Canyonlands RV park in town. They also have small cabins. Decent restrooms/showers. They dont complain about stuffing your site full and they have extra parking for trailers down by their creek/tent area. Walk to restaurants, bars, grocery and gas station is at the entrance.
We had 5 Jeeps with minor to major modifications ranging from 31's 35's and one with 37's or 40's. We did Kane creek, steel bender, Golden Crack, Poison spider, Moab Rim.
The Lasalle loop road and off shoot roads to Lasalle mnt area is a nice ride and not 4x4 only.
