“Sold out” is what the calendar looks like this minute. Reservations get cancelled every day, and the nights go back on sale.
What does cancelling cost?
The fees drive everything else. From Recreation.gov’s Rules and Reservation Policies:
- The reservation fee ($8 online) is not refunded.
- A $10 service fee is withheld from any cancellation refund.
- Cancel the day before or the day of arrival and you also forfeit the first night’s use fee.
- A no-show is charged a $20 service fee and forfeits the first night.
- Cabins and lookouts carry the first-night penalty from 14 days out.
Read it as a deadline, not a price list. Someone with shaky plans has every reason to wait, then decide just before the penalty lands.
How late can someone cancel?
Recreation.gov says cut-off windows are “typically between 0 to 4 days before your arrival date.” The exact one varies by campground, so check its page before you count on it.
Once a reservation date has begun, Recreation.gov says it can’t be changed online or through the call center.
When does a cancelled site go back on sale?
For campgrounds, Recreation.gov doesn’t publish a delay. In our logs, 96.7% of openings were still bookable when re-read about 94 seconds later.
Permits can differ. The Maroon Bells–Snowmass overnight permit page says “Canceled permits will be available within 24 hours of cancellation.”
So when do openings actually appear?
We logged 3,186 openings at 8 watched Colorado campgrounds, Sep 12 to Oct 1, 2026. Three patterns stood out:
- Hour: 8 AM Mountain was busiest, with 10% of openings. Midnight to 6 AM brought 3.7%.
- Day: Mondays were busiest (615), Saturdays quietest (353).
- Lead time: 54% landed within 6 days of arrival, right around the cut-off.
The charts, campground-by-campground numbers and method are on the cancellation data page.
Releases and cancellations are different things
A release is a date going on sale for the first time, on a set schedule. A cancellation is someone giving back a night they already booked, at no set time.
For a release, be ready on the exact morning; the release calendar works it out. For a cancellation, keep looking in the right week, or have something look for you.
How that watching works, free and paid: how Recreation.gov cancellation alerts actually work.
Four things people get wrong
- “Cancelling gets you a full refund.” No: the reservation fee is kept and $10 is withheld, before any first-night penalty.
- “Cut-offs are the same everywhere.” They run from 0 to 4 days, depending on the campground.
- “Once it’s booked, it’s gone.” 30% of the site-nights in our logs opened more than once.
- “Sites open up overnight.” Only 3.7% of our logged openings came between midnight and 6 AM.

Numbers. Campsite Ranger’s own logs, Sep 12 to Oct 1, 2026. They cover only the 8 campgrounds people were watching, not all of Colorado, and they don’t separate first-time releases from cancellations. An opening booked between two checks is never seen. Full method on the data page.
