Grand Marais Golf Course sits in Cahokia Heights, Illinois, a community in the Metro East region across the Mississippi River from St. Louis, Missouri. The course occupies land in the American Bottom, the broad floodplain that stretches along the eastern bank of the river in southwestern Illinois. This flat, low-lying terrain is characteristic of the area, which has a long history of settlement dating back to the ancient Cahokia Mounds civilization nearby. The course serves as a public facility for the surrounding communities in St. Clair County. Like many municipal courses in the region, it provides accessible golf in an area where the landscape is shaped by river hydrology and agricultural use. The routing likely reflects the constraints and opportunities of floodplain topography, with minimal elevation change and design considerations related to drainage and water management common to courses built on such sites. Grand Marais functions primarily as a local amenity rather than a destination layout. The course offers straightforward golf for residents of Cahokia Heights and neighboring towns in the Metro East, contributing to the network of public courses that serve the greater St. Louis metropolitan area. Its setting in the American Bottom places it in a landscape of historical and geographical significance, though the course itself maintains a modest profile focused on community recreation.
