The Tourism, Arts and Culture Minister said this requirement applies to fully vaccinated tourists who plan to travel by land.
"They will need to at least use the transport services provided by travel agencies from their respective starting destination to the jetty in Langkawi," Nancy said during a press conference.
She added that travel agencies will help tourists to apply for permit from police to travel to Langkawi.
Meanwhile, those who are travelling by flight or from the neighbouring states of Kedah and Perlis don't need to go through travel agencies. Travellers, however, will still be required to apply for permit from police.
"We urge people who want to travel to Langkawi to comply with the SOPs that have been set to ensure that the tourism bubble pilot project is successful," she said.
Nancy also announced that the island will be opened to domestic tourists from all states, including those under Phase 1 of the National Recovery Plan (NRP).
However, those in localities under the enhanced movement control order will not be allowed to travel under the tourism bubble pilot project.
Most tourism activities will be allowed to resume under the tourism bubble pilot project in Langkawi. These include hotel stays, recreational and cultural activities.
