The Best Dive Sites in Koh Tao and Why You’ll Fall in Love With Them
Koh Tao may be famous for turning backpackers into scuba addicts but its real magic happens underwater. Sure the beaches are cute and the sunsets look like someone turned the saturation to maximum but the dive sites are the real show stealers. If you already have your certification and want to see the island at its absolute best these three sites are the holy trinity.
And yes we run trips to all of them on a comfy catamaran that is basically the opposite of the usual big, loud, bulky boats you see around here. More on that in a bit.
Quick answer: The three best dive sites in Koh Tao are Chumphon Pinnacle, Southwest Pinnacle and Sail Rock. Chumphon Pinnacle is a deep granite pinnacle known for trevally, groupers, barracuda and whale shark sightings; Southwest Pinnacle is a colourful cluster of pinnacles with soft corals, batfish and turtles; and Sail Rock, the standout of the Gulf of Thailand, features a famous vertical chimney swim through and huge schooling fish. All three are for certified divers and can be combined on a Best of Koh Tao and Sail Rock catamaran trip.
Chumphon Pinnacle
If dive sites had fan clubs this one would have a waiting list. Chumphon is a massive submerged granite pinnacle covered in anemones and the occasional pair of bannerfish that look like they’re gossiping about you.
Here you can spot huge schools of trevally giant groupers, the occasional visiting whale shark and enough barracudas to make you rethink your place on the food chain. The vibe is big blue open water and lots of action. It’s a bucket list dive for good reason.
Our Best of Tao trips visit Chumphon regularly and yes it’s on the fancy catamaran with the large dive deck, a sunbathing area and even a nitrox compressor. Certified divers only, because this site does not play around.
Southwest Pinnacle
If Chumphon is the dramatic deep ocean celebrity Southwest is its cool free spirited cousin. This site is made up of a cluster of pinnacles covered in soft corals, sea fans and the kind of marine life that makes photographers start screaming excitedly into their regulators.
Expect big schools of fusiliers, batfish that think they should be on camera and sometimes turtles cruising by like they own the place. Southwest is colorful, full of life and always a crowd pleaser.
Our Best of Tao trip includes this beauty too and trust me it feels even better when you arrive on a smooth stable catamaran instead of fighting for elbow space on a noisy dive barge.
Sail Rock
Now for the superstar. Sail Rock is one of the best dive sites in the entire Gulf of Thailand and she knows it. The famous vertical chimney swim through is the highlight but the whole site is buzzing with life.
You’ll find big schools of fish circling like underwater tornadoes plus queenfish trevally and sometimes the big friendly spotty one everyone secretly hopes for. The visibility often surprises you in a very good way.
Our Sail Rock dive trips give certified divers the chance to dive this gem with three full dives plus breakfast tea espresso coffee soft drinks lunch and all your gear included. The espresso is real espresso because you deserve dignity at sea.
Why go with us
Alright I was trying to be subtle (not so much), but here’s the truth: The catamaran experience changes everything.
