If you would like to visit the Great Wall. I think the most well kept segment of the wall is near Beijing. there are plenty of tours that go up there, but beware of the scammers in Beijing that solicit such tours especially near Tienanmen Square and the Forbidden City. I remember being in the forbidden city and seeing one woman ask me if I would like to go on a tour, me and my friend turned her down. The next day we went to the great wall through a tour offered at our hostel. Dragon Inn Hostel. Was completely worth the money because we encountered the woman who was soliciting tours of the great wall the day before in the forbidden city. While we were at the Great Wall. She had two Americans with her they were shocked to see me and my friend me being american my friend being canadian. Anyway when the two american tourist were exploring the wall. The woman that was the tour for them came to us since she saw us from yesterday, and asked my friend in mandarin for directions, and when he and I didn't have the answer she needed, she left the wall, and left the two american tourist (a mother and her son). It was quite messed up because she charged them 500 RMB, we only paid 120 RMB for our tour, and it was quite organized because the hostel had covered a lot of the expenses we didn't have to worry about. Anyway just wanted to warn you when visiting China these things can happen and in fact this is common in any developing country.

Great wall is a wall, which is stands around the China border. It is really very attractive and wonderful wall. Many people come China to see the great wall and walk on it. If you want to go China and know about Great wall of China, you can visit :www.trekclub.org

The Great Wall is not located in any one given city. Some areas of the Great Wall offer magnificent vistas and picture-perfect brick-and-stone watchtowers, whereas older, pre-Ming areas may be in disrepair yet would certainly impress any archeology aficionado. Very early parts of the Great Wall were constructed from tamped-earth and, where possible, stone. These areas of the Wall are particularly prone to erosion and deterioration.The modern day Great Wall crosses Liaoning, Shanxi, Shaanxi, Sichuan, Jilin, Shandong, Hubei, Hunan, and Gansu provinces; Beijing and Tianjin municipalities; Inner Mongolia and Ningxia Autonomous Regions.

Hi all,
The Great Wall stretches across North China from east to west for over 6,000 kilometers. It extends from the shanhai pass at the seaside in the Hebei province in the east to the Jiayu pass in Gansu province in the west.The sites of the Great Wall stretch across 15 provinces of China.
But since the great wall in Beijing is very long and protected well while most of the great walls in other China areas are not kept well and opened for tourists, it is commonly thought Beijing is the only place to see the Great Wall.

If you want to go for a tour then by contacting with a travel agency is better & according to me complete India & Asia is providing best tour package for China tour.
Thank you.
