Bus from Trpanj to Orebic
During the off season months buses were less frequent while in season, June to September, when ferry schedules are more frequent, buses run to match the same frequency as ferries.
Basically, what you have to keep on your mind is that
each ferry that arrives or departs from Ploce or Trpanj is met by bus from/to Orebic. (Update: Unfortunately, this is not the case any more)
The journey lasts for about 40 minutes and leads partly through inland bit of the Peninsula and then downhill along the coast to Orebic, offering some nice views over Peljesac Channel and Archipelago. This is a really nice bus ride especially in autumn when all vineyards are in yellow/reddish colours. On its way bus will stop at any point along the route if there is a passenger waiting. So, if you are staying in Dingac, Postup or similar , you will be able to catch this bus. Have a look at the schedule bellow:
