From Bangkok, the usual route is to Chumphon — by overnight train (about 7–9 hours), bus or a short flight — and then a high-speed catamaran, which takes around one and a half to two hours. Joint tickets sold by the ferry companies cover the bus, the transfer to the pier and the boat in one booking, and overnight combinations deliver you to the island by mid-morning.
From the south, catamarans run several times a day from Koh Samui (two to three hours) via Koh Phangan (one to one and a half hours). Slow overnight boats also sail from Surat Thani. All boats arrive at Mae Haad pier, where pick-up taxis wait.

Getting around Koh Tao
Sairee and Mae Haad are joined by a walkable beachfront path. Elsewhere, shared pick-up taxis charge fixed per-person fares that are high for the distance, and longtail taxi boats serve the bays. Scooters are rented everywhere, but the island’s roads are steep, sandy and unforgiving, and rental shops are known for charging heavily for scratches. Photograph the bike beforehand, never leave your passport as a deposit — or simply walk and take boats.
