Reservations for Dillion are made through Recreation.gov. In peak season, the most popular campgrounds are typically claimed within minutes of each release — which is why the park reads as "sold out" for most of the year.
Sold out is not final, though. People book far ahead and plans change, so cancellations return to the official calendar throughout the season — with no announcement, at any hour. A cancelled site is bookable by whoever sees it first.

We scan the official Recreation.gov calendar for Dillion around the clock. The second a site that matches your dates and equipment opens up, you get a text with a direct link to that exact site. You book it yourself, in your own account, at the normal price. We never book, hold, or resell anything — monitoring is all we do, and it's what your fee pays for. Openings are first-come, so a text beats an email every time.
