The best time to go to Rockport, Ontario, is during the summer months, from June to August, when the weather is warm and all attractions are fully operational.During this period, the Thousand Islands region, where Rockport is located, truly comes alive. The St. Lawrence River is superb for boat tours, fishing, and watersports. The days are long, making it ideal for exploring the natural beauty of the area, including the many islands and shorelines.For those who prefer a slightly quieter experience with pleasant weather and fewer crowds, late spring (May) or early autumn (September to early October) are also excellent choices. In May, the landscape is lush and green, and in autumn, the changing colours of the leaves along the riverbanks are spectacular. Many boat tours still operate during these shoulder seasons, offering a different perspective of the islands.
