Family tour in the heart of the fortifications of Gravelines, a town on the water, you set off to discover a military architecture located between the medieval fortress and the modern-day citadel with geometrically profiled bastions.
To depart by boat, head to the specially designed pontoon where you'll cast off for a tour that follows the moat path. You'll be able to experience Gravelines in a completely unique way, whether with family or friends.
