How to locate dispersed/primitive camping locations
I'm in south Louisiana, so we travel a good ways to do any camping. as already mentioned on an earlier post, there is not that much primitive camping east of the Rockies as compared to west of them. we go to Georgia good bit and usually stay at state parks like Vogel and Amicalola, but have found a few primitive spots around. (usually really remote and hard to get to and honestly...not worth the hassle)
we go out west a lot and just did a long trip out in New Mexico and Arizona in April where we primitive camped most of the time. I have maps and several online apps I use, like the Dyrt, and they do a decent job of showing primitive spots to camp. a year or so ago, we did a month out in Utah and Colorado and the wife was on her phone google searching primitive camp spots and actually did better finding places using Google on her phone than I did with some paid maps I ordered that were supposed to show everything in that area. I know there are a lot of apps for finding camping, so maybe check out one or two and use that as a reference and then try the Google search and see what you find once you are more in that area. my wife does most of the navigating and even her routes are usually faster and better that what I come up with using maps and apps. go figure...
the best way to find locations is to actually go to that area and see for yourself. I know that you don't want to set off not knowing anything, so like I said earlier...use an app like the Dyrt and find one you are sure of and then once you are in the area, you will find places where others are boondocking and you can just make notes of where they are for next time. a lot of the places we boondock we find by accident once we are in the area. most of the boondocking out west is BLM land and we have just popped in several ranger stations and asked them where we can camp. we did that at Carlsbad caverns and the ranger there gave us a sheet of paper with a map showing the places that were BLM land.
if we are going to a new area we don't know much about, we will find a campground online and make sure we have a place to sleep and then do recon once we are there and then switch over to primitive camping once we get a feel for the area. but yeah...Google has actually worked best for us when looking for primitive camping
