Mille Roches Campground & Beach Unavailable for 2026 During Major Improvements
Mille Roches Campground and Mille Roches Beach & Day Use Area will be unavailable during the 2026 season, while undergoing major infrastructure improvements to strengthen guest amenities and modernize essential services.
These investments will deliver new, accessible gender-neutral washrooms and a new, modern trailer dump station at the campground, a new canteen with washrooms, changerooms, outdoor rinse showers and a licensed patio at the day-use area, and improved water and wastewater systems. These upgrades will enhance guest comfort, safety and accessibility in future seasons.
The Long Sault Parkway will remain open throughout construction. Guests may see construction activity and short periods of single‑lane traffic near work areas.
We appreciate your patience and encourage guests to explore other Parks of the St. Lawrence campgrounds and day-use locations during this time. There are seven alternative Parks of the St. Lawrence Campground with similar amenities within a 30-minute drive of Mille Roches campground.
