PADI Discover Scuba Diving in Koh Tao - half day and two dives

Koh Tao’s reputation as Thailand’s cheapest place to try scuba holds up, and this half-day Discover Scuba session at Blue Diamond Resort is a sensible way in. Two guided dives under a PADI instructor around Koh Nang Yuan, no prior experience required. Six hours total including kit-up, briefing and surface time between dives.

The morning starts with a land-based briefing covering how the equipment works, hand signals, and the basic skills you’ll practise in shallow water (mask clearing, regulator recovery). You then head out to the dive sites around Koh Nang Yuan, the three-island sandbar just off Koh Tao’s north-west coast, where gentle sloping reefs make it an ideal beginner setting. Each dive runs around 30 minutes under direct instructor supervision, with coral reef, reef fish and the occasional turtle on the list of what you might see. Snorkelling gear is included for surface time, and snacks, coffee and tea are served on the boat.

No certification or swim-test here, so this is strictly an introduction, not a course. You need basic swimming confidence and a clear medical statement (pregnancy, recent surgery or certain conditions rule you out). Lunch isn’t included; bring cash for food and tips. If you enjoy it, the same shop runs the full Open Water course. Fine weather most of the year except November, when monsoon closes some dive sites. Koh Nang Yuan requires a 250 THB private-island entrance fee not included here; check in advance. Group size isn’t specified in the listing but tends to be small for Discover Scuba formats. The 4.6 average across 76 reviews is standard for entry-level dive operations on Koh Tao. If you do get hooked, the shop also runs the three-day PADI Open Water course at competitive rates.
