Flights to Koh Tao: Budget Guide
Koh Tao is where half the world's backpackers get their PADI cert — and at $250–300 for Open Water, it's the cheapest place on earth to do it. Daily budget runs $35–42, and there's no airport, so you're taking a ferry from Surat Thani or Koh Samui.
30-day Koh Tao budget
At $35–42/day, Koh Tao is all about the dive. Dorms run $12, pad thai is $3, and the PADI Open Water course ($250–300 including accommodation) is the main draw. Once you're certified, fun dives drop to $25 a pop.
Flights to Koh Tao from your city
There's no airport on Koh Tao — fly to Surat Thani (URT) and take the Lomprayah catamaran, or fly to Koh Samui (USM) and grab a shorter ferry. URT is cheaper (budget carriers), USM is faster but Bangkok Airways has a monopoly on that route.
