A secondary site near the Rivière des Mille Îles allows rental of aquatic equipment for activities such as kayaking, canoeing, Rabaska, and stand up paddleboarding.

Mountain biking facilities are also present on this site for training and competitions during the summer months.

The GPAT ensures the maintenance of these two dozen kilometers of paths through the woods with one of its specially built groomers.

In 2016, the GPAT, in collaboration with the city of Terrebonne, hosted the mountain biking competitions as part of the Jeux du Québec (Quebec provincial games).
