I have visited almost all Dacian fortresses in 2007. Almost all the places are located in the remote, mountaineous area (you should have a good local map to get there or at least have enough luck to find a person that show you the right direction, 4 wd car is also recommended). The places itself are extremely worth visiting as they are the only surviving examples of once powerful culture of pre-Roman Dacian state. The most important monument is Sarmisegetuza Regia, remnants of Dacian capital with its sanctuaries, walls and other buildings. It is one of Romanian touristic "must".
