Located halfway between Montreal and Kingston, the Long Sault Parkway is a chain of 11 islands spanning more than 10 kilometres through the St. Lawrence River. Created during the construction of the St. Lawrence Seaway, the Parkway offers a quiet natural setting that is easily accessible, just minutes from Highway 401. Visitors can enjoy beaches, bike paths, nature trails, picnic areas, boat launches, scuba diving, and some of the region’s most popular fishing spots, all within the St. Lawrence River corridor.
Home to waterfront campgrounds with over 600 sites.
Part of the Great Lakes Waterfront Trail perfect for all levels of cycling experience.
Perfect for a picnic, swim, fishing, or enjoy a relaxing day outdoors along the St. Lawrence River.
To support visitor safety and privacy, recreational drone use is not permitted on any Parks of the St. Lawrence properties which include campgrounds, beaches, and day use areas, without written permission. Recreational use includes flying drones for personal photos or videos, social media content, and family or leisure activities. Under Ontario Regulation 1023, drones are considered aircraft by Transport Canada. Aircraft are not permitted to land or operate within Park boundaries except at licensed airports under the Aeronautics Act (Canada).
The Long Sault Parkway was built in the 1950s during the construction of the St. Lawrence Seaway, which transformed the St. Lawrence River into a major shipping route. Several riverside communities, later called the Lost Villages were flooded as part of the project. The highest points of land from these communities were saved and carefully linked together to create the Parkway.
Today, the islands along the Parkway are reminders of the Lost Villages, offering guests a unique connection to the region’s history.

A daily vehicle permit or Annual Day Use Vehicle Permit is required for anyone stopping at any location along the Long Sault Parkway, including activities such as fishing, picnicking, boat launching, sightseeing, hiking, and more.

The St. Lawrence Parks Commission is undertaking a major project on the Long Sault Parkway. This work is part of a broader investment designed to enhance guest amenities, support the long‑term environmental sustainability of SLPC parks and modernize critical water and wastewater systems by connecting to the Township of South Stormont’s municipal networks.
The Long Sault Parkway will remain open throughout construction, and will remain accessible for driving, walking, and cycling. Guests may see construction activity and short periods of single‑lane traffic near work areas. SLPC will work closely with construction crews throughout the project to minimise disruption.

The Long Sault Parkway offers some of Eastern Ontario and Western Quebec’s best fishing, with easy access from multiple boat launches. Hoople Creek Basin is well-known for its trophy pickerel (walleye), giving anglers excellent opportunities to land a big catch. After a day on the water, relax in nearby cabins or campground and enjoy the surroundings. Whether casting from shore or venturing out by boat, the scenic waterways of the Parkway offer great fishing.
Lock 21, just off Macdonell Island, is a popular scuba diving area. This historically significant site features a submerged 19th-century Victorian canal lock and the remains of the Lost Villages, offering divers a unique glimpse into the past. With depths around 60 ft and strong currents, it’s a challenging dive best suited for experienced divers. The area is accessible from the Long Sault Parkway, which also offers boat launches and nearby facilities for a great outdoor adventure.
