We have just spent 4 days in Beijing on a stopover on the way to Europe - our reflections of that busy busy city are:
The Sights - We managed to see most of the tourist sights in Beijing – the Great Wall is amazing, snaking its way across the mountain tops for miles as far as you can see. There are 3 main sections you can reach from Beijing, and we chose the Mutyianu part which is about 60kms away and has a gondola to the top making it easy to get up to the best photo taking areas ( you can walk up but in 35 degree heat its probably not a good idea)
. The wall itself was originally 6000kms long and was built to keep out the mongol invadors from Beijing. It has recently been restored in several areas and understandably is now one of the world's top tourist attractions.
