Zion's Watchman and South campgrounds hold barely 300 in-park sites for nearly five million visitors. CampWatch monitors every cancellation on Recreation.gov and emails you the moment a site opens.
Zion drew nearly five million visitors in 2025, making it the second-most-visited national park in the country. Every one of them is funneled past just two in-park campgrounds — Watchman's 176 sites and South's roughly 130 tent sites — creating competition unlike almost anywhere else in the national park system.
Watchman opens on Recreation.gov exactly six months ahead of your arrival date, and peak weekend nights routinely sell out within the hour of release. South campground books on a 14-day rolling window that is watched just as closely by experienced Zion visitors who know exactly when to check.
The moment a reservation drops on Recreation.gov, CampWatch catches it and alerts you to claim it first — no manual refreshing, no missed windows.
