In the location's words:

RollersClub Cologne is the place to be. Here you can skate, party and organize your own events . The location in Ehrenfeld is perfect for birthday parties, corporate events and party nights with your friends.

Whether you are a beginner or a professional, everyone will get their money's worth here. You can let off steam while rollerblading or just chill out and listen to good music. The RollersClub Cologne is easy to reach and offers a unique atmosphere that you won't find anywhere else.
If you don't have your own skates you can rent roller skates and also protective clothing for a small extra charge. NICE!

So, get your skates out and come by!
