Portstewart celebrated its centenery in 1994. Situated along the noth coast, and not far from its renowned neighbour Royal Portrush, Portstewart is set in land wonderfully suited to the classic links course. The modern course, through an acquisition of land from the National Trust, now has 27 holes. Seven of these were new holes were meticulously woven into the ancient course and provide for a great sense of golfing satisfaction and challenge. Many now consider the Portstewart links to be equivalent in stature to its better known neighbour.
For many years the boast at Portstewart Golf club has been that it possesses the finest opening hole in the world of golf. However this should not be taken to mean that other holes, such as the 6th and 8th, both classed as potential card wreckers, should be treated lightly. Missing the green on the 6th may confront the unwitting golfer with a difficult shot from 40 feet below the green's well guarded flag. With its excellent greens the Portstewart course has hosted several Irish Amateur Championships.
