Berlin is one of those cities that truly has it all—street art, cultural attractions, historic museums, and a fascinating urban bike scene. As I found out during my trip to Berlin last summer, the city also has its very own beach.
Badeschiff an der Arena (actual location is Eichenstraße 4) is the perfect place to unwind. The swimming pool is built along the Spree and literally overlooks the water. There's also a cocktail bar and spacious lounge areas, so regardless of when you visit, it feels like a party.
To get there, hop on the U1 at Schlesisches Tor or take the S-Bahn to Berlin Treptower Park. Admission is rather affordable at around €5.
