Large marina with extensive covered slips, multiple buildings, and a spacious surface parking lot containing numerous vehicles adjacent to the water.
Sunnyside Marina is the premier marina on the St. Croix River, just south of the historic lift bridge in Stillwater, MN. The member-owned, professionally managed marina offers recreational boating access with nearby trails, shops, and restaurants.
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.
