Airport buses run to the central bus station/train station and the Old Town, from Zadar airport terminal. They depart in conjunction with arriving flights, see airport bus schedule for details, and therefore they will run more frequently during weekdays than weekends, as more flights are arriving at the airport. The buses are clean, comfortable and efficient, costs 25 kuna, and there are no baggage fees.
Taxis are always available at airport.Cost to old town is approximately 150 kuna.see taxi prices
Croatia Bus: Several buses daily, stopping in Zadar on the way between Zagreb, Split and Dubrovnik.
To get from the inter-city bus station (and train station) into the center of Zadar, or the old town, a local bus stop is located on the main road just outside the station. Bus (costs 10 Kuna) number 2 or 4 will take you directly there, the journey is only five minutes. Taxis (costs 20-40 Kuna, ask first) will also be waiting, however, be advised they have a reputation for ripping off tourists, charging much more than the officially posted rate (as much as five times higher). Do the world a favor and catch public transport or walk - walking will take you about 10-20 minutes dependent upon your location in the Old Town.
The train station is located at the intersection of Ulica Ante Starčevića and Ulica Ante Starčevića (lat/long 44.106647,15.241961), right next to the inter-city bus station.
A few slow trains a day run to Knin and connect into trains for Zagreb (5,5 hours or 8,5 with overnight trains) and Split (3.5 hr). Virtually nobody uses this train to get to these cities. Train to Knin is one carriage long with no A/C and can be quite uncomfortable, however the scenery is beautiful and will leave you in wonder at the numerous stations which appear to be in the middle of nowhere. Check the online timetable at HŽ Putnički prijevoz (2013-06-09, searching for routes only works in the Croatian language version of the site, not the English).
Jadrolinja, Large ferries run every few days up and down the coast between Dubrovnik and Rijeka, stopping off at ports (including Zadar) and islands on the way. They also run almost daily ferries in summer to and from Ancona in Italy.
Note that many boats now arrive and depart from the "new" ferry terminal, around 5kms from the old town. A public bus is available, inquire at the Jadrolinja office in the old town. Taxi fare was quoted at 80 Kuna (tourist prices).
The Old Town is easy enough to get around on foot. To reach the bus/train stations you can walk or catch one of the frequent local buses (bus 2 or 4 will take you there from the Old Town).
Buses in Zadar are relatively new and well maintained, and you will be able to catch a bus to any part of the city from the main hub in the city called Mala Pošta (Little Post Office); ask any local where this is and they can direct you to it. A bus ticket in one direction costs 10 Kuna (cca. US$1.75) while a two way ticket costs 16 Kuna (cca. US$2.80). However, two way tickets are only available for purchase at newspaper stands, although they are easy to find. One way tickets are available for purchase upon entering any bus. Buses are run by Liburnija; an online timetable is available.
Be advised that bus services cease just after midnight during the summer, so if you plan to get back to a hotel that isn't close to the city center after that time, you might have to walk or catch a taxi. Do not attempt to board a bus without a ticket, without purchasing a ticket or avoiding stamping a bus ticket. Bus drivers in Zadar are notoriously militant about enforcing payment, and you could get into trouble.
Taxis - a trip of up to 5 kilometers (enough to get almost anywhere within the city) may cost up to 80 Kunas, as the taxi drivers have a habit of overcharging tourists. Inquire first, as it will be almost impossible to find a taxi for the advertised price of 20-40 Kunas (circa US$3.5-7). Ask before you get in the cab - there should be a printed price list, although many drivers will not obey this list. There are taxis waiting on both sides of the bridge in the Old Town, and around the bus/train stations.
Walk around the atmospheric streets of the old town, located on the peninsula. There are 34 old churches situated on the peninsula, and all of them with a very rich history. The oldest is St. Simeon (Sv. Šime).
St. Donat's church. One of the best preserved pre-Romanesque buildings in the world. It is pretty difficult to miss, as it has become the most recognizable symbol of Zadar. The church is no longer in use for religious ceremonies, and today is a museum. It also holds a series of classical music concerts every summer.edit
Roman Forum. Well preserved remains of a Roman Forum. This is a common place for locals to stroll, sit down amongst the ruins and enjoy a nice summer day.edit
The cathedral of St. Anastasia (Zadar Cathedral). The city's cathedral with an impressive organ that was nearly destroyed in the last war.edit
St. Mary's church. Houses a museum of antique religious relics and artifacts.edit
St. Simeon's church (Sv. Šime). Houses the silver reliquary of the saint, one of Zadar's main sights.edit
University of Zadar. Originally founded by Dominican monks in 1396, it is the oldest university in Croatia, and one of the oldest universities in Europe.edit
Archaeological Museum (Arheološki muzej), . Covering the period from prehistoric times to Middle ages, the collections of this museum testify to Zadar's long and rich history. Romanesque stone carvings are of particular interest.(44.11555,15.225)edit
Sea Organ (Morske orgulje). This man-made organ on Zadar's Riva works with the motion of the waves and 35 pipes to create a musical soundscape. A favorite for locals and tourists alike, and accompanied by a light display that creates visualizations of the sounds being produced by the organ.edit
There are plenty of small bars close to each other in the narrow streets of the Old Town, for example along Kovačka ulica.
As drinking in public is legal, it's also common to buy something in the store and go to the sea side, for example to the sea organ.
