Prapratno-Sobra
Because of the rarity of the ferries from Dubrovnik to Mljet island, for me the best option was to catch it in Prapratno which is operated by the company Jadrolinija. Between June and September there is a frequent service (7:00, 10:15, 13:00, 17:00 and 23:30). The journey takes about three quarters of an hour, during which time you can enjoy a wonderful crossing.
