The Grand Marais Trail is the name of a small bicycle trail that follows Turkey Creek (also known as the Grand Marais Drain) in the middle of Windsor, Ontario. It starts off as a minor spur route, connecting the West Windsor Recreationway with Huron Church Road and the neighbourhood of South Windsor (via a tunnel under Huron Church Road, and light at Grand Marais Rd. if the tunnel is closed).

The trail begins as a link to the West Windsor Recreationway, and travels along Grand Marais Road, with a spur branch heading south and under Huron Church Road. The trail continues along its own alignment before leading to bike lanes at West Grand Boulevard. The original path only travelled as far as Balmoral Avenue and California Avenue (both residential streets) until very recently, having been constructed as either a gravel or concrete-paved trail.

Bike lanes continue along both sides of Turkey Creek (Grand Marais Road West, and West Grand Boulevard), with a trail bypass heading along Academy Drive and Radisson Court West, before becoming its own trail between houses and Turkey Creek. The trail's three branches all meet up at Bruce Avenue (which is the main thoroughfare for vehicular traffic as well as cycling traffic heading to and from Grand Marais Road), where the routing continues along West Grand Boulevard. In between the three alignments, a bridge connects the Grand Marais Road bike lanes to the "bypass" (along Academy Drive) and to West Grand Blvd.'s bike lanes at Virginia Park Avenue.
