I have not been for about 15 years but fishing never seemed to be advertised much in those days either. Although there are a number of lakes only a couple had fishing allowed. Look out for signs PESCHE INTERDITE which translates to fishing prohibited. We fished the lake adjacent to the pool park and the shallow one up near the golf course, close to the Chataeu. Plenty of daft carp present.
Just back. Fished shallow lake near chateau and cricket pitch. 1 foot deep waste of time.
Fished lake with pedallos on it and sacked up every morning with up to 60kg in three hours, carp from 1 to 7kg.
There was another lake out back with carp in it to 30. Gave it a go one evening and hadn’t much but a carp of about 14lb and a huge roach on halibut pellet.
You’re dead right, its one of the biggest sites in northern France and they couldn’t give a toss about fishing and had no information to offer me despite some excellent fishing being on site.
That’s the French for you.
