Fairfax Boat Ramp is one of nine boat launch locations on Monroe Lake, Indiana's largest body of water, providing access for both motorized and non-motorized watercraft.

The Fairfax State Recreation Area also features a public beach (open Memorial Day through Labor Day), modern bathhouse facilities with showers and restrooms, picnic areas, and a marina with seasonal mooring and services.

Indiana lake permits are required for private boats, and the area is located on the southwest side of Monroe Lake near Fourwinds Lakeside Inn & Marina.
