Visit charming Miltenberg on a German river cruise and you’ll quickly understand why this quaint Bavarian town is affectionately known as the ‘Pearl of the River Main’. Revered for retaining its scenic beauty and romantic historical charm, Miltenberg is one of only a few German towns not to have been extensively rebuilt after the Second World War, so many of the wonderfully well-preserved streets and structures here are as they were several centuries ago.
