A long time ago in a galaxy far far way it was very difficult to get to this tropical island paradise of Koh Tao!
The ferries to paradise from Koh Samui or the mainland were infrequent and usually very cramped with materials and goods for Thailand. Thankfully over time this has changed and you can easily reach paradise from where ever you are in Thailand or beyond.
 
If you arrive in Bangkok, you have many choices.
Fly and ferry: From Bangkok’s international Survarnabhumi Airport, there are flights to Koh Samui every hour, so if your arrival allows, you can fly in the morning and hop on a ferry to Koh Tao at lunch time, arriving at 2:30 or 3pm depending on which ferry company you travel with, though the Seatran pier is closest to the airport.
Fly and ferry: From Bangkok’s Don Mueang International Airport, there are flights to Chumphon twice a day and flights to Surat Thani several times a day. The flight to Chumphon, is best as this is a early morning departure, meaning you can then catch the lunch time ferry with Lomprayah to Koh Tao. Arriving at 2:45pm in paradise. If you take the early evening flight then you could catch the night ferry to Koh Tao arriving at 5am the next morning, or stay the night in Chumphon and catch the morning ferry the next day.
Flights to Surat Thani can also mean you may spend the night there before arriving the next day in paradise.
Trains and ferry: Many trains leave Bangkok heading south, the overnight express is best as this will arrive in Chumphon early enough for you to catch the morning ferry. Try not to go as far as Surat Thani, as these will mean you have gone further than you have to and the journey will have cost you more.
Buses and ferry from Bangkok to Chumphon: This is the cheapest way to get to paradise with buses leaving Khaosan Road at 9pm or 5am. These tickets are easily purchased from Khaosan roads Lomprayah and Songserm shops or any travel agency in Thailand. These arrive at Chumphon, from where you catch the morning ferry or the lunch time ferry departure.
Day time ferries depart from Chumphon, Surat Thani, Koh Samui and Koh Phangyan and the night ferries depart from Chumphon (no Sunday departure) and Surat Thani.
