The main entrance to this cave is 2km from Ban Gioc Waterfall, just off the road to Cao Bang.
Nguom Ngao is one of the largest caverns located inside a mountain among the range of limestone mountain in Gun hamlet, Dam Thuy commune, Trung Khanh district.
The cave is enormous (about 3km long) and one branch reaches almost all
the way to the waterfalls, where there is a 'secret' entrance.
Normally
a guided tour will take about an hour and will only go about 400m into
the cave; ask if you want to see more. The price remains the same, and
a full tour takes about two hours.
Mains electricity is due to be installed, but it's probably sensible to take a torch.
The
cave was formed due to weathered process of limestone mountains over a
long time. Stepping in the cavern, we seem to see a miraculous world.
From high stone cliffs, hanging wonderful sparkling seven-colored
stalactites. The nature busy with its work over a long time to create
attractive stone statues of which some look like human bodies, some
look like forest trees, animals of fairy tales, or a fairy combing her
hair, or a good divine, or a huge lotus bulb. Stalactites seem to grow
from the soil, or hang down, vertical or horizontal with small and big
figures piled and fixed in a hustle indulging visitors.
Wonderful
beauty of Nguom Ngao spreads the cavern. According to figures given by
the British Royal Investigator Group in 1995, Nguom Ngao is 2,144m long
including 3 main entrances namely Nguom Ngao, Nguom Lom and Ban Thuon.
