Fisherman's Road Boat launch is a nice boat launch on Lake Winnebago on the east side of the lake. Only a short drive from Fond Du Lac. It features one of the few lighthouses that are on Lake Winnebago with a small protected area so you can get out quick on the water.
Please be aware of muggles as it can be busy and replace as hidden.
This boat launch is one I frequently visited last summer when I would launch my sail boat due to the small distance needed to get out in the open water. Sadly one of the visits, I went out in the sailboat and came back in the sheriffs boat due to my boat capsizing and then sinking. That was a lot of fun plus you can catch a go pro video of the action with my friend here.
