Koh Samui to Koh Tao: Your Gateway to World-Class Diving

Two Islands, One Gulf

Koh Samui is the Gulf of Thailand's luxury hub — international airport, five-star resorts, sophisticated dining, and beach clubs that wouldn't look out of place in Ibiza. It draws a different crowd than the backpacker islands to the north, and for good reason. But for divers, Samui is a gateway, not a destination.

Koh Tao — three hours north by ferry — is where the diving happens. With over 70 dive schools operating in 21 square kilometres, it certifies more divers per year than anywhere else on earth. The water is warm and clear, the marine life is exceptional, and the prices are a fraction of what you'd pay anywhere in the Western world.

If you're in Samui and haven't already booked a Koh Tao dive trip, this is your sign.
