Long Sault Parkway Campgrounds


The Long Sault Parkway is a series of 11 islands that were created from high points of land left after the flooding of the St. Lawrence River during the construction of the Seaway in the 1950's. In fact, several villages once stood where the river now lies, a fascinating story captured at the Lost Villages display on Macdonell Island.


Please see each location for the scheduled programming activities, which may differ at each campground.

Mille Roches Campground
Mille Roches Campground

Spread over two islands, the campgrounds of Mille Roches offers seclusion and tranquility set amidst a forest canopy of mature trees. Of 214 campsites, Mille Roches has the largest number of waterfront sites among the Parks of the St. Lawrence, with 63 sites along the wooded shores. In 2013, we added a new cabin called the Dive Shack on Macdonell Island (also known as Lock 21).

Woodlands Campground
Woodlands Campground

As its name suggests, Woodlands Campground is located in a beautiful wooded setting facing Lake St. Francis. Its location is ideal for watersport beginners. It boasts the most memorable sunsets in the area which you can enjoy from its two sandy private beaches. In 2013, thirty new 50 amp RV sites were added along the campground's eastern shoreline along with two beach-front Mini Cabins

McLaren Campground
McLaren Campground

McLaren Campground has undergone a major renaissance with 113 of its 206 campsites being upgraded to full RV capability with 32 new 50 amp sites and five camper cabins, all named in honour of the Lost Villages. We have also introduced several new pull-through sites for quick set ups and easy getaways and four new exclusive waterfront sites at Hoople Island.
