Hard Backpack

I am 20 and I was wondering is it difficult to backpack through Europe, I would be next summer or in the next few years because of all the things you have to do and the country you want to visit?

Many people do every year. In fact, you do not need to do stuff much at all, it is very important to travel light and only two or three changes of clothes and a couple of hot spots and clothing so you can layer if it's cold . Whatever your need, you can buy in Europe.

Obtain a copy of Lonely Planet Europe on a "Shoestring and work on a route of travel before all kinds, so you do not waste time a money back for seeing.

Many people do! There are great train, airplane and bus services to most European and most tourist attractions are few English speakers (the only problem I really had in Paris and Zargreb but my very limited French and German (which is widely spoken in Croatia) helped a little apart .... than English, I spoke. If at first you do not succeed in finding the next person who can speak English ... just keep trying.
Do you research first ... then you know what places are valid see and not really worth ...... also make a plan, then ask again to see what people say, for example, if his time eough, you missed the scene etc. .... I have some for flexibilitiy also add or modify your plan you will find a place that you want to stay longer.
Watch your costs ... accommodation and travel will be more, food costs and the entry will be the rest. Try not to buy too many memories of the way as they fill your bag or cost a bomb to send. Look at the shared accommodation in hostels for the cheapest accommodation such www.hostels.com, etc. www.hostelbookers.com to see what it will cost at each location ... some places will cost much more than others for example, Venice and Florence were expensive.
www.skyscanner.net try for some options on the flights you can get very cheap rates at times to Europe and perhaps even cheaper than the bus or train ... uh I think his eurolines.com is .. Bus or minus a few options in many places.
If you do it slowly over the next 2 years ... Online always looking for tickets to get there and if you have ideas for overhead and know a bargin when you see, when times are less expensive to fly and where even fly ... . gradually learn about some places you want to go to ... get a good travel book and read it or get it from the library to read.

It is quite possible. Thousands do it every year. I would start by reducing the number of countries you want to visit. Then, purchase a guide, like Fodors or Lonely Planet.

The only difficulty is the language barrier, especially outside major cities. So, choose a small number of countries and get a book of phrases for each language.
