Tips for European travel - Transportation Tips
For traveling around Europe between destinations you have several options: short flights, trains or car rental. Flying is the quickest way to get from one country to another and is sometimes cheaper than other options, too. It does limit you to major cities, however, and often airports are located outside the major metropolitan area, meaning you will have to find additional transport to and from the airport.
The rail network in Europe is extensive and easily navigated but can be expensive. For travel around the continent, look into a Eurail pass to save some money, and be sure to book tickets well in advance to avoid premium prices. Eurail passes are available to non-European Union residents for unlimited train travel in one country, within a specific European zone, or for the whole of Europe and are cheaper than multiple individual tickets. They are the equivalent of the InterRail pass available to EU residents.
If you are going to rent a car and drive in Europe, know that gas is considerably more expensive than in the United States and that you will probably need to be able to drive a stick shift. You will need up-to-date, detailed maps of every place you want to drive in order to successfully navigate the roads. Do a little research into local traffic laws to avoid any unwitting violations, and remember to bring your driver's license.
