The Longmen Waterfall (龙门飞瀑 [Lóngmén Fēi Pù]; Dragon's Gate Waterfall) is one of the main attractions of the Longgong Caves (龙宫洞 [Lónggōng Dòng]; Dragon Palace Caves). This was actually an unexpected surprise for us as we had no clue that the Longgong Caves even featured a waterfall. And a distinctive, unusual feature about the falls was that it passed through a natural bridge or tunnel (though it did seem like the uppermost part of the falls had been man-modified for what appeared to be flood control).
From the well-established car park, we walked along a well-manicured paved walkway for about 15 minutes crossing over a couple of bridges, which themselves were perched over some smaller cascades and manmade waterfalls. I remembered there were quite a few young girls dressed in bright red Miao clothing looking for tourists wanting to pose for a photo with them for a fee. There were also a few peddlers selling corn and yam as well.
Once at the falls, there was a wet-with-mist viewing area which got a little crowded in waves from the large Chinese tour groups as well as many more of the young girls in Miao attire. The mega groups could be a bit trying on the nerves as I remembered one middle-aged guy rudely shoved me out of the way as apparently I was in his photo. Since I was able to appreciate the fact that a country with over a billion people required a bit of aggressive behavior in order to get by and survive (no place for manners in most circumstances, I guess), the annoyance was brief. But consider yourself warned if you come across this kind of behavior (not just here but throughout the country).
There was also a flight of stairs beyond the often-crowded viewing platform leading to an upper viewpoint that was a little quieter and offered a different perspective of the unusual Longmen Waterfall.
Back at the viewing area, a bridge proceeded to the right and went up some more steps through caves ultimately leading to another queueing area where there was a lake directly above the waterfall allowing for non-motorized boat trips through another cave further upstream. I remembered we definitely had to watch our heads as the boat frequently passed beneath very low overhanging stalactities and tree branches!
Directions: The Longgong Caves were combined with the Huangguoshu Waterfall in a day trip out of Guiyang. Even though we stayed at the Huangguoshu Waterfall area on our visit, I could easily envision tours doing the whole thing in a day. And that might explain why it gets pretty busy over here.
From Guiyang, it was about a 2-hour ride to get here.
