Hi friend, I just saw your request on going along the Danube from Budapest to the Black Sea. I did the whole trip along the Danube to the Ukrainian border an to Sulima (where the Danube joins the Black Sea) and went on to Constanta and Varna. Unfortunately, I actually have only very weak internet conection, but from tomorrow evening on, I will be back home and can give you any information you like, if you ask me for. I could also send you my report on the whole trip, but it is in german. You cab find all my pictures from the trip on http://picasaweb.google.de/pemanz/Donau2009
The area is just great to discover and worth going there !

Greetings
Peter
