Although it started small, the Urban Highline Festival has now become the biggest of its kind in the world. EpicTV recently released the first episode in a series about this year’s festival in Poland, focusing on the athletes who helped grow the slacklining community.

In its sixth year, the event has now reached a level where not only the top athletes attend, but a fair amount of beginners as well. Full of workshops, music, and light shows, it’s the place to be for dedicated slackliners.
