The only option to leave the island is by return air charter flight.The process is that you settle up your bill the night before. A wake up call on your room telephone occurs at 6.45am. You and your luggage are weighed about 7am. You have a basic breakfast. Your luggage is loaded into the plane after it has arrived with the fresh faces from Kota Kinabalu. You depart somewhere around 8.30am.
Travel back to Kota Kinabalu by boat is a very long option 16 hours and not readily available to the scuba diving traveller.
