There are a few ways to get there. You can either choose to get there by Air,or by Ferry.
Getting There by Air
Malaysian Airlines (MAS) and Air Asia operate daily flights to Langkawi from Kuala Lumpur. International travelers from certain places such as Osaka, Taipei and London can connect with MAS flights directly from their country or other airlines, depending on their availability in that particular region.
Air Asia is the airborne version of a cheap local minibus, so you can’t go wrong if you’re looking for a good deal without the frills. Visitors from Singapore can use Silk Air which also flies directly to Langkawi daily.
