Vinnie Ha Ha Landing provides public boat access to Lake Koshkonong with a parking lot and pier, serving as an alternative launch point to help distribute pressure on other busy access sites.

The launch features minimal amenities and is noted as having poor launch conditions with shallow water (approximately one foot deep), making it better suited for smaller boats or canoes/kayaks rather than larger motorized vessels.

This access point also borders the Koshkonong Wildlife Area, offering opportunities for wildlife viewing and paddling exploration.
