Bonn, Germany's former capital, is a small place and everything is accessible in only a few minutes. Locals love to ride their bikes and the city offers an amazing network of parks that seem to be connected. You can ride alongside the Rhein river and enjoy the breeze. This is the perfect spot for people who love jogging, or simply sitting on a bench to read. When the weather is nice, street food and ice cream (or a cold beer) would make your day perfect.
