Best Dive School in Koh Phangan: The 3 I Used
Koh Phangan might not have the same reputation for diving as its neighbour Koh Tao, but that doesn’t mean the diving is any worse.
In fact, the best dive site in this bit of the Gulf of Thailand, Sail Rock (the rock, not the dive school), is actually closer to Koh Phangan than it is to Tao.
If you want to get your PADI ticket or spend a day underwater without joining the Koh Tao production line, Koh Phangan is a very good place to do it. I used all three schools in this guide, although one is the clear winner for me.

The Short Version
Sail Rock Divers is my pick. I did my Open Water course there, then went back for four more dives at Sail Rock, so this is not a recommendation assembled from three nice-looking websites.
It has the proper training setup, small course groups and its own boat running daily to the island’s headline dive site. Chaloklum Diving is the smaller village alternative; Haad Yao Divers is the convenient west-coast option. Both were good, but Sail Rock is the one I would book again.
All three are current PADI five-star centres. Prices above were checked against the operators’ own sites in August 2026 and include equipment; the boat-day prices also include food and drinks. Ask what is running on your date before paying, because weather still gets the final vote.
First, How Does Koh Phangan Compare to Koh Tao?
Now, this is the big question.
I’ve spent a couple of weeks on both Koh Tao and Koh Phangan now (across two separate trips to Thailand).
The simple answer is the best diving you’ll find is at Sail Rock (the rock – not the dive school). But companies on both islands run trips there almost daily. So, for accessing Sail Rock itself, it doesn’t really matter.
Koh Tao has more dive companies and schools. Has cheaper pricing (mostly because there are so many schools competing for the same backpackers) and has far more local dive sites around the island.
Koh Phangan, on the other hand, doesn’t have as many good sites around the island itself, but it is closer to the offshore sites like Sail Rock. The boat days felt quieter too.
What’s the Diving Like in Koh Phangan?
PADI lists 5 dive sites around Koh Phangan: 3 reef dives, 2 beach dives and 2 cave dives.
The categories overlap – one site can count as both a reef and cave dive before anyone starts checking my maths.
Koh Phangan’s dive scene is smaller. Sail Rock is undoubtedly the crown jewel, then you have local reef dives around places like Koh Ma and longer trips towards Ang Thong or Koh Tao. You do not get Tao’s endless menu, but for a few days or a week there is plenty to keep you busy.
The diving felt a little more raw and less commercialised to me. Fewer boats, fewer groups piling into the same patch of water, and more time to enjoy what was actually down there.
The trade-off is variety. If you’re staying long-term, you might find yourself repeating sites. If you are here for a course and a few fun dives, I don’t think that matters much.
Diving in Koh Tao
PADI lists 26 dive sites around Koh Tao: 21 reef dives, 14 ocean dives and 6 pinnacle dives.
Koh Tao has variety. There’s no question that it is the more developed dive hub. I’ve had some great dives at places like Chumphon Pinnacle and Southwest Pinnacle.
But the thing with Koh Tao is the crowds. Sometimes it felt like I was diving in a line, with boat after boat dropping divers into the same spot. It’s hard to fully appreciate a coral reef when you’re surrounded by a dozen other divers kicking up sand.
The marine life is still great – turtles, rays, reef sharks and loads of fish – but I found it less intimate. Don’t get me wrong, I had some magical moments there, especially night dives at White Rock, but Koh Tao’s sheer popularity has taken away some of the magic for me.
The Verdict: Which Island Has Better Diving?
I found Koh Phangan’s diving to be more up my alley.
This is probably more of a comment about the experience out of the water than in it. But diving in Koh Phangan felt less rushed. A bit more chilled, and I didn’t feel like I was part of a diving conveyor belt, which is sometimes the case in Koh Tao.
For me, that makes all the difference.
If you want variety, loads of sites and a bustling dive scene with plenty of social opportunities, Koh Tao is your spot. But if you’re after a more personal experience with fewer crowds – and a nicer island to come home to when you take the tank off – Koh Phangan takes the crown.
Why Sail Rock Is the Dive to Book
We did four dives at Sail Rock with Sail Rock Divers, and it genuinely lived up to the hype. The visibility was excellent, and within the first few minutes we encountered a massive school of trevally swirling around the pinnacle.
The rock sticks out of deep open water and acts like a fish magnet. Barracuda, batfish, groupers and huge schools of smaller fish gather around it; whale sharks do pass through, but treat that as a lottery ticket rather than part of the booking.
The chimney was my highlight. It is a vertical swim-through that you enter at about 18 metres and rise through before popping out around 8 metres. Very cool. Also an excellent moment to discover whether your buoyancy is actually as tidy as you thought it was..
Sail Rock is suitable for Open Water divers, but the current can change and not every diver should enter the chimney. Tell the school your certification, number of logged dives and last dive date honestly, then let the guide make the call on the day.
1. Sail Rock Divers – My Overall Pick
I did my Open Water course with Sail Rock Divers, so this is the recommendation with the most skin in the game. Your first course is not the time to pick a school because its logo looks nice or it saved you 400 baht. You want an instructor who has time to notice when you are pretending to understand something.
Sail Rock has a dedicated pool rather than trying to teach the confined-water skills wherever the sea happens to be calm that morning. The current course takes three days: one in the pool, then two days completing four open-water dives. Groups are capped at four students per instructor.
The Open Water course currently costs THB 12,900, including eLearning, equipment, a dive computer, certification and breakfast and lunch on the boat days. That is everything important bundled together, without discovering halfway through that breathing underwater has optional extras. Check the current course details with Sail Rock Divers.
I later went back to dive with them again. Our briefings were clear, the boat day ran properly and the post-dive food appeared exactly when everyone had reached that strange ravenous stage caused by doing almost nothing except breathe and kick your legs.
If you are already certified, the daily Sail Rock trip is THB 3,200 for two dives, with equipment, breakfast, lunch and drinks included. You meet at 7:15am, leave Chaloklum around 8am and normally return between 1:30pm and 2pm. You can pre-book the Sail Rock fun dive through Klook, or check the latest trip details directly with Sail Rock Divers.
2. Chaloklum Diving – The Village Alternative
Chaloklum Diving is the smaller, more old-school alternative in the same village. After booking with them, what struck me was how personal the whole setup felt. The whole operation felt more like a community than a business, and properly part of Chaloklum rather than a resort that happened to sell dive courses.
The team was attentive, especially with the more nervous divers around us, and they also keep groups small. I liked them. They just are not the school where I actually learned, which makes Sail Rock the easier first recommendation.
Chaloklum’s PADI Open Water course currently costs THB 13,200 and takes three or four days, including equipment, learning materials and certification. A Discover Scuba beach dive is THB 2,000; a two-dive beginner boat day is THB 4,100. Check the current course list with Chaloklum Diving.
Tip: Stay around Chaloklum while you train. It saves a daily scooter trip across the island, and you can walk down for seafood or an easy dinner once your brain is full of dive tables and hand signals.
3. Haad Yao Divers – The West-Coast Option
I joined Haad Yao Divers for a fun dive at Koh Ma, the little island connected to Koh Phangan by the sandbar at Mae Haad. It was an easy, low-stress dive and the team took their time matching people to the right level.
The reef did not have the same ridiculous density of fish as Sail Rock, but that is not really the point. A local dive is useful if you are nervous, rusty, short on time or want to get comfortable again before heading offshore. Haad Yao also includes pickup from the west-coast zone, which is a meaningful perk if that is where you are staying.
Two-dive trips currently run from THB 3,400 to THB 4,200 depending on the site, including equipment, meals, drinks, marine-park fees and insurance. Groups are capped at four divers per guide. See the current options or message Haad Yao Divers.
When to Dive Koh Phangan
You can dive around Koh Phangan year-round, with warm water sitting around 28-31C. Conditions are often clearest from roughly March through September; the rougher Gulf monsoon weather usually lands later in the year and can reduce visibility or cancel offshore trips.
Do not build a Thailand itinerary around a promised whale shark. Pick a decent weather window, book a school you trust and consider the big fish a bonus. The trevally, barracuda and sheer wall of life around Sail Rock are worth the trip without one.
Before You Book
Tell the school when you last dived. Sail Rock Divers recommends a THB 500 refresher if you have been out of the water for a year or more; Haad Yao can also arrange one. It is a much better use of money than spending the first dive trying to remember which hose does what.
Also check your travel insurance properly. Plenty of policies cover ordinary scuba only to a stated depth, only when you hold the right certification, or not at all. Scooter exclusions are another issue on Koh Phangan, because naturally the two activities most travellers do here are the two hiding in the small print.
Not ready to commit to the full Open Water course? Book a Discover Scuba day with Sail Rock Divers instead. It is the sensible try-before-you-buy option, and rather cheaper than discovering on day one of a course that breathing through a regulator is not your idea of fun.
Make Chaloklum Your Base
I would stay in the north for the diving rather than scooter across the island half-asleep at 7am. Malibu Beach Bungalows gives you the useful bit of Chaloklum village plus the much nicer sand at Malibu Beach, and it puts all three schools within easy reach.
After the boat, get dinner at LEO Thai Food or wander the waterfront until somewhere smells good. That is a better end to a dive day than rushing straight back to Haad Rin, and honestly a better version of Koh Phangan full stop.
Thailand Travel Cheatsheet
🚑 Should I buy travel insurance for Thailand?
100% YES! — Thailand has some of the best healthcare in Asia (and the world) but it’s not free for tourists.. well – it is and it isn’t.
The thai government has extended it’s tourist healthcare policy for ‘up to $15,000 medical cover’ for tourist accidents, up until the end of 2024. That will cover you for small dings, but won’t be enough for anything major.
If you DO get insurance, also be aware many policies won’t cover adventure activities like diving, or motorcylce riding (as it’s a high risk activity)!
(that’s right, check the t&c’s on your complimentary credit card insurance)
I highly recommend World Nomads as you can get specific add-ons for diving, or motorcyle riding (Which is one of the main reasons I went to Thailand!)
🎫 Do I need a visa for Thailand?
Probably not — 93 countries are entitled to visa exemption for the purpose of tourism for up to 60 days.
However, some other countries do need a pre-approved eVisa or a Visa on Arrival (VoA) (check here!). These start at 2,000 THB for 15 days and prices go up from there!
💉Do I need any vaccinations for Thailand?
YES! Make sure you are up-to-date with all your vaccines. Common travel vaccines include Hep A/B + Typhoid, and Diphtheria + Tetanus.
Thailand is commited to rabies eradication, though there are still a few cases each year. Generally the risk in Thailand is seen as extremely low.
As always, talk to your GP or specialised travel doctor a few weeks BEFORE you leave.
💸How do you pay for things in Thailand?
Cash is king in Thailand, but electronic payments have come a long way in the 5 years since I last visitied. You’ll want to get some folding tender out from an ATM when you land.
Generally street food stalls, mum-and-dad shops and small businesses will only take cash, whereas larger bars, resturants, hotels and resorts will be perfectly happy taking card.
I personally use a Wise debit card for all my international money needs as they only convert the funds when you make payment, plus they offer a much better spread (margin on the true exchange rate) than the banks do. They work in all the Thai ATMs I tried although the ATMs to charge a fee of 220 baht to withdraw.
→ Get the Wise card I use — set it up before you fly so it’s ready to tap the moment you land.
🚌 What’s the public transport like in Thailand?
In short. FANTASTIC
There is a good network inter-city busses in Thailand and travel this way is very cheap and very comfortable. Domestic flight are also very affordable.
The best part about Thailand is booking agencies all work together to offer combined tickets that will get you exactly where you want to go. For example, we got a hotel transfer to the ferry terminal -> Ferry to Surat Thani -> Bus to Krabi -> Mini Van tranfer to Ao Nang all on the same booking. So easy!!
📲 How do I get internet/data/wifi in Thailand?
This one needs a whole nother article, but the short version is prepaid SIM cards are cheap and availible to tourists and locals alike (You don’t need a pricey tourst SIM!)
Don’t get tricked into getting a tourist SIM at the airport. Go to any 7-Eleven store and buy a local pre-paid SIM card which is cheaper, faster and gives you more data.
NB: Make sure to bring your passport for ID verification!
Another option is an Airalo eSIM. This is a little more expensive but works from the moment you land is is SOOOOO much easier than the in person verification process required for a local sim.
TIP: Grab your Airalo eSIM before you fly and you’ll have data the moment you land, with no hunting for a SIM kiosk.
✈️ What’s the best site to buy flights to Thailand?
For finding cheap flights, I recommend Skyscanner. Once you find the flight you’re looking for, I’d then suggest booking directly with the carrier (even if it costs a few $$ more than with one of the agreggators/agencies).
💧Can you drink the water in Thailand?
Safest not to — tap water in Thailand may be OK (the locals drink it) but is generally untreated and not reccommended for tourists. Purchase bottled water for drinking and teeth brushing, or get water purification tablets.
I always use these Aquatabs and also recommend a Brita Water Bottle for as some of the tab water wasn’t exactly clear either!
