Good to know before you go
Leaving Koh Ngai
Koh Ngai (also written Koh Hai) is a small island with a handful of resorts along one long beach and very clear water. Boats drop guests at resort piers or on the beach.
Tell the boat crew the name of your resort when you board so they drop you in the right place.
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.
