You will see a blue Container that says Stand-up Paddleboarding on it. It is the south end of Diversey Harbor but north of Fullerton. Enter the launch area across from the Nature Museum. Note: it is not the main Diversey Boat Ramp. We are south of there.
Parking is free along Cannon Drive north of Fullerton, a short walk from the launch.
Paid parking is available in the lot right by our container but it is $22.
