A small but growing segment of visitors have been clued into the existence of these districts and are embracing them, seeking to experience the hipster culture.
With all that said, perhaps it's worth pausing for just a moment, to define exactly what a hipster is (at least according to the WTM report).
The report's very academic definition of a hipster describes someone who follows the latest trends and fashions, particularly those outside the cultural mainstream. Hipster neighborhoods meanwhile, are typically places filled with pop-up restaurants, vegan cafes, independent shops and art galleries.
Interestingly, Airbnb is given a great deal of credit for playing a key role in opening up such areas to tourists, because many hipster neighborhoods lack hotels (at least for now), and private rentals are often the only option.
Among Europe's leading hipster capitals are Berlin's Kreuzberg neighborhood, District VII in Budapest and the Malasana district in Madrid, to name a few.
Adam Groffman, a Berlin-based travel writer, is a stereotypical hipster when it comes to his vacation choices and how he arrives upon them.
When the 31-year-old year visits a new place, it's often after doing research on Instagram or perhaps searching for someplace that hosts a good film or music festival. In other words, if you're reading between the lines here, the days of purchasing a staid or traditional guidebook issued by Fodor's or Lonely Planet, are perhaps fading among the hipsters.
"Finding places through social media is a great way to stay abreast of cool places," Groffman says. "Scour social media. On Instagram, you can search by location, and you find photos of different cities and places and you see things that look cool. It can become addicting."
Foursquare is another social media platform that Groffman suggests when on the hunt for intriguing new places to visit in a foreign city.
"Also, when I'm in a new city and I don't know where to go and what to do, I tend to look for record stores because usually they're going to be somewhere that's more edgy and alternative," he says. "And I talk to the people in the record store about the neighborhood, because they usually know about the alternative scene in the city."
Good to know right?
Groffman's travel blog, Travelsofadam, was actually referenced in the WTM report as one of the leading guides to hipster haunts, one that lists up-to-date reviews of the planet's ever changing hipster scene. Among the hipster destinations topping his list are Berlin's Neukolln neighborhood (just south of the city's center) and London's Dalston and Hackney communities.
Likealocal was also highlighted as a site to use when seeking information about such neighborhoods.
Some travel companies are also starting to jump on the bandwagon, offering hipster tours of specific city districts, often led by local residents to enhance the authenticity. Vayable is one such company highlighted in the 2015 trends report.
But ultimately, having a hipster travel experience simply comes down to being able to immerse yourself in a local, non-touristy, community, or its customs, events or traditions when traveling, having an experience that leaves you with some sort of unique and lasting knowledge to take home.
"Hipsters want to learn something or take something away from a holiday. And they want to want to have experiences with local individuals that they can take back," Groffman explains. "Its about being able to take this knowledge and incorporate it into your life readily, whether its new music, coffee of food. I went to this totally hipster music festival in Sweden, that was attended by all Swedish hipsters. It was very cool to just be in that community for a while."
So for those who'd like to get in on the hipster holiday trend, here's a look at a few other notable hipster hotspots. And remember, social media is the new guide to hipster travel.
