Living root Bridges are built in the deep valleys of East Khasi hills in central Meghalaya, Northeast India. The people of these villages (Nongriat, Laitkynshew and others) are isolated from rest of the world as these are located in a deep valleys which can only be reached by an arduous trek. Now though the situation is better as there are steps built to visit the valley. You have to descend and climb more than 2100 steps at a time. Since these valleys were inaccessible for a long time people came with this ingenious solution to cross rivers which were very full due to tremendous rainfalll in the monsoon.
