I like to eat durian and I didn't buy any durian to eat at Krabi Island, near to hotel doesn't have durian to purchase.
I bought this dehydrated durian pack from Krabi Aiport, it's most expensive durian I bought. No kidding it cost me 300 baht which mean RM30. Inside of this pack only contains of 3 packs, you can see just like above picture. So small packs and so little to eat. I can tell you I am not satisfied with this durian and it's not taste as good as durian we have in Malaysia.
For your info, this dehydrated durian taste no good and I don't recommend it.
Not many shops in Krabi Airport, I am sure you seen more shops in KLIA 2.
