Bahasa Malaysia is the main language that is spoken in Langkawi. All banners, posters, instructions will be given in this language but most of the boards and instructions are translated and put up in English. Most people can converse in English even though they are not very fluent. People are extremely helpful so if you are unaware, confused or lost you can always ask for assistance from the locals. If you are staying at a Langkawi Resort you can always get details and information from the staff as they will be fluent in English
