You step aboard before sunrise, the boat nudging away from Koh Samui while the limestone silhouettes of Koh Tao grow sharper on the horizon. Sea-slick air fills your lungs; the engine’s low thrum is a promise of movement. By midmorning you’re anchored in a shallow bay where the water is so clear you can see the reef plate fall away in layers of green and blue.

Koh Tao shifted from a small fishing and turtle-harvesting island to a global dive-training center in the late 20th century, driven by affordable courses and clear, sheltered sites.
Conservation
Reef health is fragile: operators encourage buoyancy skills, no-touch policies and reef-safe products to minimize damage and support local marine-protection efforts.

Do the pool session first
Arrive early to try regulator breathing in a pool — it makes the open-water dives smoother and less stressful.
No flying after diving
Plan flights for at least 48 hours after your last dive to avoid decompression risk.
Protect reefs
Use reef-safe sunscreen and avoid touching coral; instructors will brief you on buoyancy and fin placement.
Bring seasickness remedies
If you’re prone to motion sickness, take medication before boarding and sit mid-boat where movement is gentlest.
Reef-safe sunscreen
Protects your skin and nearby coral while spending long periods on deck and in shallow water.
