The courgain maritime is a old neighbourhood of calais, typical fishermen area,
Very dynamic in the past and still popular. You can find nice local fishes and traditional French food restaurants, kiosks where you can buy every morning, fresh fishes ,mussels and crabs , a typical traditional bistrot and a wonderful view on the marina and ferry port.
if you visit Calais don’t pass this area which is really nice. I use to walk around with my dog and you could really spend hours to look at the see and the port life always moving and offering so nice pictures.
