"Herbst" (Fall) in Germany is an ideal time to visit, happily caught between the high prices of summer and the crowds of Christmas. The weather is usually still warm and the days are long and filled with light. While there are plenty of people visiting Germany during this month, the crowds have gone down and the peak costs of accommodations and attractions are lowering.
On top of that, some of Germany's top events are in September. The world-famous Oktoberfest actually begins in late September and continues for two weeks through early October. This is also the perfect time to enjoy a long drive on one of Germany's scenic roads, either to events like the largest pumpkin festival in Germany or to one of the country's many wine festivals or just to enjoy the spectacular changing of the leaves.
