Singapore To Koh Tao, Flights, Trains & Ferry Times, Schedule & Prices
Several ferry operators can take you to Koh Phangan from here. There is a fast boat that takes just thirty minutes, another that takes a little over half an hour, and a slower 50-minute boat that can take you to Haad Rin. Depending on your itinerary, budget, and preferences, you can choose a ferry operator that suits your needs.
Before you make the final booking, it’s best to look at the departure times of each ferry since they tend to change, especially during inclement weather. This route can take anywhere from three hours to as long as seven, depending on the schedule of your flights as well as the ferries.
Another option is to fly from Changi Airport to Phuket. If you are worried about time constraints, this option may be better for you because there are more flights to choose from. The flights take an hour and 50 minutes. Once you get to Phuket, head over to the town centre to book a joint bus and ferry ticket. There are morning and afternoon departures, so if you don’t make it on time, it’s no worries since you can spend a night at Phuket.
Travelling from Singapore to Koh Phangan requires a little patience, but you’ll be rewarded once you see how spectacular the Thai islands are!
