Gray's Lake Park is a 166-acre urban park centered around a former gravel quarry now functioning as a 100-acre lake. The park features a 1.9-mile paved recreational trail that loops around the water. It is most distinctive for the massive, illuminated pedestrian bridge that connects the park to the larger Des Moines regional trail network. The site offers open lawn areas, a designated swimming beach, and boat ramps for non-motorized watercraft. Native prairie plantings and restored wetlands exist within the park boundaries to manage stormwater. The area serves as a primary hub for local community outdoor recreation and exercise. The lake depth reaches approximately 30 feet in certain areas. Maintenance is managed by the City of Des Moines Parks and Recreation Department.
