Too many beginners for seasoned divers
I thought the booking process was great and commutation was excellent but throwing advanced divers in a boat filled with beginners and trainees at a premium price was disappointing. I was paired with someone who rarely dives and was worried more about her lack of being able to stay buoyant or conserve air for me to be able to relax and explore but she couldn't keep up with me as she slapped her arms instead of using her fins. I would look around and she'd be gone so I'd look up and she'd be somewhere above me. The second dive she ran out of air so the dive was cut short twice. First dive, I lost her and the group (it became confusing with so many people) and the second my buddy ran out of air. She was a sweetheart but there should be a separate boat for seasoned divers. Our dive master skipped the safety stops which I was nith thrilled with. I understand we had "situations" but once everyone was "OK" I expected to do safety stop at the line. Luckily we didn't go very deep and both dives were around 30 minutes. NOTE: We had to skip "Sail Rock" for low visibility, so the bright side was I saw Koh Tao and Nang Yuan. I understand a business wants to make money but I would not use any of the major dive operators as they're all thrown on the same boat (twenty people).

Great dive school and great for younger diversrs.
My 13 year old son did his open water dive course at the Dive Academy, he had a great time and felt very safe under the instruction of their Dive Instructor Alex who I highly recommend not just for adults but also kids. The pace was ideal and we were looked after from start to finish. The groups were small to allow for much more personal attention. I also came along for a Refresher dive and dive tour to Koh Tao and Sail Rock. Both were very well organised and the dives were all driven by the wants of the divers themselves in coordination with their Dive Master. The dive masters and instructors went out of their way to accommodate us and the highlight for us were the dives with Alex especially at Sail Rock.

Incredible team, diving with the dive academy is a must do on your trip to Koh Samui
I had the absolute pleasure of getting my PADI open water certificate with the Dive Academy and I cannot recommend them enough. A fantastic team with great vibes and a really great set up. I was lucky enough to have Michael as my instructor and he was the best. Very professional and was incredibly patient with me as I did things in my own pace, he always made sure I was comfortable and he really made my experience special! The Dive Academy has great dive sites, Koh Samui is absolutely beautiful so please make sure if you come to visit you book in with TDA to do a discover scuba or snorkel or even get your PADI open water! I’ll definitely be coming back again for another dive 🤙

Check if you need a doctor's note!
I can't comment on the trip as I wasn't able to go but this is to notify others to make sure they ask if a doctor's note is required. I wasn't able to go on the trip because I wasn't given enough notice (less than 24 hours) to get a doctor's note. When I spoke to them they said I could sign a liability form but then revoked this the evening before. The medication I take has not been flagged to me before as a potential issue without getting a doctor's note so I assumed all would be fine. They were very apologetic and it sounded like a temporary staff education matter.

Why this scores 75
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Diving Tour for Certified Divers: Sail Rock or Koh Tao: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Koh Samui.
How much does Diving Tour for Certified Divers: Sail Rock or Koh Tao cost?
+
Prices start at $159 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Koh Samui usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Diving Tour for Certified Divers: Sail Rock or Koh Tao take?
+
Plan for about 7 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Koh Samui is not rushed.
Is Diving Tour for Certified Divers: Sail Rock or Koh Tao worth it?
+
It holds an Outty Ranking of 75 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.6/5 across 76 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Koh Samui, and how flexible the cancellation terms are.
Can I cancel or reschedule Diving Tour for Certified Divers: Sail Rock or Koh Tao?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Diving Tour for Certified Divers: Sail Rock or Koh Tao suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 7-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Diving Tour for Certified Divers: Sail Rock or Koh Tao?
+
Around 27 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Koh Samui can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Koh Samui and add a light layer if any part of the 7-hour experience runs outdoors or after sunset.
Where does Diving Tour for Certified Divers: Sail Rock or Koh Tao start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Koh Samui within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Koh Samui?
+
On Outty we rank every Koh Samui experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Angthong National Marine Park VIP Small Group Tour, Cooking Class in Koh Samui with Micro Organic Garden, Half Day Elephant Home Sanctuary in Samui. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Koh Samui?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Koh Samui?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
