The kai-to, sometimes kaito or kaido (Chinese: 街渡) is a type of small, motorized ferry operating in Hong Kong. They are usually used to serve remote coastal settlements in the territory's outlying islands.
There are currently 78 fixed kai-to routes, mostly used to ferry passengers between the outlying islands of Lantau Island, Peng Chau, Cheung Chau, Lamma Island, among others, to the west of Hong Kong, and to enclave villages in the Tolo Harbour, Double Haven, Port Shelter, etc. in eastern New Territories.
Certain routes within Victoria Harbour are still served by Kai-tos, including the Sai Wan Ho to Kwun Tong route.
