From chunking mansion how to go to ocean park, giant Buddha ? And how to get back from there?

To the park, I suggest you walk from Chungking Mansion to New World Centre, Salisbury Road stop to take bus no. 973 to get off at Wong Chuk Hang San Wai, Wong Chuk Hang Road and then walk to Ocean Park.

To Giant Buddha, you can walk to Tsim Sha Tsui MTR station to take Tsuen Wan line to Lai King, where transfer to Tung Chung Line to get off at Tung Chung Station. Then walk several minutes to cable car station to take cable car to the Buddha.
