There are a number of ferry routes to travel the 40 miles (65 km) between two of Croatia's most popular islands, Korčula and Mljet. Whether you have a car or not, there are two ferry options for traveling between the two islands. Remember, however, that direct travel between Korčula and Mljet is only possible during peak travel months, or mid-April to October.
Travel by ferry is hands-off and a relatively inexpensive mode of transportation that provides scenic views. During the off-season or to transfer a car from Korčula to Mljet, the route also includes a stop at the mainland peninsula that is connected to Ston, another popular coastal city.
By Private Transfer
Duration: 30 minutes or more
The most convenient and efficient option to travel by private transfer can also be highly personalized. Travelers can book a simple transfer with or without a return ride for a day trip. Alternatively, highering a private boat transfer also provides the opportunity to do some island or beach hopping with a local guide who can provide further insight.
Duration: 30 minutes to 3 hours
Kapetan Luka and Krilo ferries run between Korčula and Mljet run from mid-April to October, peak tourism months. The fast boat is reasonably priced and among the most efficient methods of reaching Mljet in just half an hour. There is, however, only one daily departure. This option is also only suited to foot passengers. Travelers that wish to take a car to Mljet too must take the longer, indirect route, which is also the only route during the off-season.
Jardolinija also operates a ferry, though it requires an extra hour and a half travel time. This route operates year-round with four or five daily departures contingent on the season. This is the route to take if a car must be transferred as well. In this case, take the ferry from Korčula to Orebić then drive to Trstanik. From Trstanik, take the ferry to Polače. The entire journey requires roughly two and a half hours
If visiting Ston as well, it is possible to drive from Orbeić to Ston. From Ston, there is a closer ferry terminal in Prapratno which transfers to the city of Sobra on Mljet. This route requires roughly three hours, but allows for more leisurely travel with time on the mainland for additional sightseeing.
