Lac au Duc is a substantial 190-hectare natural lake in Brittany offering excellent mixed fishing for carp alongside pike, zander, bream and tench — ideal if you want variety without sacrificing quality carp prospects. Night fishing is permitted here, and the lake's boat access opens up deeper areas that can hold bigger fish during summer months, though you'll want to confirm current sector restrictions with AAPPMA du Morbihan before planning your session. Located roughly 300 miles from Calais, it's a worthwhile destination for a dedicated week-long trip; you'll need an AAPPMA day ticket or annual permit to fish legally.
