Hi mate.
Went to a place called Val Dore Lakes a couple of years ago. First time I had fished abroad and it was awsome. Took my young lad and he loved it. We didn't catch many fish but other people had large numbers of carp and catfish.
Got on a ferry from Dover and it is only an hour and a bit drive from Calaise.
Prices seem reasonable compared to other places in France.
Check out the website at www.valdore.com.
Hope you find what you want and tight lines.
