Adz, that link seems to be dead, but I've driven on some of pilgrims way and it has some great views. I think it has some sort of seasonal closure on it, but I could be confusing it with the Ridgeway, in fact as I type, I'm almost certain its the Ridgeway thats partly closed for the winter. I have a couple of OS maps for the area and there are quite a few little BOATs there (Byway Open to All Traffic). Last time I was there we suffered a little rambler rage and almost had a new hood ornament in the shape of a speeding scrambler bike.
