(S/E) Take Rue Demarle Fetel on the left. Pass between the war memorial (on the right) and the Arsenal bridge (on the left) and walk slightly uphill on Rue des Remparts (pink markings). Follow the rampart walk. Enjoy the view of the harbour, the guardhouse, the channel and the moat of the fortified town. Go down the paved path.
(1) Turn left and follow Boulevard Lamartine for about 200 metres, then turn left to walk along the River Aa. Follow the channel dyke to the lighthouse for about 1.8 kilometres.
(2) Facing the beach, turn right onto the dyke, walk past the beach huts and then along the dune ridge for about 1 km. Move away from the dune if you prefer to walk on hard sand.
(3) Turn right across the dune to head inland (at the wooden post painted red on the upper half). Be careful not to miss this change of direction.
Continue straight ahead to pass between the campsite (on your right) and soon the farm (on your left). After the farm, the tarmac road turns right and then soon turns left. You will arrive at the road that leads to the town centre.
(4) Cross the road to enter the "Parc du Polder". Follow the path that crosses the meadow with the rugby field on your left. Follow this path for about 800 m along the ditch (on your right). You will arrive near the tennis courts (on your right) and the fire station (a little further on your right).
(5) Cross Route des Enrochements using the pedestrian crossing a few metres to the right and continue into Parc du Polder. Follow the stream (on your left) and continue straight ahead for about 1 km on Chemin du Nord Blanc.
(6) Facing the ditch, turn right and continue for about 350 m until you reach the main road (roundabout). Cross it and take the footbridge opposite, then the path straight ahead that crosses the small wood. Cross the small pond and keep to the left to reach the road.
Cross at the pedestrian crossing. Keep left along the road, then turn right immediately. As you pass, admire the Porte aux Boules on your right, one of the gates leading into the citadel.
(7) Enter the allotment gardens and go around the town via the Pépinière. After the gardens, continue straight ahead through the undergrowth, following a fitness trail.
(8) At the three-way junction, turn right to reach and cross the old locks. Take the bridge on the right (Rue de Calais), then turn left onto Rue Demarle Fetel to reach the museum car park (S/E).
