Ploce has a population of approximately 6,500 inhabitants. It is a notable seaport. The most important feature of town is his natural position through the valley of the Neretva River, which connects the central areas of neighboring Bosnia and Herzegovina with the Adriatic Sea. Town is situated in approximately half of distance between Split and Dubrovnik on the part of the road traffic along the Adriatic coast.
Near the town are Bacina Lakes, along the branches of the mountain of Biokovo.
There no longer is a train between Ploce in Croatia and Capljina in Bosnia and Herzegovina. Inside BiH, from Caplinja to Sarajevo there are trains running. For valid timetable look at http://www.hznet.hr/timetable
Buses from Dubrovnik to Ploče run regularly from Dubrovnik (2-2½ hr). Every hour, day & night, so you should have no problem finding one. Some info is here  [dead link]. To Split you need some two hours.
There are at least four daily ferries, more during the summer season, from Trpanj on the Pelješac peninsula. The ferries are operated by Jadronlinija with a journey time of one hour. 1 Ploče port is located at King Tomislov square 26 (Trg kralja Tomislava 26).
- This commercial port is a great jumping-off point for tours to the old city of Mostar in Bosnia.
Hotels are limited but there exists a number of smaller bed and breakfasts scattered in the town and in nearby villages.
