Riverside serves as the third course at Portstewart Golf Club, complementing the championship Strand layout and the shorter Old Course in this Northern Irish coastal town. Designed by Des Giffin, the course occupies lower-lying terrain inland from the dramatic duneland that defines the club's flagship offering, providing a more parkland-style experience within the overall property. The routing takes advantage of the River Bann's proximity and the flatter topography characteristic of the area between Portstewart and neighboring Coleraine. While lacking the elevation changes and natural dune formations of the Strand, Riverside offers a different test with tree-lined fairways and strategic bunkering that rewards accurate play. The course functions as an accessible option for members and visitors seeking a less demanding round or serves as an introduction to the club before tackling the more exposed and challenging links terrain. Portstewart Golf Club maintains a welcoming atmosphere, with Riverside playing an important role in accommodating the full range of golfing abilities within the membership and visitor population. The course benefits from the club's overall maintenance standards and shares the clubhouse facilities that serve all three layouts. Its position in the rotation allows the club to host larger competitions and society outings while preserving the conditioning of the championship course, a practical consideration for clubs managing multiple layouts in the Irish climate.
