I went to the Peking Man World Heritage site by public buses from Beijing and it is quite a lengthy journey. The area is well looked after with neatly trimmed paths, good signposts and viewing points. I found the caves fascinating even though there is not so much to see. As a child, I was always interested in 'cavemen' and this was the real thing. There are interesting explanations in English at the various stopping points on the trail and you can go inside some of the caves.
