RV travel guide
Washington County
County seat St. George, 2,426 sq mi across Utah. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.
The county in brief
A traveler's read on Washington County
St. George's metro has been the fastest-growing US metropolitan statistical area five of the past ten Census years per the BEA — population doubled between 2000 and 2020 and the practical RV impact is that Washington County campgrounds (Zion-side Watchman + South + Snow Canyon SP + Sand Hollow SP) book the spring-break and shoulder-season weeks 4-6 months ahead via recreation.gov. The county sits at the Mojave-Colorado Plateau transition, with elevation running from 2,160 ft at the Virgin River basin to 10,365 ft at Pine Valley Peak in the Dixie National Forest. Zion's eastern Mt. Carmel Tunnel (1.1 mi) caps any rig over 7'10" wide or 11'4" tall to a paid one-way escort window — the single hardest planning constraint for southern Utah RV trips.
