The best time to visit Grenville-Sur-La-Rouge is during the summer months, from June to August, or in the autumn, from late September to October.
Summer offers the warmest weather, making it ideal for outdoor activities on the Rouge River, such as rafting and kayaking. The surrounding natural areas are lush and great for hiking and exploring. This period is particularly good for families looking to enjoy water sports and nature in comfortable temperatures.
Autumn provides a spectacular display of fall foliage, with the maple trees transforming the landscape into vibrant reds, oranges, and yellows. The cooler, crisp air is great for hiking and scenic drives along the historic roads.
