Start from Esplanade Simone Veil, between Place Gambetta and the tourist office, near the Port of Vannes. Park in the underground car park at the port (paying).
(S/E) When you leave the car park, head towards the port. Then follow Quai Éric Tabarly on your left and walk along the port on your right. At the end, turn right until you reach the traffic lights. Then turn left and cross Place Gambetta in two stages.
(1) Continue straight ahead between two bar-restaurants and pass under the Porte Saint-Vincent. Continue straight ahead and go up the street of the same name. Turn left around the Place du Poids Public and continue for a few metres along Rue Saint-Vincent.
Turn right onto Rue Porte Poterne and walk along the market hall on your left. At the corner (old gate opposite), turn left into an alley and walk along a car park. Climb the steps on the right at the foot of the Tour du Connétable to enjoy a bird's eye view of the rampart gardens.
Continue along the alley and cross Place Lucien Laroche. Continue along Rue de la Monnaie, then turn into the first street on the left, Rue des Orfèvres. Cross Place Valencia and you will come to a half-timbered house with a sign saying "Vannes et sa femme" on the corner of Rue Noé.

Retrace your steps and, at the intersection, continue straight ahead on Rue Saint-Salomon. Cross Place Henri IV diagonally to the right towards the cathedral.
(3) Continue to the entrance of the cathedral (open during the day). Retrace your steps.
(3) Continue straight ahead towards a large building (early 20th century?) with a distinctive turret and immediately turn right onto Rue des Chanoines. Walk along the cathedral on your right and take the first left, Rue Auguste Brizeux. Continue to the Porte du Bourreau and retrace your steps.
