Watch the weather as during wet times the washes may flood, and the dirt can get muddy.
Long RVs and folks towing trailers need to beware of many steep, sharp dips through dry washes especially coming in from the west entrance off Highway 261. Towards the middle sections, the road is quite narrow with tight curves.
Off Highway 163 to the east has some larger RV accessible campsites and less drastic dips. We were able to tow our 30-foot fifth wheel in 4 1/2 miles coming from that direction.
