I was unsure whether to give three or four stars. It is a very nice place: the mountain is beautiful, the hike difficult and it holds an important place in Chinese culture - being the most important of the 5 sacred mountains of taoism. However, I think due to its fame, it is very busy, and if you go during holiday periods, when you climb the steep mountain, there are so many people, you could literally lean backwards and not worry about falling! I personally think Hua Shan in Shaanxi is more beautiful and has better hiking.
