What happens when we arrive in Sabah Borneo?

After you pass through Malaysian Immigration, collect your luggage and then you will go through Customs.
If you are arriving the day before your trek, you will be met at the airport. You will then be transported to the Hotel where you will be checked in.
If you are arriving earlier than the day before your trek, you will need to arrange with the Hotel for airport transfers. I would suggest when booking your extra night accommodation that you request with the Hotel for airport transfers.
