Gellert Hill and the Citadella is a must see thing indeed, but the thing I like the most about it is the view the Hill offers! It’s just so high above the city, offering a great overview of the structure of Budapest. From the Statue of Liberty (in front of the Citadella) you can also see, the Buda side and the southern part of Pest including the Csepel Island. From the side facing the Danube, all the Pest side, the buildings along the Danubeside, like e.g. the Parliament and also the Buda Castle is visible. Simply amazing! 🙂
Directions: On the top of Gellert Hill in Buda. Access by bus #27 from Moricz Zs. korter. Get off at Busulo Juhasz (Citadella) stop and walk uphill. Cars not allowed beyond a certain point.
