This town was the birthplace of the floating timber in Mauricie, which stopped in 1996 after 150 years. Grandes-Piles proved to be a historic landmark in the forestry industry. Since 1996, the reopening of the waterway free of floating logs, the Saint-Maurice River offers to boaters a large choice for water sports and a paradise for sailing. In winter, the frozen river and snowy cliffs and forest become a huge area for winter sports. Boating is generally done well between the dam of Grand-Mère and the dam of La Tuque, especially when the water is high.
