There are a number of ferry routes to Korčula, a journey of about 75 miles (roughly 120 km) from either Split or Dubrovnik. Regardless of your starting point, you'll transfer in Split or Dubrovnik unless a private charter boat is hired.
Travel by ferry is a relatively inexpensive mode of transportation that provides scenic views. Though travel from Dubrovnik and Split is possible year-round, the options change depending on the tourism season. Typically, there are the most options and departures between mid-April and October during peak tourism.
Duration: 30 minutes to 3 hours
Kapetan Luka and Jadrolinija ferries run between both Split and Dubrovnik and Korčula. The catamaran is reasonably priced and among the most efficient methods of reaching Korćula in just under two hours from Dubrovnik. Jadrolinija sails in the morning while Kapetan Luka sets off to Korčula in the afternoon. A third option is to take G&V Line from Dubrovnik to Korčula, which takes two and a half hours but stops on Mljet island as well.
Kapetan Luka sails a daily catamaran from Split to Korčula as well, requiring roughly two and a half hours. Jadrolinija also runs a catamaran, though it is nearly an hour longer due to two additional stops at Brac and Hvar Town.
If planning to take a car to Korčula as well, the primary option is to drive to Orebic and catch the car ferry. This ferry is only a half-hour journey and leaves often throughout the day. A car is not necessary on Korčula as the two main towns are quite walkable and there is a bus that runs between the two multiple times per day.
By Private Transfer
Duration: 2 hours, more with stops
Choosing to hire a private boat transfer allows for complete control over travel–including how long it will take to reach Korčula. Travel by private boat allows for a local guide to arrange stops at other islands such as Mljet as well as other towns, beaches or coves on Korčula's coast.
