Massive, almost mountainous dunes impose on this brilliant Willie Park Jr. layout. Furthermore, panoramic views of the Atlantic Ocean and the Lough Foyle to the Inishowen Peninsula await, making Portstewart among the best-looking golf courses in either Ireland or Northern Ireland. Thankfully, it plays as good as it looks, with a handful of brilliant holes and a set of excellent greens. As far as golf trips to Northern Ireland go, this is a cannot miss golf course, alongside County Down and Portrush.
