Findings from continuous watching

Where openings vanish fastest, measured

A cancelled site doesn't stay open for long. We measure how long we saw it: the median time between our check spotting an opening and our next check seeing it gone, at each campground we watch closely enough to trust the number. A date leaving the grid is not proof anyone booked it — a hold, a block or a season change removes it too — so this is how quickly openings were gone after we spotted them, not a rebooking time. Only detections made on a fast census cadence count — a slow check could miss an opening that vanished within the minute, so those are excluded rather than allowed to skew the number.

Still measuring how quickly openings are gone after we spot them at the campgrounds we watch. Check back as more data comes in.

These are raw counts of openings we've caught so far, not a ranking — too few resolved yet at a fast-enough cadence to trust a median.

Methodology

How these numbers are made

A campground only ranks once we have at least a handful of resolved openings caught on a fast enough census cadence to trust the bound between our two observations. The median is the middle value of the last 20 such openings, newest first. This is a detection bound, not a rebooking time: a date leaving the grid is not proof anyone booked it, and an opening could have vanished sooner than our next check caught it.

Want the next opening at any of these? Each target page has a scout that emails you the moment it happens — campsites.
