Good to know before you go
Leaving Railay
Railay is on the mainland, but limestone cliffs cut it off from the road, so every arrival is by boat. Ferries between Ao Nang, Phi Phi and Lanta stop off Railay and passengers transfer by longtail, so expect to wade or climb down to a small boat with your bags.
Pack light: transfers to and from the big ferry are by longtail and you carry your own luggage across the boats.
Arriving in Koh Yao Yai
Koh Yao Yai is the larger and quieter of the two Yao islands, with rubber plantations, Muslim fishing villages and views of the Phang Nga Bay karsts. Boats come from Phuket’s east coast and from the Krabi side.
The island is big and has little public transport. Arrange a transfer or rent a scooter at the pier.
Weather and season
Best November to April, when the sea is calm. From May to October the south-west monsoon brings swells; big ferries keep running but many speedboat island-hops stop.
