Whistling Straits Irish Course sits on the western shore of Lake Michigan in Sheboygan, Wisconsin, where former farmland was reshaped into a links-style layout. The terrain features rolling dunes, native fescue grasses, and deep bunkers that resemble those found on traditional courses along the Irish Sea. Wind off the lake frequently influences play, especially on holes that run parallel to the shoreline or rise over exposed ridges. Several fairways are bordered by low stone walls and tall rough, creating tight landing areas that reward accuracy over distance. The greens are built on natural plateaus or tucked behind mounds, often requiring approach shots that account for elevation changes and shifting wind direction. The course uses minimal tree cover, relying instead on the contours of the land and the strategic placement of hazards to define each hole. Sand and native grasses dominate the visual landscape, giving the course a rugged, windswept appearance throughout the year.
