We enjoyed two days in S. Petersburg and wished we had more time. The museums have already been mentioned by other reviews we heartily agree with the positive comments about the Hermitage. We had a chance to travel by subway, which is a world all by itself, just don't try to take photos, the police do not allow it. We also visited the Kuznechny Market which was really fun. The vendors try to sell piles of unusual things and foods we had no name for. It was difficult to get rubles because there are few places to exchange currency. One of the most interesting places we saw was the Church of Our Savior on the Spilled Blood just a block off the Nevsky Prospekt. There is a great open air market on the square behind the cathedral where you can buy Russian "stuff". Just be aware that what looks like traditional Russian crafts are most likely mass produced someplace else. A walk along the Nevsky Prospekt was really fun. You will see the great train station, Kazan Cathedral, and other grand buildings. Our favorite thing aside from the museums was the canal boat ride through the city and along the river. We were warned not to get off the main streets as it was not safe for tourists and that people had no time for tourists. Our experience was that people were eager to try out their English and were helpful and friendly.
