What is the legal and practical position on wild camping in England and Wales, specifically in the Brecon Beacons National Park. I think I am right in saying that technically you need to ask the landowners permission but how much of an issue is this in reality.
I am looking to pitch a single one man tent for a single night and then move on the next day to a new location. As long as I pitch away from the path and in an unobtrusive location, how likely am I to encounter any problems? Does anyone have any experience of camping in this area and could give me some advice? Also what about camping in forested areas. I will be using a self-contained stove so fire isn't a risk but am I likely to run into any other problems?
