Founded in 1901, the Castlerock Course is a classic links course in the dunes of the Causeway coast. Only around 20 minutes by car from the Royal Portrush Golf Club and the Portstewart Golf Club, Castlerock has nothing to hide behind its famous neighbors. Originally comprising just 9 holes, the course was extended to 18 holes in 1908 by the Scotsman Ben Sayers.
