Option 1: Raja Ferry Company from Nakhon Si Thammarat Airport to Koh Samui
The Raja Ferry also takes 1 hour 30 minutes to reach Koh Samui. Although the boats used by the Raja Ferry are slower they have less far to travel because they arrive at Lipa Noi Ferry Pier which is on the West Coast of Koh Samui. The wait between the arrival time at the ferry pier and the time when the ferry departs is 30 minutes. The arrival time allows for 60 minutes from the time the ferry arrives in Koh Samui to complete the minivan transfer from Lipa Noi Ferry Pier to your final destination in Koh Samui.
- About the Raja Ferry Service
The Raja Ferry Company has a fleet of large car ferries which it uses on the route between Donsak Raja Ferry Port, on the Thai mainland, and Koh Samui. The Raja service is used as much by Thai people travelling to Koh Samui, often in their own cars, as it is by foreign holiday makers. The car ferry is not a luxury option but they are comfortable enough for a 90 minute sea crossing. These large ferries have plenty of seating on foam and vinyl covered seats, as well as toilets, a shop selling drinks and food, and outside areas. One of the advantages of travelling with the Raja Ferry Company is that the car ferry can complete the crossing in almost all weather conditions. Raja ferries are large enough to cope with large waves and are rarely cancelled due to the weather.
