Don't waste your money on a taxi or rental car when public transportation is just around every corner. In England, Germany, Italy, France, etc. there is the tube, u-bahn, metro, and/or métro. These public transportation trains can be compared to the D.C. metro or the NY subway system.

Not only are there several stations spread through every part of major cities, but they are almost always conveniently located next to major tourist destinations. In London to see the Queen? Try the Green Park station next to Buckingham Palace. In Rome and in need of a stroll through the Colosseum? Try the Colosseo, Line B of the Rome Metro. A traveler can navigate from the airport to the entrance of Oktoberfest in Munich, Germany or navigate through Paris, France to the Eiffel Tower, Notre Dame, and the Louvre using their Métro lines.

These trains all provide visitor rail passes, resident passes, day passes, or one way tickets. They are flexible to a traveler's stay, and most are open from early morning to later at night. Countries are making it more convenient to commute this way, and these commute methods are quick and efficient. Check out their individual sites for ticket pricing, and consider this as a primary travel method when overseas.

So next time you're abroad, if you need to get somewhere a little too far for a walk or want to arrive quickly, take the trains.
