There appears on the Hualapai Mtn. Park site,to be RV and "dry camping" ... See if the site on Google, gives you any help... carracar
We've been thru the park in the winter. It did appear that there were tent sites in addition to RV sites and cabins. There are also some campgrounds toward Yucca.
We're starting a roadtrip in Vegas this summer and don't want to drive to long on the first day so we can acclimatize and sleep off the jetlag....So i figured that on route to Sedona, Kingman is the first place to stop get supplies and so on...
But it is only a one night stay and not in Kingman itself but somewhere close by.
The seasonal heat, will probably drive you into a motel to get that needed sleep ! carracar
Are you planning to camp at Sedona as well? It's probably the most popular place to camp in Arizona. Some campgrounds might be in the national recreation database but I'm pretty sure most are first come first served. Don't arrive on a weekend. I think dispersed camping has been eliminated except in the National Forest areas to the east of Sedona, which are not easy to reach as the road is very rough.Edited: 6:12 pm, January 04, 2013
Dispersed camping in Dutch is "wildkamperen"
