This article is a travel topic
So you want to be a travel writer. It sounds like a dream job: free vacations to exotic far-off lands, a fat corporate credit card for paying all your expenses, a big paycheck as reward and your name on the spine of books at every airport in the world.
Alas, many others think so too, making travel writing one of the most brutally competed and poorly paid professions around: an accepted and published two-page article in an average publication may net you around US$150. Now figure out how many you'll need to sell to make minimum wage, and you'll realize with very few people can scrape together a living from it, much less get rich, and it's difficult to even get your foot in the door with so many others vying for the same jobs.
An aspiring travel writer will need the following skills:
Travel writing has specific requirements.
You've sweat blood and tears perfecting your travel diary, the magnum opus My Summer Holiday in the Podunks. Will publishers tear it out of your hands and compete for offering the highest advance? In a word, no. Book-length travel writing is as hard as becoming a published fiction author, only more difficult, because everybody thinks they can do it.
If you want to just publish a few copies for your friends and family, look into a print-on-demand service like Lulu . They will even sell your book online for you, and who knows? Maybe you are the one in a million that makes it.
Writing guidebooks (lots of them) can pay enough to be a job, but it's hard, monotonous work reviewing every identikit concrete barracks in Bangkok/Khao San Road. And with Wikitravel lapping at their heels, how long can traditional guidebooks sustain themselves?
Lots of magazines and newspapers write about travel, and this is probably your best bet. However, there are many types with slight differences, and it's worth paying heed to them.
Dedicated travel magazines run the gamut from high-end glossies like Travel + Leisure  and Conde Nast Traveler  to backpacker operations like Farang . Instead of aiming for the big names or the all-purpose titles, which probably already have better writers than you going to more interesting places than you, aim a step below at smaller, regional, more targeted magazines: AsiaSpa  is for travelers in Asia interested in spas, Ski Canada  is for travelers in Canada who like skiing, etc. The obvious downside is that, as in trade magazines (see below), you'll need more than a passing familiarity with the special interest in question.
Online travel magazines are another option for breaking into travel writing. Websites can include everything from highlighting worldwide locations like Brave New Traveler  to articles focusing on particular story angles such as 52 Perfect Days  where all articles are written based on how to spend a perfect day or evening.
Online travel blog-a-zines websties have a completely independent and still professional approach to several topics about travelling such as destinations, resources, news, etc. For instance, | Travel Generation is aimed to the backpackers niche.
In-flight magazines, found for free in every major airline's seat pocket, are also all about travel writing. However, their function is to get people interested and drive up sales, so articles have to be enticing and gloss over bad points. The upside is that, if hired, you can expect to get free tickets to your destination (you're limited to where the airline flies, of course), free accommodation from advertisers (you'll be expected to write a glowing review) and, if you're lucky, free elephant treks, river rafting or whatever is the expensive, touristy thing to do at your destination (ditto). The magazine will pay you freelance writer rates, and all other expenses come out of your pocket.
Trade magazines focus on entirely different industries from travel, but as people like to keep abreast of what's happening elsewhere in the world, they're often interested in travel reports. The range of these is incredible: the Masonry Magazine  runs a regular feature called "Masonry Around the Nation", reporting on what kind of interesting buildings have been built from bricks. The flip sides, though, are that they're not going to pay for you to travel and that you need to be familiar with the industry in question (or good enough at interviews to be able to fake it).
Newspapers often have travel sections and they may be interested in freelance work, especially if you can work in an angle that somehow relates to the home city. Again, local newspapers are easier (and pay less).
