Have you ever wanted to travel abroad but felt you couldn't afford it? Guess what? You don't have to be super rich to travel abroad; you just need to be clever. Here are five of the cheapest ways to travel abroad.

Book Cheap Flights

If you want to travel cheaply, you should start your trip research on sites like Skyscanner. Skyscanner is one of the best ways to find deals on flights from hundreds of different airlines all in one place. You can even sign up to be alerted whenever there is a drop in price on one of the flights you want to take. The site works in many different countries, not just the U.S. You still might have to act quickly though, as sometimes the flight deals disappear fast.

Go Where You Know Someone

I have been lucky enough to have traveled to Italy several times, but I never would have been able to afford it on my salary had it not been for the fact that I knew someone there who let me stay with them. Knowing someone in the country you want to stay in can really save you a lot of money on hotel bills—and it can be helpful to have someone to split ticket prices or food bills with. I got to know my Italian host through years of talking to each other as pen pals, but many people stay with old acquaintances that moved abroad for work or other reasons. You could also stay with relatives that you don't get to see very often.

Travel With a Friend

Not everyone knows someone in the country they want to visit, but that doesn't mean you're out of luck. Traveling with a friend from your own country can also be a cheap way to travel abroad. You will still have to pay your own airfare, but once you arrive you can split the cost of everything else. Tag team on restaurants, hotels and even souvenirs.

Pay Your Way Through Work

Everything costs money. No one gets a free ride, but if you are willing to work a bit in your free time, you may just get a free place to stay. Websites like Hostelworld can link you up with hostels that are short-staffed and looking for short-term labor. If you can work a desk or clean up after some of your fellow residents, you could end up staying at the hostel for free or at a deeply discounted price. This option is great for backpackers who would have been staying at a hostel anyway, and who are in their destination country for longer than your usual tourist. Saving that much on your accommodations can allow you to do a lot of other things you may not have been able to afford without it.

Do a House Swap

Swapping houses might seem like a Hollywood invention (if you've ever seen The Holiday with Kate Winslet and Cameron Diaz, you'll know what I mean), but it is more than plot fodder. It works by linking a person who wants to travel to a certain country to a person in that country who wants to travel to theirs. The two exchange emails and information, and effectively switch houses for an agreed-upon period of time. You might not end up snagging a guy like Jude Law in the process... but it would certainly be interesting to see how the other person lives.
