as I mentioned before on my pictures, the Great Wall starts from Shanghaiguan on the shore of bohai sea. about 4 km after the shore to west direction, the Wall continues on mountains. Tehre is a public park for visiting the mountainous part of Great Wall in which there are a lot of steps to arrive one of the top towers.
There is also a cable car, which passengers can use it to access the upper parts of the Wall. I didin't use it myself and don't know the price of it's tiket.I climbed the steps and visited the top tower which was fantastic and had a great view to mountains and Shanghaiguan town as well as Bohai beach.

I returned from Huludao to Beijing by bus during my last accomodation in China on Aug. 2003.
The bus started the trip on-time from downtown of Huludao. It was a clean and comfortable bus with a polite young girl who was acting as an attendent. the passengers were served with a bottle of water and a pack of snack during the trip which took 4.5 hours until Beijing. The final destination of bus was Xikorzan bus station in Beijing. From there, I went to Xidan and took a bus in front of Central office of AirChina to Beijing International Airport and paid 16 Yuans.
