Kingsdown is where (apart from Harlech) I learned to play golf, and I was a member there as a junior and a student for about a decade from 1972-1982. I haven't played there this century, however.
I think that one or two others (including Sean) have commented on aspects of Kingsdown on GCA before, and especially the excellent short fourth. When I first played there c1970 the course was of thirteen holes, with the tee for the splendid ninth hole over the crossing road, making for a really tough par-four of about 425 yards (it is now about 360). Holes beyond the current 2nd hole had been lost to agriculture during WW2, truncating what is actually one of the oldest golf sites in the West of England, dating from 1880 (when the Bath Golf Club first played there, before moving elsewhere), and that pre-war layout involved still further road crossing, notably to what ( think) is now the 8th green.
I have always thought Kingsdown a breezy course of half a dozen moderate holes, half a dozen rather quirky holes, and half a dozen genuinely good holes, played on generally decent turf with some gorgeous views down the valley to Bath. To my mind it is a distinct improvement on the course at Lansdown (next to Bath Racecourse, to the North of the City), if not as good as the Bath Golf Club itself at Sham Castle. It was always a very friendly, unstuffy golf club, and the one blot was some distinctly dodgy tree-planting on essentially upland terrain.
My local Bath golf recommendation remains, however, a game on the 18-hole approach course behind the Royal Crescent, a pitch-and-putt with (in summer) some of the fastest greens and at all times the most spectacular urban backdrop of any golf course in England. Burnham is about 90 minutes away, and Porthcawl perhaps two hours, but in all honesty Bath has enough non-golfing assets to occupy happily most visitors!
