I want to know: how to get to Shengtian Lake from Chongqing Southwest University (Beibei Campus) by bus? How long and how much?

If you leave early, you can take a bus directly to Jindaoxia at the old passenger station. There are many people on May Day, so it is recommended to leave early. You can also take the bus The price is not expensive, not more than 20.

If there is no bus to Jindaoxia, you can only take a bus to Liu Yin, and then take a black car to Shengtian Lake in Liu Yin, about 10 yuan/person. You'd better remember Master's telephone number and ask him to come back and pick you up the next day.
