This massive 613-hectare reservoir in the Ain region is a serious destination for UK carp anglers, offering genuine night fishing opportunities alongside pike, catfish and zander — perfect for a multi-species trip. The sheer size means plenty of elbow room and diverse habitat, with boat access opening up exploration of deeper sections where larger carp and catfish hold. Located 399 miles southeast of Calais, it's a worthwhile journey for an extended break rather than a quick visit.
Practical note: Night fishing is permitted but sector restrictions apply — contact AAPPMA Bas-Bugey before your trip to confirm accessible areas and obtain your French fishing permit.

France offers outstanding fishing year-round. The main coarse close season applies to some rivers (typically January–March for certain species), but still-water carp fishing on private and AAPPMA-managed lakes is available throughout the year. Spring (March–June) is the classic French carp season, with fish actively feeding and moving into shallow margins. Summer nights (June–August) are ideal for big-fish sessions on the large public reservoirs and rivers. Autumn (September–November) is particularly productive on the Auvergne and Languedoc lakes as temperatures drop. The Loire and Saône river systems produce excellent catfish sport from June through September, while the Dordogne and its tributaries fish well for chub, barbel and trout from spring through autumn.
