Long Sault Parkway/Mille Roches Campground
Overview
Mille Roches Campground is the largest camping area situated along the scenic Long Sault Parkway. Nestled on two islands in the St. Lawrence River, this park offers a unique island-hopping experience for RVers. It is renowned for its mature forest canopy and proximity to the water, providing a peaceful retreat that blends natural beauty with local history. Travelers often visit for the sense of seclusion while remaining easily accessible from the mainland.
Location & Surroundings
Located between Cornwall and Brockville, the park sits within a string of islands created by the flooding of the St. Lawrence Seaway in the 1950s. The surrounding archipelago offers breathtaking views of the river and lush greenery. Because it is part of the Lost Villages region, the landscape carries a quiet historical significance. Visitors will find themselves surrounded by clear water and tranquil roads perfect for cycling or leisurely drives between islands.

- Clean comfort stations equipped with hot showers and laundry.
- A centralized dumping station for convenient waste management.
- Easy access to a sprawling sandy beach and boat launches.
Nature trails wind through the islands, allowing campers to explore the local flora and fauna right from their campsite doorstep.
Nearby Attractions & Things to Do
Beyond the campsite, the Long Sault Parkway itself is a major draw for scenic biking and photography. History buffs can visit the nearby Lost Villages Museum to learn about the communities that were submerged during the river’s transformation. Water enthusiasts will enjoy the multiple boat launches and excellent fishing spots for bass and walleye. For a change of pace, the Upper Canada Village living history site is a short drive away, offering a glimpse into 19th-century life.
Who This Park Is Best For
This destination is ideal for outdoor-loving families and couples who enjoy a rustic, nature-focused atmosphere without sacrificing basic conveniences. It is a fantastic choice for those who travel with kayaks or bikes, as the geography is perfectly suited for active exploration.

The camping experience here in the summer is unparalleled, and the multi-lake terrain is very pleasing to me as a water lover.I noticed a lot of people RVing or tent camping, swimming and fishing here.The park is also very well stocked with all kinds of amenities and is clean and ready for use.

We loved tent camping on a waterfront campsite! The site we booked was private and quiet and down the road from the registration building and washroom facilities. We did have 2 nights of heavy rain and a little during the day, however we made the most of it! When the sun was out, it was beautiful! The grounds are very well maintained. Yes there are racoons and other little critters but you have to take your precautions as you would at any campsite. There are lots of garbage bins near the main building and recycling. The registration building sells of course wood and has has an ice cream cooler, drinks, chips and other souvenirs. They were out of ice when we were there but there is a Tim Hortons and gas station not to far as well. The staff on site was caring and helpful. Our car broke down during our stay and they were understanding of the situation as we had to get it towed. Special thanks to Ayaa & Luna :) sorry if I misspelled your name

Nice campsite with interesting surroundings to walk out to. Relatively clean, with somewhat close spacing between sites - maybe that was just our section. When booking, be careful about picking a site without too much incline. Some are very steep for a tent.

Postive: Sites are well spaced and/or treed for privacy. Many of the sites have direct access to water to fish or use your kayak. Some sites have great views of the river. Most visiting campers were quiet and respectful of others. We had great moonlight views over the river. Negative: The park sites are a challenge to find level ground for trailers and tents. Washrooms are limited and need more attention for the number of campsites.

Nice camping, but the bathrooms are dirty and insufficient. You have to wait a long time to take a shower.
