I visited this WHS in June 2014. I ventured on an early morning drive in the Alta Murgia National Park. The drive past rolling hills with red poppies, cherry trees and olive trees was already a good start but standing alone on a promontory in the middle of the park was the Castel del Monte. There is a huge parking lot about 800 metres from it where I left my car and with the 5 euro ticket I got a return shuttle bus ride to the WHS. The castle is in a very good state and it really gleams in sunny weather. Its octagonal plan is really unique and several information boards inside the empty castle give you detailed info on the history, architecture and significance of this site. The courtyard is the main highlight inside the castle but other than that the 5 euro entrance fee doesn't offer much. The panoramic views from the castle are not to be missed and I think that opening the castle's terrace/roof in the future would make a much more interesting visit. I finished off my visit with a hearty snack near Andria - Focaccia Bread with Burratina ... bliss!
