Creve Coeur Lake Memorial Park is a 2145acre St. Louis County park located in Maryland Heights, Missouri, United States. The park is the largest in the St. Louis County Parks system and includes Creve Coeur Lake, an oxbow lake which is the largest natural lake in Missouri. The park has facilities for picnicking, tennis courts, multi-purpose athletic fields, and an archery course. Creve Coeur Park includes Crystal Springs Quarry Golf Course, an 18-hole course opened in 2001. In December 2003, construction for the Creve Coeur Lake Memorial Park Bridge, which is part of Missouri Route 364, was completed. The concrete bridge connects St. Louis County to St. Charles County and crosses over the southern end of the park. The project also included Creve Coeur Lake being dredged and the addition of a siltation lake to prevent the need for later dredging. Creve Coeur Lake Memorial Park has an asphalt walking trail around the lake, which was constructed by the Missouri Department of Transportation alongside the bridge project. The trail also connects to a separate lane on the bridge leading across the Missouri River to connect to the Katy Trail. A large portion of the park and surrounding area is also wetlands, and the park has been used for conservation purposes, particularly the study of various waterfowl.
