The two best holiday campsites for lakeside fishing (carp or otherwise) are Le Domaine de Litteau and Le Domaine de Dugny, both of which have on-site fishing lakes. Le Domaine de Litteau is also near to Les Etangs de Planquery, a complex of fishing lakes near the magnificent Château de Ballero.
Le Domaine de Dugny has the added bonus of being near to the lovely Loire River. The Loire can be up to half a mile wide, but it frequently becomes much narrower as it makes its way around islands. You can catch large barbell at many spots along the Loire, but if your fishing lets you down, many of the riverside restaurants serve it stuffed for you to enjoy with a glass of wine.
Before you start loading the car with rods and bait, it’s worth mentioning that fishing in many areas in France requires a fishing licence. You can buy these online but the rules differ between regions and types of fishing, so contact your Siblu holiday park first. We’ll be more than happy to help you arrange things.
