Thousand Islands Ontario Canada Postcard

The Thousand Islands region spans the St. Lawrence River along the border of Ontario, Canada and New York, USA, with over 1,800 islands scattered across sparkling blue waters. On the Canadian side, the heart of the area lies near Gananoque, Rockport, and Kingston, where granite outcrops, pine forests, and historic cottages create a picturesque landscape. The river channels and bays provide excellent boating, kayaking, and fishing opportunities, and the scenery changes dramatically with the seasons—from lush summer greenery to vibrant autumn colours. Highlights include cruises past island castles such as Boldt and Singer, exploring Thousand Islands National Park with its small camp-friendly islands, and visiting historic sites tied to Indigenous peoples and early settlers. The region is also known for bird-watching, scuba diving among shipwrecks, and sampling local specialties like fresh St. Lawrence fish and the original Thousand Island dressing. Its mix of natural beauty and rich history makes it one of eastern Canada’s most beloved waterfront destinations.
