Hi! We are coming to St. Petersburg in mid-December. I do not mind exploring the city on my own but my friend says that in St. Petersburg it is be better to join some organized tours. I’ve already checked the possibility to hire a private guide, but I think this is a bit too expensive for us. What I know by now is that there are hop-on-hop-of busses which hopefully run in December still. Are there any other tours to join? My friend is French, so both - French or English would be fine. We would like to join a nice walking tour to see something one usually would not see when on the bus. Also we would like to see the Hermitage, the Catherine Palace and Peterhoff. Maybe something else as well. All the information and advice you may give will be appreciated!
