Experience SSI’s Basic Diver program on Koh Tao: a full‑day introduction that starts with classroom theory, leads to a supervised shallow dive (0–5 m), and offers an optional second dive to 12 m. Ideal for first‑time divers with moderate fitness.

You step off the longtail into warm, honeyed water and the surface breaks into glittering chunks under a wide Gulf sky. An SSI instructor checks your gear on the boat, voices steady against the slap of wake; the day begins with a 40‑minute classroom primer on basic dive theory, then moves quickly to the shallow reef where the first breaths underwater are taken.

History
Koh Tao transformed in recent decades from a sparsely inhabited fishing island to an international dive training center, driven by easy access in the Gulf of Thailand.
Conservation
Choose operators who emphasize buoyancy control and reef‑safe products; coral on Koh Tao is recovering but remains vulnerable to careless contact and anchor damage.

Bring your passport info
You’ll need passport details for booking and check‑in—keep a photocopy or digital photo accessible.
Protect against sun and heat
Apply reef‑safe sunscreen before the boat leaves and cover up between briefings to avoid sunburn.
Prep for equalization
Practice jaw and ear equalization on land; shallower training dives still require active equalizing.
Manage seasickness proactively
Take anti‑nausea medication before boarding if you’re prone to motion sickness—boat rides and swell are common.
Swimsuit and quick‑dry shorts
Comfortable under wetsuit or alone for surface time and lessons.
