Grays Lake is a 166.6-acre urban lake in Des Moines offering convenient paddling opportunities with views of the city skyline. The lake features a designated boat launch near the northwest parking lot for personal watercraft, plus rental facilities at the Christine Hensley Terrace on the southwest shore.

Watercraft rentals include 2- and 3-person canoes, double kayaks, stand-up paddleboards, and pedal boats, available from May through Labor Day. Life jackets are required and provided free with rentals. Rental hours run 10am-8pm daily during peak season (late May through early August), with reduced hours in shoulder seasons. All watercraft must be returned 30 minutes before closing.

Important safety regulations include: - No watercraft rentals when winds exceed 17 mph - No rentals after 7pm - Children 13 and under must be accompanied by an adult - All users must sign a waiver - Operations may be suspended during rain or when temperatures fall below 55°F

The lake is encircled by the 1.9-mile paved Kruidenier Trail, which includes the illuminated Chris and Marcie Coleman Bridge. Facilities include restrooms, concession stands, parking lots, and a beach area. The southwest parking lot and dock area will be undergoing improvements from October 2024 through spring 2026, but three other parking lots remain available.

Wildlife observers may spot bald eagles, as there is a nest visible on the northern shore. The lake connects to other trail systems in the Des Moines area, making it a central hub for outdoor recreation.

Starting in 2024, the city plans a $2 million renovation of the paddle craft marina to improve environmental resilience and add features including an upland viewing deck, ADA-compliant pathways, and improved shoreline infrastructure.
