All year round, from the Maison du Marais, at the foot of the city of Saint-Omer, discover the Marais Sauvage aboard our traditional boats!

An hour-long walk with commentary guides you through fauna and flora, nature and city, for a complete understanding of this highly symbolic place on the Audomarois. In our interactive space, take a trip through the testimonials of the Marais people, from past to present day, then dive into our aquatic space amid various species from beneath the marsh. Careful though! Some are more docile than others! But that’s not all! Are you brave enough to follow Lord Greenmarsh, Grand Explorer of the Marais, on his new expeditions…?
