When do Piñon Flats reservations open?

Individual and group sites can be reserved on recreation.gov up to 3 months ahead, per the park. That's shorter than the six months many campgrounds use, so summer dates open later than you might expect. Group sites must be booked at least four days ahead.

The park lists Piñon Flats as open April 1 to October 31, by reservation only. For first-come camping, the park points to the 21 primitive sites on Medano Pass Primitive Road.

Rules verified Oct 29, 2026 against the Piñon Flats page and the Great Sand Dunes camping page. Rules change: check before you book.

Where these numbers come from

Our census checks the campgrounds we cover on recreation.gov on a regular schedule and logs each time a site-night switches to available. These counts cover Oct 1–29, 2026. A site someone cancelled and someone else booked before our next check isn’t counted, so the real number is higher. The census can’t tell a cancellation from a site released for the first time. Sites recreation.gov marks as first-come (“Open”) aren’t counted. More in our cancellation data.
