About Clark's Marina
Clark’s Marina is nestled in a peaceful setting in the Bateau Channel, 2 miles west of Gananoque Ontario Canada and due North of the J17 marker. This completely sheltered harbor is protected from the rough and open waters of the St. Lawrence River. Families from all over Ontario, Quebec and The United States gravitate to our marina for the a stress-free boating experience. We realize that there are only so many weekends and days off during the season; have them relaxing on the water in the best boating destination in Ontario.
