Bus schedule from Dubrovnik to Sarajevo?

I should also add that this question is part of a larger effort to feasibly/economically connect the southern Dalmatian Coast with Sofia, Bulgaria...any general advice would be MUCH appreciated!

I just did this trip last sept/oct 2011 from dubrovnik there are few daily buses to Mostar in Bosnia Herzogovina,i suggest you go to the dubrovnik bus station which is further away from the old town dubrovnik area you can get a local bus take you there from Pile gate buy a ticket to mostar worth visiting you wont regret 2 days is enough and from there bus a train ticket from the train station which is actually near the bus station right next door mostar to sarajevo is a wonderful scenic ride you will enjoy the train ride prices are so cheap the train ride was less than 10 i think 5 bosnian cheaper than bus bus was almost 15 bosnain 2 bosnian is 1 euro i think suggest kandilj pansion in sarajevo incase you need place to stay they will pick you up at train station and in mostar stay at cardak pansion Mr Nejad will pick you up at bus station in mostar and drop you back when you are going to sarajevo this was one of my wonderful experience in Bosnia and Croatia.
Hope this helps

You may want to have a look around the following website that we found very useful when traveling to Croatia a few years ago: www.croatiatraveller.com Under the Transport section you will find a link to the Buses page where you can find information on some of the local bus companies/stations. Upon arrival in Dubrovnik you should probably get to the bus station to confirm the schedule and buy your tickets for travel a few days later. As for the Dubrovnik - Sofia connection, I can't really help you but you may want to take a look at this thread from the Lonely Planet Thorn Tree forum: http://www.lonelyplanet.com/thorntree/thread.jspa?threadID=2015292 Good luck!
