May in Germany provides visitors with the opportunity to enjoy good weather, a myriad of spring and summer festivals and a last chance to visit before the high tourist season starts in June. The Hamburg Harbor birthday, with its parade of tall ships and massive festival takes place every year the second weekend of May and the first Rhine in Flames event takes place in Bonn, to name but a few of the things that take place in May. Airfares are still low so whether you are traveling north to Hamburg or Berlin or south to Munich or Stuttgart, you will find plenty to do in May.
