Lac du Cos is a compact 20-hectare mountain reservoir in Savoie offering bank fishing for trout, pike and perch in stunning Alpine surroundings—though it's worth noting this is primarily a trout water rather than a carp venue. Day fishing only (no night sessions) and strictly bank-based, so you'll need to plan your approach accordingly on this 440-mile trip from Calais. Check with the local AAPPMA (Amicale des Pêcheurs de l'Arc, based in La Chambre) for a day ticket before arriving, as this is a controlled water.
