Ploce-Trpanj Car Ferry
The "Losinjanka" may handle this route
The Ploce-Trpanj car ferry takes one hour and connects Ploce, on the mainland with Trpanj on the Peljesac peninsula. You mean you don't want to stay in Trpanj? Fine. Drive a few kilometres to Orebic where you can take the Orebic-Domince ferry to Korcula Island. Now that the Peljesac Bridge is open, most visitors will have little reason to use this ferry. Driving across the bridge is faster and also free.
The Ploce-Trpanj car ferry shuttle is run by Jadrolinija.You can buy tickets online at the Jadrolinija website, at any Jadrolinija office or go to the port at least 1/2 hour in advance, buy your ticket at a stall and put your car in the waiting line. Buying tickets in advance does not mean you don't have to wait in line as the ticket is not a reservation.
