Scuba Diving Koh Tao — Island Dive Guide

Why Koh Tao?

One of the world's best places to learn — and keep diving.

Koh Tao is a scuba diving magnet for good reason: warm water, dozens of sites, and reefs that suit every level from first-time try-scuba guests to experienced deep-dive enthusiasts. The east coast of the Gulf stays calm for most of the year, and the underwater visibility can stretch to 30 metres on the best days.

The difference with Dive Wishes & More is that the diving is not outsourced. We have our own SSI instructors, our own speedboats, and a flexible, private approach. You are not joining a group shop; you are diving with a team that knows the sites, the tides and the crowds.

“Private boat · private guide · quiet dive sites.”

The private advantage

Why a private dive boat changes the experience.

Most group dive boats around Koh Tao leave early, follow the same daily schedule, and visit the same famous sites at the same time. That is how queues at moorings happen.

We leave later, read the water from the deck, and change the plan in real time. If a site is busy, we go elsewhere. If the current is better on the other side of a pinnacle, we move there. The boat is yours, the guide is yours, and the schedule answers only to you.

Top dive sites

The best of Koh Tao island diving.

From beginner-friendly bays to deep pinnacles famous for whale sharks, these are the sites we visit most often.

18 – 40 m · Open Water / Advanced

Sail Rock

The region's most famous pinnacle

Dramatic swim-through chimney
Schools of trevally, barracuda and batfish
Whale shark encounters between March and May
Located between Koh Tao and Koh Phangan

Private angle: Because we reach Sail Rock on our own private speedboat, we can time the trip to avoid the day-trip fleets and descend the chimney without a queue of fins behind you.

14 – 36 m · Open Water / Advanced

Chumphon Pinnacle

Big-fish country

Granite pinnacles rising from the sand
Giant groupers, batfish and chevron barracuda
Best early-morning visibility
Another whale shark hotspot

Private angle: A private boat means we can leave before the group boats and be on the pinnacle with the fish — not the crowd — or stay later when the water empties out.

6 – 22 m · All levels

White Rock

Colorful, easy and close to home

Two sister rocks covered in soft coral
Turtles, moray eels, stingrays and reef fish
Great for snorkelers and try-scuba guests
Just a short boat ride from Shark Bay

Private angle: White Rock is beautiful but can get busy. From our boat we can see if the mooring is stacked; if it is, we simply drift over to a quieter corner or switch to another site.

12 – 30 m · Open Water / Advanced

Green Rock

Sail Rock's quieter neighbor

Swim-throughs, small caverns and overhangs
Less traffic than White Rock
Good macro life: nudibranchs, shrimp, boxfish
Fun for confident beginners too

Private angle: Green Rock is our favourite backup plan: when the main sites are crowded, we head here and almost always have the water to ourselves.

10 – 25 m · All levels

Shark Island

Pelagics and reef walls

Named after the island's shark-fin silhouette, not sharks
Regular visits from reef sharks and eagle rays
Steep wall on one side, gentle reef on the other
Clear water on the south side of Koh Tao

Private angle: With a private boat you can circle the whole island and pick the side with the best current and visibility — no fixed group itinerary.

18 – 40 m · Advanced / Experienced

Southwest Pinnacle

Advanced, exposed and rewarding

Deep granite pinnacles and strong currents
Seasonal whale sharks and bull sharks
Big pelagic action away from the busy bays
Best on calm days with good surface conditions

Private angle: Southwest needs a fast, seaworthy boat and local knowledge. Our private speedboat gets you there comfortably and lets the guide read the current before you jump in.

Try scuba & courses

Never dived? Koh Tao is the perfect place to start.

Diving FAQ

Common questions about Koh Tao island diving.

What is the best time for scuba diving Koh Tao?+

Koh Tao island diving is year-round. Visibility is usually best from March to October, and whale sharks are most commonly seen around Sail Rock and Chumphon Pinnacle between March and May.

Do I need a diving certification to join?+

No. Certified divers can book fun dives, and beginners can try scuba diving with a private SSI instructor. Open Water and Advanced Adventurer courses are also available.

Why book a private dive boat instead of a shop?+

A private boat gives you flexible timing, your own guide, and the freedom to move away from busy sites. If White Rock is crowded, we can switch to Green Rock or another quiet spot on the same trip.
