X3 on Trailer Village for the South Rim. Full hookups and the shuttle bus stops at the CG entrance.
From South Rim to Bryce/Zion, my suggested route is route 67, 89 then 89A to rejoin 89 at Kanab. For the North Rim, the RV Park with FHU at Jacob Lake is
Kaibab Camper Village. Good food at the Jacob Lake Inn.
At the North Rim, Point Imperial and Cape Royal are well worth the drive. IMO much better views than from the North Rim Lodge area.
At Bryce Canyon, Rubys is FHU and right at the park entrance. While in the Bryce area, just a few miles away is Kodachrome State Park.
X2 on driving route 12 to Torrey. A few miles from Torrey on route 24 is Capital Reef National Park.
