Good to know before you go
Leaving Koh Tao
Koh Tao is a small, rocky island known around the world as a place to learn to dive. All passenger ferries dock at Mae Haad, the village on the west coast, a short walk or taxi from Sairee Beach.
Koh Tao is the most exposed of the three islands. If the sea is rough, sit low and near the middle of the boat.
