How much will it cost from HK Airport going to Ocean Park via MTR, bus or taxi?

There is no direct MTR from HKIA to the park. By bus, transfer is needed. I suggest you take airport express to HK Station first. The ticket fare is 100 HKD per adult. Then walk to Central Station and take Island Line to Tin Hau Station. After arriving, take bus no. 629 to the ocean park directly. The ticket fare is 10.6 HKD and 5.3 HKD for children.

If by taxi, it will cost 320 to 330 HKD.

Thanks for your reply. How about if we opt to take MTR from HKIA to Admiralty Station before taking a bus no 629 directly to the Ocean park. Will the cost be lesser for us? Otherwise we will just take a taxi since we are group of 3 and will incurr the same transpo cost taking bus or taxi.

Thanks much. please reply.
