The Hewitt Street Boat Ramp is a public launch point on Gull Lake in Gravenhurst, Ontario, located at 1101 Hewitt Street. It offers both sand and dock entry options, making it accessible for a range of watercraft including canoes and kayaks.

Parking at this site is limited, so arriving early is advisable. From this launch, paddlers can explore up to 10 kilometres around the Gull Lake perimeter, with difficulty ranging from easy to moderate depending on conditions and distance.

Points of interest on the lake include Lily Bay, known for beaver dams, marshes, and water lilies, as well as Gull Island, where submerged rock formations warrant caution.
