January 2025 | Alex h

Amazing diving school thanks to Meg and Dave. They were really helpful and also really funny and made the whole experience really fantastic to be honest. If you’re wondering where to go definitely go to this school and ask for Dave or Meg to be your instructor, you can’t go wrong.

Dec 2024 | Lotte

Out of all the places to do your open water course in Koh Tao, which are a lot, I am so glad I got to do mine at Simple Life Divers, with Dave as my instructor. During this three-day course you thoroughly learn all the skills that are needed for open water diving. Dave’s patience and laid-back way of teaching really amplified our confidence, which made the experience in general a very positive one. A welcoming community during the dives and outside of it, as we got to join them for Christmas dinner as well. When in Koh Tao, I’d definitely recommend starting or continuing diving as the diving sites are absolutely stunning and the crew of Simple Life Divers so supportive, an unbeatable combination.

Dec 2024 | Sean V
There’s an overwhelming number of options when choosing a diving school on Koh Tao, but these guys were seriously awesome! Dave was an amazing instructor with a perfect blend of fun but knowledgeable. The group size was also fantastic. Can’t recommend enough!
Nov 2024 | Anna M
Nailed my OWD course with Dave and I couldn’t be happier about it. Classes were focused on mastering practical skills with a lot of advice, attention, comfort and care. Thanks for all the support and encouragement provided – I have felt so safe and seen, Dave and Nathan were always there for me whenever I had any doubts or needed extra assistance. Proud to be a part of divers’ community since today!

I did my Open Water and Advanced Scuba Diving Certifications back-to-back with Dave as my instructor. The whole time he made me feel super safe and confident in everything I was doing, whilst also being such a good laugh. I learnt so much from him, he’s so knowledgeable in the industry, and he really tried to impart as much of that knowledge as possible. He made the experience so enjoyable for the group.

It’s quite nerve-wracking being a new diver, but all the Simple Life Divers are so friendly and helpful whether it’s in the dive shop or out on the water. I’d like to give a huge shout-out to Billy, in particular, who helped out on both my courses.

I really recommend Simple Life as the dive shop of choice in Koh Tao.

March 2025 | Sophie D

Had a great time with Dave doing my open water course. Never dived before, everyone was very nice and welcoming and made me feel comfortable in the water. Very relaxed, great dive sites, highly recommend!

March 2025 | Dreamer30663427746

My Instructor Dave was funny and knowledgable as always, did my Open water diver last year and came back this time to do the Advanced course. Cant do much wrong booking here.

March 2025 | Albert C

Just finished my open water qualification with Simple Life Divers! – My instructor Dave Webber is a class act. Great banter, very knowledgable and easy to learn from! I originally discovered Simple Life via word of mouth (friend at home) and can safely say anyone who wants to learn scuba on Koh Tao this is the only place you need to go to.

March 2025 | Olivia W

The experience was nothing short of phenomenal, not just because of the beautiful reefs of Koh Tao, but our instructors Dave and Jake. Both created a super safe space for learning and asking questions. Dave’s delivery of the course was beyond expectations and supplemented by his wealth of experience, having been diving for 32 years all over the world. He prioritizes safety in his teaching and during training dives, frequently checking in with each student and taking the time to thoroughly explain tough concepts or key points. I’d come all the way back to Koh Tao from Canada to do my advanced level cert just because of Dave, he’s an absolute legend.

March 2025 | Tessa L

With so many dive schools on the island, I took my time and visited six different ones to find the perfect fit. I wanted not just a professional and safe diving school, but also a place where I would feel comfortable and supported.

What made this experience truly special was the way Dave and Jake shared their passion for diving with such patience and enthusiasm. They created a relaxed and supportive learning environment where I felt completely safe and confident in the water. Taking my first breath underwater and floating among the stunning marine life of Koh Tao was absolutely magical.

Frequently asked questions

Sail Rock is renowned for its diverse underwater topography, offering depths ranging from shallow areas around 5 meters to deeper sections reaching up to 40 meters. While the site is accessible to Open Water certified divers, it’s essential to be comfortable with open-water conditions and potential currents. Beginners should dive with experienced guides and remain within their certification limits to ensure safety and enjoyment.

The “Chimney” is a vertical swim-through tunnel within Sail Rock, starting at approximately 18 meters and exiting around 6 meters. It’s a highlight for many divers, offering a unique experience as you ascend through the rock formation. Divers attempting the Chimney should have good buoyancy control and be comfortable in confined spaces. Always follow your guide’s instructions when navigating this feature.

Sail Rock boasts a rich biodiversity. Divers often encounter large schools of barracuda, trevally, and batfish. The site is also home to groupers, moray eels, and various species of nudibranchs. During certain times of the year, there’s a chance to spot whale sharks, making it a sought-after destination for marine enthusiasts.

The Sail Rock excursion is a full-day trip. We depart from Koh Tao early in the morning and return by mid-afternoon. The boat journey to Sail Rock takes approximately 90 minutes each way, during which you’ll enjoy meals and refreshments onboard.

Absolutely. We provide a light breakfast before departure, lunch between dives, and snacks and drinks throughout the day. If you have specific dietary requirements, please inform us in advance, and we’ll do our best to accommodate you.

Ensure you’re well-rested and hydrated before the trip. Bring your certification card, logbook, swimwear, towel, sunscreen, and any personal items you might need. If you haven’t dived recently, consider a refresher dive to reacquaint yourself with diving skills and equipment.

Yes, all necessary scuba equipment is included in the trip. This comprises your BCD, regulator, wetsuit, mask, fins, tank, and weights. If you have personal gear, you’re welcome to use it, and our team will assist with setup and checks.

Yes, we offer Enriched Air Nitrox for certified divers. Diving with Nitrox can extend your bottom time and reduce nitrogen absorption, especially beneficial for deeper dives like those at Sail Rock. Please let us know in advance if you’d like to use Nitrox, as it requires additional preparation.

Booking your Sail Rock dive adventure is straightforward. You can reserve your spot directly through our website, contact us via email or phone, or visit our dive shop in person on Koh Tao. We recommend booking in advance to secure your place, especially during peak seasons.

Sail Rock is diveable year-round, but conditions are generally optimal between May and September. During this period, the Gulf of Thailand experiences calmer seas and better visibility, enhancing the overall diving experience. However, marine life sightings, including whale sharks, can occur outside this window, so it’s always a good idea to check with local dive centers for current conditions.
