Phi Phi doesn't have an airport. Since it is a group of islands the standard way is to reach by ferry which will take approximately two hours from Phuket and one and a half hours from Krabi.
Ferries run to and from major places like Phuket, Ao Nang, Rai leh, Ko lanta and Krabi. Private water vessels and tour operators also run at a regular frequency.
