By Ferry

Ferries cross from Satun in southern Thailand to the Malaysian island of Langkawi, while over in Narathiwat province, a vehicular ferry shuttles between Tak Bai and Pengkalan Kubur, near Kota Bharu in Malaysia's Kelantan state.
There are also occasional cruises from Malaysia and Singapore to Phuket and Bangkok, the main operator being Star Cruises, but no scheduled services.
