Are you ready to embark on an adventure and travel back in time to the Cold War era? Teufelsberg, an abandoned spy station in the midst of Berlin's Grunewald forest, was once used to intercept Soviet communications during that time. Start your journey and you'll have the opportunity to listen to the echoes of the past and present.

Are you tired of following the beaten path when you travel to a new city? Do you want to discover the real Berlin, beyond the tourist traps and guidebooks? Then it's time to get lost in the city and see what you can find!

Board games are back and bigger than ever. Whether you're a hardcore gamer or just looking for a fun night out, board game cafes offer a cozy atmosphere, good company, and of course, plenty of games to play.

I live in a big city and I see people like you every day: getting off of trains, bursting with enthusiasm; pouring into the hostels and out of the museums; rubbing your hands together and asking, “So, what’s next?” I have been in your shoes many times, because I love visiting new cities too. But to be honest, feeling like an outsider kind of drives me nuts.
