Ottawa Lake Boat Ramp provides public access to a 17-acre lake in the Kettle Moraine State Forest Southern Unit, featuring a boat launch where gas-powered motors are prohibited.

A vehicle admission sticker is required for access, and amenities include picnic tables, grills, toilet facilities, and a beach wheelchair available at the park office.

The launch also offers an adaptive kayak and launching chariot through the rental program for paddlers with accessibility needs.
