For those with serious intentions to “do” Dubrovnik, the Dubrovnik Card, available from the tourist office (see p.409), is a sound investment. Costing 150Kn for one day, 200Kn for three days or 250Kn for one week, the card allows free rides on municipal buses, free entrance to the city walls, and free entrance to eight museums and galleries: the Cultural and Historical Museum, the Maritime History Museum, the Ethnographic Museum, the Archeological Exhibition in Revelin Fortress, the Natural History Museum, the Marin Držić House, the Dubrovnik Art Gallery, the Dulčić-Masle-Pulitika Gallery and the Pulitika Atelier. Otherwise entrance to these eight museums and galleries is by combined museum ticket, which costs 100Kn for adults, 25Kn for students and children, and is purchased from the museums themselves. This ticket is not valid for the city walls or transport. Neither the card nor combined ticket covers the Aquarium, or a number of independent museums and galleries such as War Photo Limited and the historical monastery collections.
