Funny to think that on my Scottish trip this year I slotted in Prestwick last as an afterthought, only to have the experience be tied for the best with North Berwick on a trip that also included Cruden Bay and TOC.
I urge fellow GCA'er to go to Prestwick. If your near Edinburgh, it is worth the two hour cross country trip. Better yet, stay in the small town of Prestwick and play it more than once.
My top three holes:
#13 Sea Headrig - Possibly the best green complex in Scotland? Agree with Ran 100%
#15 Narrows - The personification of a blind hole in golf. Up, down, over, and around. Extremely fun to play.
#17 Alps - Tough to beat the original along with the enormous and deep Sahara Bunker.
