The Potsdam gardens offer not only an English style and formal garden, but also a choice of palaces. Sans Souci being the most famous, the other palaces and buildings are also worth lokkimg into. There is for instance a lovely Chinese pavillion, which is unique. Go, and take several hours or a whole day to wonder around and enjoy. The gardens are accesible by S-Bahn from Berlin, and then a local bus or tram. If you have a Berlin public transport pass, you can also use it in Potsdam.
