According to this website, there are direct ferries from Aberdeen Pier, Hong Kong to Sok Wu Wan on the Lamma Island. Are there ferries from Aberdeen to other places? For example, to Mui Wo (or other parts of the Lantau Island), or to Central, or to the Kowloon Peninsula?
You can go a lot of places from Aberdeen Pier in Hong Kong, though they are mainly outlying islands.
According to the Transport Department in Hong Kong, there are two franchised/licensed ferry line that departs from Aberdeen Promenade that gets you to Lamma Island:
Furthermore, according to Traway Travel Limited, they operate two more routes (in addition to 1.) from Aberdeen as of 2019:
Aberdeen - Stanley / Po Toi Island
Aberdeen - Cheung Chau (Alternate link)
There are also two river crossings (kaito) routes between Aberdeen Promenade and Ap Lei Chau (main street), and a ferry service that gets you to the Jumbo Kingdom, a pair of floating seafood restaurant nearby.
The OP also asked:
Are there ferries from Aberdeen to [...] Mui Wo (or other parts of the Lantau Island), or to Central, or to the Kowloon Peninsula?
As of 2019, no, at least not directly:
- Mui Wo is served by ferries to/from Central, Cheung Chau and Ping Chau only (Link to the ferry wiki in Hong Kong, Chinese only);
- Central is better connected via minibuses; and
- By extension, Kowloon Peninsula, which is further to Aberdeen in Central, is too far to make travelling by boat practical.
