In the 20th century, Berlin figured in two world wars and was a divided city, East and West Berlin, for nearly thirty years. Look around town for the "Berlin bears" - everywhere you turn, there's another colorful bear painted with fanciful designs. Kids can climb on the Berlin bears all they want.
Tip: Berlin has an extensive and convenient subway (U-bahn) and above-ground train system (S-bahn). Get a "Small Group" ticket (up to five persons) for the day, or a Welcome Card 2 or 3 days pass, and go anywhere within Berlin city.
