Honfleur is superb for aimless ambling, especially if you have a walking map from the tourist office. One option is to head north from the Lieutenance along quai des Passagers to Jetée de l’Ouest (Western Jetty), which forms the west side of the Avant Port, out to the broad mouth of the Seine. Possible stops include the Jardin des Personnalités, a park featuring figures from Honfleur history; the beach; and Naturospace, a lush greenhouse filled with free-flying tropical butterflies and birds that’s situated 500m northwest of the Lieutenance.
The tourist office also has audioguides (€5; in English, French and German) for a 1½-hour walking tour of the town.
Le Pass Musées (adult €13) gets you into all four municipal museums for less than the price of two.
