To Cheung Chau by ferry 以渡輪到達長洲

The main ferries are to/from the Outlying Islands Piers (Pier 5) in Central. From here, you can catch two types of ferry: large, regular ferries that take around an hour, and “fast” ferries taking around 35 minutes.

There’s also a ferry service – always a (small) slow ferry! – between Cheung Chau and Peng Chau, stopping en route at Mui Wo on Lantau and, less often, at Chi Ma Wan to the south of Mui Wo.
Schedule
