

How do I look up odds for a specific campground?
Type a campground's name into the search bar on the homepage, or jump straight to its page if you already know the URL pattern: /campgrounds/ followed by the campground's slug. Every campground page shows its odds across the full year at a glance, then lets you click into a specific month for that month's score, sellout speed, and lead-time chart.
Devils Garden Campground in Arches National Park is a good example of how much a score can swing across the calendar: November is Easy, while October is Lottery-hard. Scores are recalculated as new reservation data comes in, so check the live page for the current number in whichever month you're planning around.
How do I browse by state or national park?
If you don't have a specific campground in mind yet, the state index lists every state Campsite Odds covers, and a page like Utah ranks its campgrounds from easiest to hardest. Prefer to think in terms of the park itself? Pages like Arches National Park group every campground inside that park onto one page, so you can compare them side by side.
How do I find the easiest campgrounds to book this month?
The easiest-to-book pages round up campgrounds nationwide with a low score for one specific month — useful if you're flexible on location and just want a site you can actually get. Every month has its own page; see the April or September lists for examples.
A quick example: comparing two real campgrounds
1. Start with a campground you're considering — say, Devils Garden Campground in Arches National Park.
2. Open its page for the month you actually want to camp and check the label. If it reads Hard or Lottery-hard, that's your signal to either commit early or start looking at alternatives.
3. Compare it to a lesser-known option — Alum Ford Campground in Tennessee stays in the Easy range across most of the months it has data for, which makes it a realistic backup if your first choice is booked solid.
4. Bookmark the exact month page you need, and check back if your dates are flexible — a Hard month this year doesn't mean every year holds the same pattern.
Frequently asked questions
Is Campsite Odds affiliated with Recreation.gov or the National Park Service?
No. Campsite Odds is an independent almanac of booking difficulty, not run by Recreation.gov, the National Park Service, or any other federal agency. See the About page for more on how the project works.
How often are scores updated?
Scores are recomputed from each campground's aggregated reservation history as new data comes in, rather than on a fixed daily schedule. The Methodology page has the full detail on how far back that history goes and how it's weighted.
Why don't some campgrounds have a page?
Campsite Odds only publishes a score when there's enough real reservation history to trust it. A campground with too few recorded reservations, or too few months of history, gets no page for that month rather than a guess dressed up as a number.
What does "Lottery-hard" mean?
It's the top of the 1–10 scale — reserved for campgrounds where the available dates are typically gone within minutes of the booking window opening. If a month you need shows Lottery-hard, it's worth having a backup campground in mind before the window opens.
Does a low score guarantee I'll get the site I want?
No. A low score means that month has historically been easy to book, not that every date is guaranteed. Popular weekends and holidays can still book up faster than the rest of the month — worth checking the specific dates you want even at an Easy-rated campground.
