Germany attracts tourists both because of its array of attractions and because it’s so easy to travel there. The scenery, architecture, and history could occupy you for a month or more, and with the well-developed public transportation systems and prevalence of English, you won’t have trouble getting around. The only thing necessary for your trip to go smoothly is to pack all the essentials, including the necessary electronic devices and a US to Germany power adapter.
The summer months get the most tourists in Germany, which means more crowds and higher prices, but it’s also the rainiest time of year. Spring and fall are less busy and less rainy, so visiting then instead is a win-win. Germany is also an incredibly popular Christmas destination, so things get busy again in December – but it’s a magical time of year to be there.
Tourism in Germany peaks around Oktoberfest as well, in late-September and early-October. Unless you’re a beer enthusiast, you’ll want to steer clear of Munich then (and if you don’t book far in advance, you probably won’t have a choice).
