I would like to put forward Arrowtown Golf Club in New Zealand as a course worthy of this discussion.
While it doesnt feature on any world 100 lists, it most definitely ticks a lot of boxes when discussing great courses.
It wasnt until some time after my first play that I even realised the course had 5 par 3's. This to me is a sign of an "anomaly" being incorporated so well that it doesnt present itself to the player is an obtrusive manner. Also, the course features no bunkers which I also did not realise until later.
The first hole plays 162 metres down hill to a semi obscured green. Landing short can propel your ball through the green. Playing long leaves a downhill chip:
The sixth hole plays 133 metres across a gully to a green that offers very little support yet demands a shot that is best carried onto or just short of the surface:
The twelfth plays 156 metres slightly downhill to a green with a large bank to the left. A soft ridge running through the green can magnify how far a ball will move right if playing away from the bank:
The Fourteenth plays 187 metres uphill to a green which falls away to the left. The natural contours support sliding a ball in right to left off the slope on the right of the green. For me, this is one of the most fun shots I have and best par 3's I have personally played.
The final par 3 sixteenth, is possibly the quirkiest and most fun. It plays 139 metres to a green set in a tight little saddle. The green slopes off both the front and back so distance control is premium. It is very easy to push or pull a shot from the tee and leave the most interesting of recovery shots. It is also possibly the smallest green I have seen and I paced it to be approx 190m2 (Idont know what that is in sq feet.) It is less than 10 metres wide in the middle. The second photo highlights just how small and sloping it is.
