If you're asking yourself how much does it cost to travel across Europe, then in a sense you may as well be asking how blue the sky is. The truth of the matter is, planning to travel across Europe can be done on any budget, and often is. If your plan is to travel across Europe in ten days, chances are you will need to spend a certain amount of your cash on preserving your sanity and splashing out on a place to crash that has a shower (from time to time). Also, if your time is limited, you may need to spend extra on getting to your list of destinations in the quickest manner possible (which is often not the cheapest). If, instead, you are thinking of working your way across Europe, then the cost will have significantly less of an impact on your financial status.
The largest expense in considering how much it will cost to travel across Europe is usually the flight. Bring down the prices of your flights by offering to fly standby, or by booking last minute. Depending on the airline, volunteering to be bumped from an overbooked flight can get you a free night and a meal at a nice hotel. Often, if you can be organized with your finances up to a year ahead of time, free airline tickets can be purchased using a frequent flyer program. For young adults aged up to 26, discounted rates for rail or coach travel are available by procuring for yourself an international student card (applications available at your university or local post office). Combining the cost of your travel by purchasing an InterRail pass can help to plan your expenses, but often even those prices can send you into anaphylactic shock. Opt instead to break your journey into a combination of rail, coach, and air travel.
Spending a "year out" or "Gap Year" is a common thing in the EU that many young people take before beginning university, or after university before taking on a career. Even if you are older or further along in your career, you may find that your skills can be just as useful to a foreign company as they are at home. You may be surprised at how many opportunities you may find by searching for a job with these phrases in mind, or how open your current employer may be to find that you wish to pursue this interest before returning to work with a fresh frame of mind and broadened experience. The truth of the matter is, if your dream is to travel across Europe and your job is the only thing standing in your way, then you'll soon realize the job isn't worth it.
If language isn't an issue, you may want to consider supplementing the cost of your travel across Europe with internships or postgraduate summer placements at corporate offices abroad. If English is your only language, then you might want to consider offering to teach: Teaching English as a second language can make for an exciting and fun way to meet new people and share your knowledge. A popular job amongst young Europeans has also been to travel as an au pair, or temporary live-in nanny to families with children. To fund your cost of traveling across Europe, you may even wish to consider jobs commonly needed throughout seasonal holidays. Try thinking outside the box: around the end of November or early December, flight prices are not as high as they will be around the start of the month, and post offices all over Europe will be burdened with the increased influx of Christmas cards. Researching post offices, submitting applications ahead of time, and planning ahead can make for a jolly couple of weeks while you work and save, or work to pay off your living expenses while living in the country of your choice.
In short, whatever your situation, don't allow the question of "How much will it cost to travel across Europe" become the thing standing in the way of you and your travels. Instead, ask yourself "What can I do to make it happen?"
