I played Portpatrick last year as a stop off on my return trip from Arran. I enjoyed playing there. Excellent views off the cliff top
As you might expect, there were strong breezes and showers but good greens and interesting holes.
I would have played Stranraer if they hadn't had a large comp on that afternoon but I was not disappointed that I played Portpatrick.
Lovely part of the country. You won't be disappointed with any of those three courses, my own favourite would be Portpatrrick out of those three. Great fun to play, great views and a welcoming clubhouse, what more could you want.
