Idlewild Golf Club sits on a rolling parcel of land just outside Sturgeon Bay, where northern hardwoods and stands of white pine frame the fairways. The original nine holes were laid out in the late 1920s, with a second nine added decades later; both sections share the same bent-grass greens and a routing that repeatedly crosses small spring-fed creeks. Several holes play along the edge of the wooded ravine that gives the course its name, while others traverse open meadows where prevailing westerly winds can alter club selection. The layout features modest elevation changes, natural sand outcroppings, and a collection of restored native-grass areas that serve as both rough and wildlife habitat. Maintenance practices emphasize minimal chemical inputs, and the club participates in the Wisconsin Audubon Society’s sanctuary program. A modest white clapboard clubhouse houses a small pro shop and grill that overlook the ninth green.
