hey man.
I going to CPH next week and I'm definitely going to skate "Nørrebro Skatepark" every single day.
its the best spot in whole DK and I've been skating in DK for the past 8-9 years. so I think you should totally tjeck the park out, it's amazing!!
just go to the part og CPH which is called "Nørrebro" and then just ask your way. it's not so difficult to find.
any ways, I hope i could help you in your search for good spots in CPH. Have a great trip.
