My husband and I are in Bangkok this August and we would like to go to Perhentian Islands. The cheapest way is to go to Narathiwat Airport from Bangkok and from Narathiwat Airport to Kuala Besut by land. I've found from Tripadvisor forums that there is a van from Narathiwat Airport to Thai/Malay Border. How I can go to Kuala Besut from the border? And is this route I am taking between Narathiwat to Kuala Besut safe to travel?
