Hi there I know where First you can go to Jogja, then proceed to Magelang by Bus it takes approximately 2 hours, from Magelang you can stop here a while to visit magnificent Borobudur temple one of the 7 wonder, then you can take Bus again to Wonosobo it also takes about 2 hours. Okay from Wonosobo you still need to take minibus to Dieng for another 1 hour, that I s the itinerary but I am not sure about the fare since last time I went was 2008, but it is relatively cheap

I will take note as well, thanks

Thanks for the guide info
