Thailand has some great dive spots and while some of them may not be as incredible and colourful as they once were, the reasonable prices and wide availability of dive centres will always keep me coming back for more diving. As far as I know Koh Tao still claims to be one of the cheapest places to do your Open Water certification, which is where I did my first diving certificate 4 years ago, and it’s been an obsession ever since. I have over 70 dives and most of them have taken place in Thailand. I still have a few more dive places to try out in the near future though.
While I’ve dived off many islands and beaches around Thailand the following are my top dive sites that I have returned back to many times:
Diving Koh Phi Phi
Known as a party island, Koh Phi Phi often surprises her divers with some great underwater marine life. Some of the best diving I’ve done in Thailand has been around Phi Phi Marine Park. One dive, my sister and I spotted a turtle, a black tip reef shark AND a leopard shark – all before midday. The coral is generally in pretty good shape, though the waves can make you feel a little queasy on the way out to the dive sites. I recommend using travel bands like these from Amazon Travel Sickness Wristbands (Black)
Getting there: Fly or take a night bus to Krabi, then approx 2 hour ferry to Koh Phi Phi. You can book joint bus and ferry tickets here. The more tickets you book the cheaper they get.
Stay: I have yet to find a great place to stay in Koh Phi Phi (after around 5 trips at least), I recommend showing up and using the little accommodation office near the pier. Give them your budget and they will find you a place.
Don’t miss: the beach fireshows – after I have been spoilt for fireshows living here, I still think they are impressive and the best in Thailand.
Diving Koh Similan / The Similan Islands
Diving the Similan Islands is usually on the bucket list for divers in Thailand. While the Similan islands are no longer covered on coral and marine life, they still have some great dive sites. Whale sharks and manta rays can be spotted around this area. Day trips here are extremely expensive (when I went we paid 6000 baht for two dives, compared with 2500 baht average in other dive spots around Thailand). Liveaboards are very popular here and you can often get great deals at the end of the season (April, May) if you can be flexible. This whole area is closed off during the rainy season (end of May to October) and even in October you are not guaranteed diving (my liveaboard was cancelled due to enormous waves one October). If you are considering a liveaboard then make sure it includes Richelieu Rock or at least Koh Bon for a chance of manta rays.
Getting there: The jump off point to the Similan Islands is in Khao Lak. You can book your night bus travel here on this website. Alternatives are to fly to Phuket and then travel on (sometimes two buses) two hours North to Khao Lak.
Stay: Beware of cheap accommodation here. I’ve stayed in various dives (pun intended) so nowhere to recommend.
Don’t miss: Khao Lak’s tiny national park with a few secret hidden beaches to discover along the way. For more on Thailand’s National Parks, read my post here
Diving Richelieu Rock
Arguably the best dive site in Thailand, I was lucky enough to spot my first whale shark here and therefore it will forever by up there in my memories of great dives. The dive site has lots of pretty purple coral and is claimed to be one of the best spots for whale sharks in Thailand. ( If only we could hold the whale sharks to that…!). North of the Similan Islands, it’s about a two hour, fairly bumpy, speed boat ride to get there.
Same details for Khao Lak, see above.
Diving Koh Phangan
Diving on Koh Phangan can be both great and disappointing in my experience. Sail Rock dive site has a lot of shoals of fish so if you’re looking for quantity then diving here can be impressive. The coral is fairly pretty, although expect a lot of divers underwater around the time of the Full Moon Party. The visibility is always worse around Full Moon and, unsurprisingly, there is no diving on the whole island for the day after the Full Moon party. For Full Moon Party Tips, read my post here as I’ve been to 5!
Getting there: There are several ways of getting to Koh Phangan. Options include flying to Koh Samui + ferry (more expensive but faster), flying to Surat thani or Nakhon Si Thammarat + minivan + ferry, and booking a train or night bus to Chumpon + ferry. You can check out great travel deals here on this island website.
Diving Koh Tao
While diving on Koh Tao has seen its reputation take a nose dive (!), it remains one of the cheapest places to get your Open Water Certificate and there are 75+ dive centres to choose from. If you just arrive on the island, use your negotiation skills to get your diving qualification and accommodation throw in together. Be prepared for it to get very busy underwater.
Getting there: there are multiple options. I recommend night bus or train to Chumpon and then ferry from Chumpon to Koh Tao, book your tickets here.
Don’t miss: a trip to Ang Thong Marine Park- I’m yet to go but have heard great things.
Ao Nang Islands, Krabi
Many dive shops in Krabi will also advertise taking you to Koh Phi Phi Marine Park, but a cheaper alternative is to stay and dive the local islands. Visibility is not always the best but when I went I saw two bamboo sharks and I was lucky enough to see this amazing seahorse. I find there can often be lots of marine life to see even when some of these dive sites don’t shout about it. Ao Nang also offers a great jump off point for island hopping around Railay, Koh Phi Phi, Koh Lanta, Koh Yao Noi and more.
Getting there: Fly or night bus to Krabi and then take the airport shuttle or songtaew (truck) to Ao Nang area. . Book your bus tickets using this handy website.
Stay: I loved the location and pool at Timber House in Ao Nang, book your stay here on Agoda
More dive posts coming soon: snorkelling around Koh Lipe was beautiful but I have yet to dive there and I’m planning on a few dives around Phuket once rainy seasons finishes. Watch this space.

Useful Dive Items
I never go diving without my Gopro Hero 4. I’m convinced the moment I do is the dive when I will see five sharks, 10 mantas, some dolphins and a whale. Buy GoPro HERO4 BLACK from Amazon here
It took me a while to figure this out but your underwater dive photos and videos will look shit unless you include a red or orange filter. (Should have listened more on that colour loss part of the Advanced Open Water!) Get yours here Polarpro Red Filter and make sure you remember it when you dive. Or your photos will look like my whale shark one above – very blue!
If you get cold easily then I recommend using a long sleeved rash vest under your shorty wetsuit. I am yet to find a dive shop in Thailand that would give me a long wetsuit (for free). I always use my billabong rash vest to keep warm on those longer, deeper dives. And especially for liveaboards when multiple dives means a lower overall body temperature. Buy a similar one here from Amazon, Dakine Women’s Persuasive Snug Fit Long Sleeve Rashguard
