The best way to visit a city, in addition to the city's violent walk, there is actually a more convenient and fast way to visit, that is, a tour bus tour. In St. Petersburg, we tried the 2 day bus tour of City Sightseeing, which satisfies my lazy needs. The ticket purchase location is in the bus ticket office under St. Isaac's Cathedral. The red bus is divided into 1 line and 2 lines. Line 1 is the red line, on the south side of the Neva River, mainly to visit the attractions near Nevsky Prospekt; the 2nd line is the green line, which will pass through the Neva River to the north side of the Peter and Paul Fortress. The two lines of vehicles are all red buses, just look at the numbers on the car to make a distinction, each car is about 20-25 minutes apart. The red line has a Chinese voice introduction, and the green line does not. But in terms of scenery, the 2 lines are more beautiful! The picture shows the route of the bus. Remember to take the bus to the right.
