I am a Life Member at Isle of Harris GC and last played there in the LM Tournament and then the Open in August 2016. I am currently arranging my trip for August 2018.
It is a great place to play and with the sun out, magical. The weather can be a bit severe - we played in some tough conditions last year - but that is all part of the fun. I once made a calendar from some photos of courses I had played in the year, and I was asked of the Harris photo -' I thought you went to Scotland, not the West Indies?'
If you get the chance, make the trip. I have played Askernish twice and it can be brutal if you do not keep the ball on the fairway. I hit a ball last year as a lay up, into the wind, at a mark just of the fairway. I hit it exactly to the spot and it went 2 inches into the 2 inch deep grass. I stood over it and could not see it. That is tough. That said, with the wind I did manage to play the last 5 quite well !
