I am possibly looking at taking a trip up the Blue Ridge Parkway and to Skyline Drive. I would like to camp most of the way. I know that there are dedicated campgrounds (with fees). What type of backcountry (non-established campsites) camping options are there? Can you just pull off the road, go out of sight and set up camp. I am looking at doing very low impact camping. I would like to hear what others have done and what regulations there are. Is it less restricted where the parkway runs through National Forests? Any information would be appreciated.
