Ladies and gentlemen, your attention, please. Our bus will arrive at Victoria Park in a few minutes. You can feel the comfortable cool air coming from the lake on our left. This is a favorite place for tourists in summer, especially on a hot summer afternoon like today. This lake is one of the great wonders of nature. No one knows when and how it was formed, but people began to build houses around the lake a hundred years ago, so in this park you can have a special view of houses of all shapes, styles and colors. In late autumn and winter, this park is the best place for bird watching. School teachers like to bring children here and they just love it.
   Now our bus is driving around the lake. You can sit back and enjoy the beauty of everything here. The bus will take us to a good spot, where you can take the most wonderful photos you have ever taken.
   Here we are! Please get off and enjoy yourselves. Return to the bus in 30 minutes and then we will climb the mountain five miles away and have our dinner after that. See you! Questions:
