Berlin – Köpenick – Schlosspark
If you want to relax a bit, drink a beer after work and listen to music, then you should go and visit the Schlosspark on a wednesday evening. They have different bands and musicians playing every week at around six and the best thing is – it is free. There is a restaurant there:
Where you can sit outside at the water, eat and drink something and listen to the music if you like.
Or you bring a blanket and sit on the grass
You can even go for a walk and have a look at the beautiful garden and the castle. It is actually quite nice there.
