9 Koh Tao Dive Shops to Compare

Each entry below is a short decision note, and the linked profile holds the detail. We quote no course rates because every shop sets and updates its own. Prices and hours checked November 2026: current rates sit on each shop's own site.

1. Ban's Diving Resort

Ban's Diving Resort suits divers who like training and a bed from one operator. Open its profile for the course list, location and room details before you compare quotes. Ask whether accommodation is bundled into course pricing and what happens to the room if weather delays a boat.

A first-timer who wants everything arranged in one booking is the natural fit. Skip it if you already have a room on Sairee Beach and only want a few fun dives.

2. Sairee Cottage Diving

Sairee Cottage Diving is a Sairee Beach name that came up repeatedly in diver recommendations. A 2019 forum reply described a separate fun-diver boat that left around 8 AM and ran three tanks. Boat routines change, so ask the shop which boat and schedule your dates would use.

Certified divers staying on Sairee Beach who want a full day on the water should read this profile first. Skip it if you want a short half-day trip rather than a long boat day.

3. Big Blue Diving

Big Blue Diving works from Sairee Beach and is a common pick for fun divers. A 2019 forum reply mentioned a separate boat for fun divers, which can reach more sites than a beginner-course boat. Ask which sites your dates would cover and whether Sail Rock appears on the posted weekly schedule.

Experienced divers who want variety beyond the shallow training reefs get the most from it. Skip it if you need a first-ever Discover Scuba session and want a quiet, beginner-only boat.

4. Black Turtle Diving

Black Turtle Diving belongs on your list if you are weighing several mid-sized schools against each other. Start with its profile, then ask for group size, instructor name and boat departure time in writing. Those three answers separate shops more reliably than a brochure does.

Divers who value knowing exactly who will teach them should press on instructor continuity. Skip it if you have already settled on a specific beach and this shop sits far from your base.

5. Crystal Dive

Crystal Dive publishes its own course information on its official site. Use that site and the profile together to line up course levels, start dates and accommodation options. Ask how many students share an instructor on open-water days.

Learners who want a full path from first breath to higher certificates should shortlist it. Skip it if you need a same-day walk-in trip with no advance planning.

6. Simple Life Divers

Simple Life Divers is the entry to read if you prefer a smaller-feeling operation. Check its profile for course focus and location before you assume anything about group size. Ask directly how many divers go on each boat and who carries out the briefing.

Solo travelers who want to meet people and not be one of many students should ask about group makeup. Skip it if you want the widest possible choice of daily departures.

7. DPM Diving

DPM Diving is worth opening when you are thinking beyond a single course. Look at its profile for Rescue, Divemaster and instructor-track information. Ask how many Divemaster candidates train at a time and how much real dive guiding you would get.

Career-minded divers weighing Divemaster should compare its program against two other shops. Skip it if you only have a few free days and want relaxed fun dives.

8. Roctopus

Roctopus rounds out the shortlist for readers who want a different style of shop. Read its profile for the course range and location, then compare it with the Sairee Beach options above. Ask about boat comfort, because you spend most of each dive day on deck.

Divers who prefer to judge a shop on conversation, not marketing, should visit in person. Skip it if you need a firm schedule locked in before you leave home.

9. Davy Jones' Locker

Davy Jones' Locker is the last profile to open when you compare area by area. Check where it sits against your accommodation, since a short walk to the shop makes early boats easier. Ask what is included: equipment hire, e-learning materials and any logbook or certification fees.

Budget-conscious divers should request a written, itemized quote. Skip it if you want one operator to handle your stay and your diving together.

How to Choose Among Koh Tao Dive Shops

Price alone tells you little, so compare shops on the same questions. Ask about group size per instructor, boat type and departure times, course language and equipment age. Ask how emergencies are handled, and whether the shop runs conservation work such as reef cleanups. Confirm the certification agency, and use the SSI dive center locator to check an SSI affiliation. Send the same questions to three shops and compare the written answers.

Which Diver Are You?

We'd match diver type to shop type first, then narrow by beach. Use this grid as a starting point.

Costs and What Drives Them

We list no rates here because Koh Tao shops set their own and change them often. Cost moves with five factors: course versus fun dive, certification level, equipment rental, e-learning fees and accommodation bundles. Ask each shop for one itemized quote covering all five. A low headline price that leaves out gear or certification fees is not a real comparison.

Planning Your Time: Courses and Boat Schedules

Shops commonly advertise Open Water as a 3-day course when you finish e-learning before arrival. A 2-day Rescue course is also advertised on the island. Morning boats often leave near 6:00 AM or 7:00 AM and afternoon boats near noon. Each shop posts its own times. Leave a buffer day between your last dive and your flight, and read DAN flying-after-diving guidance for the surface interval.

Where to Stay and Getting Around

Sairee Beach is the base most fun divers choose, and two of our shops, Big Blue and Sairee Cottage, are tied to it. Mae Haad and Chalok Baan Kao are the other two areas worth weighing. Pick your shop first, then book accommodation within walking distance of its meeting point. Early boats make a long commute a daily cost. If a shop bundles a room with your course, ask what happens if you extend.

Dive Sites to Ask About

PADI lists 29 dive sites around Koh Tao. Its tallies are 22 reef, 14 ocean and 7 pinnacle sites, and those categories overlap, so do not add them up. Ask each shop which sites your boat would visit on your dates. Sail Rock runs on posted weekly schedules at many shops, so confirm the day for your season. One forum diver said the Andaman Sea side of Thailand has better biodiversity, while Koh Tao suits easy, shallow dives.

Mistakes to Avoid When Booking

Do not book on price alone. Do not skip asking for the instructor's name and the maximum group size. Do not assume accommodation is included. Do not leave Sail Rock or other special trips unconfirmed until you arrive. Do not fly too soon after your last dive. Do not accept badges or ratings as proof; check the certification agency's own locator.
