A fantastic place to visit as a backpacker, Europe offers a wide array of different cultures and scenery inside a small area.
It contains such great party spots as the Greek Islands, Amsterdam and Prague.
There's also a great deal of impressive architecture and historically significant places like The Colosseum in Rome, the Acropolis in Athens, the still blackened Dresden, and the various concentration camps such as Auschwitz in Poland and Dachau in Germany.
And no writeup on Europe would be complete without reference to Vatican City, which houses the world's largest church in its smallest country. A walk through the Vatican Museum to the Sistine Chapel could take up the best part of a day. It's that impressive.
Oh, and visit Prague and see it by morning. It will take your breath away.
