Medium-sized marina with multiple piers offering numerous slips, adjacent to a striped asphalt parking lot with moderate vehicle presence and surrounding residential buildings.
Sister Bay Marina is located in the village of Sister Bay, Wisconsin, on the western shore of Green Bay, which is an arm of Lake Michigan in the Great Lakes region, surrounded by the scenic bluffs and forests of Door County. This marina serves recreational boating and sailing activities, catering to those exploring the protected waters of Green Bay and the nearby islands of the Door Peninsula.
Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
