Underground in Vietnam: Caves, tunnels and wine cellars

on building upwards, but what's happening underground is perhaps more
exciting than the latest skyscraper -- think hidden caves large enough for
40-story buildings and wartime tunnels traversing the earth beneath your
feet.  Here are some of Vietnam's unique sites below the surface. 
World's biggest cave A Manhattan city block, buildings included, would fit
quite nicely inside parts of Son Doong cave in central Vietnam's Phong
Nha-Ke Bang National Park. But you won't find anything remotely urban here.
In the world's largest cave passage lofty stalagmites, some shooting as
high as 70 meters, stand in for concrete office blocks while shafts of light
from above have led to wild gardens taking root on the cave's floor. Son
Doong is one of the many caves underneath the 85,754 hectares of park, which
holds UNESCO World Heritage site honors. While the limestone karst landscape
on top is impressive, the system of caves, grottoes and underground rivers
give visitors a distinct "Journey to the Center of the Earth"
