i think it is a great resource.
have used this each time i’ve been to the UK. most recently 10 days in Wales. yes, some spots are not ideal, but with the use of google streetview (where available) or google earth it is quite easy to discount most spots.
with streetview you can even read the number on the height restrictions!
some spots are a bit crowded, like Freshwater Bay the other month, but then some spots are deserted.
worst experience was coming off the M1 to park up somewhere near Dunstable. the carpark was a lookout spot and was full of people sitting in their cars. was like something out of the movies. way too busy and the carpark was pissed. ended up on some service road beside the M1… 😀
have oinly ever had to pay once for a night; somewhere near Bambrugh Castle.
I’m quickly going off those wild camping lists.
Anything mildly desirable will have quickly attracted remedial measures such as height barriers or no overnight parking signs.
this is one of the advantages of a Transpoter…. you can get in just about anywhere.
shame the UK doesn’t have something similar to Aires or Stellplatz like in France and Germany.
