Explore the tranquillity of the Saint-Omer marshes

Come and lose yourself in the peace and tranquillity of the Saint-Omer marshes.

There are countless ways to enjoy the many delights that this UNESCO Biosphere Reserve has to offer. This is a great day outing with the family or friends. Cruise along the waterways, walk among nature, sample the culinary delights of this fertile land or just sit back and soak up the atmosphere.

Discover the magical marshes

Come spend the day at this eco-friendly attraction, located in the idyllic setting of Clairmarais in the heart of the marshes, right next to the Romelaëre nature reserve.

Covering more than 3,700 hectares of manmade marshland crisscrossed by 700 km of waterways, this nature haven was created in the Middle Ages.

The fertile farmland produces a cornucopia of local produce and provides an insight into a unique way of living that has endured for centuries.

It’s an area ripe for exploration, so go walking or cycling, hire a boat or just sit with a cocktail and enjoy the serenity.

Make lasting memories 

For a truly authentic experience, take a trip on a wooden bacôve – the traditional market gardener’s boat that is still carved in the region today.

Join a night cruise and be serenaded by a chorus of owls and bats or set sail at dawn and see the stunning spectrum of colours and reed silhouettes as the sun rises through the mist. Alternatively, treat yourself to a dining cruise so you can sit back and feast while exploring the area.

You’re never too old for a good tale, so why not join renowned storyteller Christine Charpentier on a storytelling cruise? Be enthralled as she introduces you to the secrets of the marshes through the tales of fictional adventurer and hero Rocambole.

Shop in an idyllic setting  

Food shopping will never feel the same again after you’ve stopped off at a farmers’ market with a difference on the side of the marshes. Stock up on the freshest of fruit and vegetables grown right on the banks in the incredibly fertile soil.

Visit the ISNOR ‘village’, where market gardeners, local producers and regional artisans also offer a delicious assortment of cheeses, jams, terrines, beers, bread and pies.

Shop for a special souvenir from the marsh. Choose a figurine of a local bird or animal or pick up a postcard or two. You’ll be spoilt for choice with the wide range of books, maps and guides, wooden games, toys and organic soaps on offer.

Sample delicious French cuisine 

The fresh marsh air is bound to give you an appetite, so enjoy some traditional Flemish cuisine at La Terrasse Restaurant or the Terrasse Bar. Why not try the famous house speciality: suckling pig, cooked for eight hours in a wood-fired oven?
