St. Lawrence River National Park

Explore the islands, islets and peninsulas that dot the St. Lawrence River between Kingston and Brockville.

Scattered throughout the St. Lawrence River National Park are lusciously vegetated islands, ranging from tiny rock formations to cascading mountains and fields, many with small abandoned settlements on them. Tour the Thousand Islands, one of the most popular natural attractions in Ontario.

Visit the St. Lawrence River National Park between May and mid-October for full access to the park’s many services. Specific winter sports are offered throughout the colder months, including cross-country, skiing and snowshoeing. Many trails and offices operate in the park year-round. Embark on a hike from one of the trails that depart from Brockville or Kingston, the two major towns in the area. Drive across the International Bridge or along the Thousands Islands Parkway for spectacular vistas throughout the park. 

Charter a boat from Brockville to see the park from the water. The region is rich in aquatic species, making fishing and diving popular activities on the river. Join a dive tour to see some of the most revered freshwater wreck dive sites in the world. See how many of the 21 granite islands and many smaller rock formations you can find during the day. 

Discover the rich heritage as you explore the islands, which have long been important areas for the Haudenosaunee and Mississauga Anishinaabe people. Visit the historic sites on the islands as you explore the pitch pine forests that surround them. Embark on one of the popular Jones Creek Trails for a full day of exploring the park on foot. Along the trail you can reach the park’s campgrounds, scattered across multiple islands. 

While this stunning national park spans over 50 miles (80 kilometers) along the St. Lawrence River, it has only 6 square miles (9 square kilometers) of land.

The St. Lawrence River National Park stretches between Kingston and Brockville and can easily be reached by car, boat or bus. Access to a car gives you full mobility throughout the park’s various regions. Parking is available throughout the area.
