(S/E) Return to the car park entrance and turn right onto Avenue de la Plage. At the end of the field, just before the roundabout, turn right onto the cycle path. Go through the Porte Thoiras and then the Porte de la Flotte and turn left in front of the prison entrance, following the pedestrian crossing. On the pavement opposite, turn left towards a large cypress tree.
(1) Turn right before the tree to go behind the powder magazine, following the gravel path. Reach the Poudrière car park and turn left to cross it. Continue straight ahead on Rue du Rempart, pass the entrance to the campsite and follow the street as it curves to the right.
Leave Rue du Rempart on your left and continue straight on Rue du Père Ignace until you reach Place de la République. Leave Rue du Général Lapasset opposite and head towards the notary's office, slightly to the left opposite.
Follow Rue Bailly d'Aulan (cobbled), which starts at the corner of the office, and continue to Saint-Martin Church (you can visit the bell tower observatory for €2).

First turn right/left and continue along Rue Aristide Briand until you reach Porte des Campani, which you must cross. After crossing the moat, look for a drinking trough with a well on your right in a bend.
(3) Cross the D20 at the pedestrian crossing and turn right onto the path running parallel to the road.
After the Bastion de Bourbon (park and information panel on the left), take the paved path. At the car park, continue straight ahead on the path. At the end, turn left onto the grass to go around a mound and reach the Bastion de la Mer.
(4) Continue to the right, following the sea to the end of the harbour. At the anchor on the ground, turn right to walk along the harbour to the Quai de la Poithevinière. Turn left in front of the restaurants and shops to continue along the harbour. Continue along the Quai Job Foran and the Quai Georges Clémenceau towards the lighthouse.
