The Mussenden Course is the championship offering at Castlerock, with holes routed through majestic sand dunes. Golfers enjoy views out to Scotland and the Isle of Islay on a clear, sunny day. The Mussenden is certainly not the longest course that golfers will ever face, measuring in at just over 6,600 yards. Playing as a Par 73, there are chances for good scores, but there are also dangerous holes to take those scores away from you. The course begins with a pair of dog-legs to the right, the 2nd being one of the harder holes on the course despite only measuring 335 yards. The 3rd on the Mussenden is the opening par 5 on the layout, and at just 525 yards, it is reachable in two for the longer hitters. The 4th – 'Leg o'Mutton' – is a 200-yard hole with a railway line to the right, a burn and out of bounds to the left, and a raised green awaiting all those able to find it. The 5th is one of the easiest holes on the property. A par 5 at just 475 yards, the only real danger is the railway line that runs down the right side of the hole, a true links golf feature. The 6th is not the longest par 4 at 350 yards, but with a water hazard running across the front of the green, approach shots must carry to stay dry. 7 is then the hardest hole on the course, with a narrow fairway to find off the tee. The tough stretch continues through to the turn, with another 400+ yard par 4 followed by the par 3 9th. It is carded as the second easiest hole on the Mussenden Course, but at 215 yards from the tips, it’s barely easy... The back nine also begins with a tough par 4, before the 530-yard par 5 11th offers up another birdie opportunity if you can find the fairway with your tee shot. A pair of tricky par 4s follows before the par 3 14th, where the green is surrounded by four bunkers. 15 and 17 are the last par 5s on the Mussenden and sandwich the easiest hole on the course – the par 3 16th. The 18th has a raised green and many a bogey has been made by those under-clubbing, coming up short and trickling back down into the fairway, leaving themselves an exacting chip.
