hello, several questions here, which is the best way to get from causeway bay to ocean park in HK?,

From Causeway Bay, you can walk to the Causeway Bay Station to take the MTR Island Line to Central Station. Then walk to the HK Station to take the Tung Chung Line to Tsing Yi Station and get out of the station from Exit C. There you can find the shuttle buses for the Noachs Ark.

To Disneyland, you need to follow the first method to HK Station to take Tung CHung Line to Sunnay Bay Station. Then change to Disneyland Resort Line to Disneyland directly.

To the Ocean Park, you can take the Island Line to Admiralty Station and then walk to the Admiralty West to find the bus line 629 to reach Ocean Park directly.
