The local tourist office can organise walking tours of the old city which take in all the main sights. Tourist agency Atlas (tel: (020) 442 900; website: www.atlas.hr) has offices in Pile, Grad and Gruž and offers one-day tours that include a bus trip to a panoramic viewing point overlooking the old city followed by a guided walking tour. It also organises evening cruises around the old city accompanied by wine and music. During the main season (June-September), myriad small boats leave from the old port for the islands of Koločep, Lopud and Šipan, as well as the island of Lokrum, which lingers just across the water from the old city. Nova International (website: www.nova-dubrovnik.com) operates fast services to the Elaphite Islands and between the old port, Lapad and Gruž.
