There really isn't another course with which Painswick could be likened, in my experience. Its extreme quirk remains, somehow, fun. That it held the interest and affection of a host of GCA visitors for several days suggests that for all its madness there is a quality there which brings satisfaction each time the course is played. Sean has mentioned one or two courses in the region which have something in common. I'd probably cite Church Stretton, Windermere and Wrekin as having something similar in the vertiginous nature of some of the golf, Bala and Ffestiniog, too, although these two are much more primitive. The original 12 holes at Macclesfield have some of the mad mountaineering qualities of the higher bits of Painswick, but the new holes added to bring the course up to 18 holes are rather more sober! Parts of Halifax, Baildon and other Pennine courses such as Mellor & Townscliffe and Brampton might remind of Painswick, but these are all such distinctive courses that they have abundant unique character of their own. I seem to remember a great deal of Quirk at Dollar, not far from Gleneagles, but it is a long time since last I was there.
