Length 66 km (41 mi)

The River Aff is a small, scenic waterway in Brittany, France, flowing through areas like La Gacilly before joining the Oust. In summer, the water temperature typically ranges from 17°C to 20°C (63°F to 68°F), providing comfortable conditions for light water activities. However, due to its size and shallow sections, it’s not widely used for swimming. Still, there are occasional safe, calm spots along the river where locals and visitors may take a refreshing dip, especially on hot summer days, though organized swimming areas are rare.

Instead, the Aff is popular for canoeing and kayaking, with its gentle currents and picturesque banks making it ideal for leisurely paddling. The river’s meandering path through the Breton countryside attracts those interested in exploring the region’s natural beauty rather than traditional swimming. If swimming is a goal, it’s best to check with local tourism offices for recommendations on safe spots, as water quality and access may vary in this rural waterway.
