Anyway, remembering my visit to the Lake District inspired me to ponder if Hungary has a place of similar beauty. Yes, Hungary does have a beautiful "lake district" of its own in the form of Lake Balaton, but the landscape there is nothing like the north of England. After much thought, I came to the conclusion that Visegrad and the so-called "Danube Bend" about 45 kilometers north of Budapest is the closest Hungary comes to the Lake District in terms of landscape and scenery.
True, there's no lake, and Visegrad is not completely enveloped in a National Park, but the Danube is rather wide, and as it bends south it does give the illusion of being a lake. More importantly, the Danube Bend is home to many splendid hills and upland swells.
Not quite the Lake District, but still beautiful in its own right.
