If you are flying to Split, you will be arriving at Split airport, situated between Split and Trogir. It takes approximately 30 to 40 minutes to get to Split’s ferry port from the airport. You can take the official Croatia Airlines bus, or one of the many private mini buses or taxis.
From Split you can take a catamaran (one-hour journey) that will bring you straight to the town of Hvar directly in front of CARPE DIEM BAR, or the ferry boat (two-hour journey) that will bring you to the island Hvar, arriving at Stari Grad town. It takes about 20 to 30 minutes from Stari Grad to the town of Hvar. Both, the catamarans and ferries, leave Split port several times a day.
Jadrolinija is the main Croatian ferry service, and on their website - www.jadrolinija.hr - you can find details regarding routes and times.
