Old Colner
Club Champion
The course I was most surprised with in the area (I played it 3 weeks ago) is Newbiggin. After arriving with no expectations and paying the modest £35 green fee, we were pleasantly surprised. A bonafide links course so maybe not what you are looking for to tag onto your main three, but some really interesting holes once you head out to the sea.
I played at Newbiggin while in the area on holiday recently, loved it and only paid £15 County Card rate on a Sunday afternoon, the course was deserted.
