Dubrovnik public transport is very well organized and operates a network of over 10 reliable bus routes. Buses usually start running at 5 a.m. and stops around midnight, even though there are night lines as well. Libertas Dubrovnik is the official company that operates the routes connecting all urban and suburban areas of Dubrovnik. Bus tickets can be purchased directly from the driver or at kiosks of Libertas or TISAK that can be found almost at every bus station. If you buy a ticket directly from the driver, the price is 15 Croatian Kuna, but if you buy it at the kiosk the price is 12 Croatian Kuna and it is possible to pay only in cash. The ticket is valid 59 minutes from the validation / stamping and can be used in all directions. There is also a daily ticket (30 Croatian Kuna) which lasts 24 hours from the first stamping and there is no restriction in the number of trips. Children under 6 years accompanied by an adult do not have to pay for the public transport. If you don't have a ticket or is not properly stamped, you will immediately have to pay a fine the amount of 100 kn to a bus conductor.
