'town' club Rathmore and the ladies and juniors of Royal Portrush. It is shorter and considered less demanding than the Dunluce Links.

Signature holes On the Dunluce course at Portrush there are several signature holes on both the front and back nine. In particular are the fourth, fifth and sixteenth holes. The fourth hole is a long par four which is more than 480 yards from the championship tees, with out of bounds right and thick rough on the left. There are several bunkers in the undulating fairway and the green is placed between two small sand hills. The fifth hole is a relatively short downhill par four with a dogleg to the right. It has no bunkers but a heavily undulating green perched on the edge of a large drop down to the beach and has views across the White Rocks beach, and the Dunluce Castle after which the course was named. The sixteenth hole, named Calamity Corner, but locally known as just "Calamity" is a long 236 yard, uphill par three. It is played to a green over a huge ravine short and right, with mounds and hollows to the back and left of the green. Only one member is known to have made more than 1 ace at Calamity. Michael Henry made the feat in both 2007 and 2019. The Open Championship The Open Championship was first staged at Royal Portrush in 1951; Max Faulkner won his sole major championship.
