Prepare yourself for a day of excercise and a day you will never forget. Ofcourse you may have your doubts while climbing the stairs for hours on end to reach the top. Is it worth it? For a few of you I realize that might be a no, because it is a tough walk up this mountain, particularly in the summer. For the vast majority of people, they will not only be glad they trekked up the mountain, but will be wowed by a Tang Dynasty Temple and an incrediblely large mountain surface inscribed with Chinese calligraphy. Much of the temples have been heavily renovated, or even rebuilt, but it takes little from the experience. Mount Taishan is a beautiful place both from a natural standpoint and a cultural one. The view is spectacular, though it can be sometimes a bit foggy (partly from pollution) unfortunately. My only negative, is on top of the mountain there is a bit too much tourist activity going on, but how many WHS in China don't have this problem? Overall, a wonderful experience I will always remember.
