Overview

The Open Water course is where most divers start, and Koh Tao is one of the best places on the planet to do it. Warm water, good visibility, calm beginner-friendly dive sites, and an island that has been training divers seriously since the 1990s. The conditions here genuinely make learning easier.

At Goodtime, we run a maximum of four students per instructor. That’s a deliberate choice, not a marketing line. More than four and the dynamic changes — you spend more time waiting and less time actually diving.

The course runs over 2.5 days. Day one is theory and confined water. Days two and three are your four open water dives, starting at 12 metres and progressing to 18 metres as your confidence builds.

Koh Tao’s beginner dive sites are genuinely good diving, not just training grounds. Japanese Gardens has soft corals, resident turtles, and enough marine life to keep you distracted between skills. White Rock regularly has reef sharks cruising the shallower sections.

Course Highlights

Max 4 per instructor

More time in the water with your instructor, less time waiting around.

Shallow water sessions to start

Your first skills happen in the pool or a sheltered bay — calm, controlled, and at your own pace. There's no pressure to progress until you're ready.

Real diving from day one

Our beginner sites have coral, marine life, and visibility that reminds you why diving is worth doing.

Later departures, quieter sites

We time our trips to avoid the morning rush at popular dive sites.

Marine Life We May See

Marine life sightings depend on season, conditions, and a bit of luck. These are species commonly spotted at the sites we use for this course, but nothing in the ocean is guaranteed. That's part of what makes it interesting.

    We select sites based on conditions, your group's progression, and how busy the reef is that day. These are the sites we typically use for Open Water training.
