YOUR ISLAND ESCAPE AWAITS. Tucked along the shoreline of the St. Mary’s River on beautiful Sugar Island, Michigan, Sugar Island Marina & Resort is a waterfront escape where nature, adventure and meaningful moments come together.

Wake to peaceful river views. Spend the day fishing, exploring the water, gathering with family or simply slowing down beneath the trees. As evening settles over the island, reconnect around the waterfront and enjoy the kind of quiet that is increasingly difficult to find.

Whether you come for a family getaway, romantic escape, fishing adventure, intimate celebration or simply a few days away from the ordinary, this is a place to settle in, breathe deeply and make memories that stay with you.
