No certification needed. A PADI instructor takes you from your first breath underwater to two real ocean dives on Koh Tao's reefs — all in one day. Want just one dive? 2,600 THB.
Real attention, real safety. Not a 12-person cattle dive.
We don't share boats with other shops, so the schedule actually runs on time.
Same standards as the biggest shops on the island, with a fraction of the people.

"There are so many dive schools in Koh Tao and this one is definitely the best. The friendliest instructor ever — best day of our trip!"

"Our instructors Chris and Noah were incredible — kind, helpful, funny and patient. We owe a huge thanks to Siam Scuba, easily one of the nicest dive shops in Koh Tao."

"Fantastic experience. The staff were incredibly kind and welcoming. Small group meant I got tons of personal attention. Certified in 4 days and already planning my next dive."

We keep groups small so the schedule actually runs on time. You're back at the shop by late afternoon, in time for sunset on the beach.
