Due to its proximity to the mainland and Split in particular, Brac is one of the most accessible islands in the Croatian Adriatic. There are ferry routes to several of its major towns. A very frequent car ferry route (journey time: 50 minutes) operates from Split to Supetar on the north of the island with an even higher frequency during summer. The year-round daily catamaran service from Split to Bol, on the south side of the island, takes 55 minutes. This catamaran then sails on to Jelsa on the island of Hvar.
In summer, a once-a-week catamaran runs from Split to Milna on western Brac, with a journey time of 30 minutes. From early June to mid October, there is also a catamaran service from Split to Bol that then travels on to Hvar, Korcula and Dubrovnik.
Milna is located on the western part of the island Brac, 18 kilometers from Supetar. It is famous by its marvellous bay, in which the ships of the emperor Diokletian have found a secure harbour in the time of the building of his palace in Split.
