It was quite an adventure buying a train ticket and finding the right train at Baltic station in St. Petersburg. We had to ask in Russian to be sure to get on the right train. The journey itself is very entertaining as there are constantly vendors coming into the carriage trying to sell all sorts of things including band aids and tooth brushes.
Get off at the 14th stop, the first Oranienbaum one.
Another option is taking a marshrutka (minibus) from Prospekt Veteranov Metro Station.
Favorite thing: Unfortunately, everything is falling apart. Each pavillion and palace costs extra but the park entry is free.
In the Grand Palace we were allowed to walk around by ourselves instead of the compulsory tour as we said that we don't understand enough Russian. There are some things in German and French to read.
The public toilet is near the Grand Palace, bring some toilet paper!
Fondest memory: The vast park that surrounds the palaces and the market (some of it in a building) on the way from the railway station to the park.
