HuangShan

The mountains have steps carved in their side so you can conveniently walk up. The steps are 7.5 (Eastern) or 15 (Western) km long, and since they rise about 1000 m you'd think it wouldn't be too steep; but since they rise about 15 km and drop about 14 km to get to the end, it's actually a fairly grueling walk, especially for those with arthritic knees. We puppied out by taking a cable car the second half of the way. If you look closely at the picture of the Western Steps you can see a cluster of people right at the right side of the mountain; they're huddled together at the base of the Hundred Steps, which run up through that crack in the rock and which are as much fun as they sound.
