Tai O is a unique old fishing village with laid back life style which you rarely get to see in the busy Hong Kong City. There are stilt houses along the waterways, they are home for the fishermen and the boats are the main form of transport to get around.
Somehow this area reminds me of some part of Cambodia houses by the river. But I never expect to get to see those in such a modern city like Hong Kong.
There are some places you could stay if you like to get away from busy Hong Kong City.
Bus : can take bus to MTR Tung Chung station then to the city area
Ferry : from Tai O to Tung Chung and Tuen Tun from these points and public tra sport is available to other destination.
