I have only had the pleasure of playing Nairn once, Sep 29th of 2021. Thus I cannot comment on any changes. I enjoyed the challenge of the course that day, wind against going out and at our backs coming in, it was a stern test. The conditions were impeccable, the course maintained and presented to the highest standard.
As for the course as a whole, the holes I remember most are 3 & 4 on the outward nine and 13 & 14 on the inward nine. I do remember the 9th and the Bothy but it’s the Bothy I mostly recall. The interesting thing about 3 & 4 plus 13 & 14 are these holes turn away from or play directly towards the coast line as opposed to being parallel to it.
Anyway, I hope to get back there again someday. I think Nairn is a course one needs to play multiple times to fully appreciate.
