When do Prospector reservations open?

The White River National Forest says most of its developed campgrounds open on recreation.gov about 6 months ahead. That's a forest-wide statement from Feb 2025: the Prospector pages don't restate it, so check which dates are on sale before you plan around a release day.

The pages we checked don't give season dates for Prospector, so check its recreation.gov page for the dates on sale. Recreation.gov lists every site as reservable. It also lists drinking water, but the Forest Service page says the well is dry, so confirm before you go.

Rules verified Nov 8, 2026 against the Forest Service page, recreation.gov and the White River National Forest's reservations notice. Rules change: check before you book.
