Surprisingly, Twins should actually be called "Triplets" because it consists of three pinnacles. There are two large collections of boulders covered in corals and a smaller, deeper group of rocks a bit farther west!

Twins is hands down one of the most popular dive sites on Koh Tao, ideal for both recreational divers and those looking for the perfect PADI training site! Another reason why this dive site is such a hit is its strategic location, ensuring scuba divers can enjoy their dives even in monsoon weather. It's a top-notch spot for diving, and the marine life here is thriving.

The shallower pinnacle boasts Christmas tree worms, adding their colorful touch. You'll see Longface Emperor fish, Pipefish, and Yellow Boxfish tucked into the rocky crevices. Look under the ledges, and you'll spot the Blue Spotted rays, while in the shadows, curious Snappers make their appearance.

Now, the middle pinnacle is where the action's at, including an archway ! It's like a bustling neighborhood here with various reef fish and a bunch of different Wrasse, Groupers, Parrotfish, Bannerfish, Trevally swimming in small groups, Pufferfish and porcupine fishes !


And just north, there's Buoyancy World, artificial structures that attract all sorts of fish and coral growth, along with buoyancy structures that help new divers hone their skills.

Keep venturing , and you'll hit the final pinnacle. This spot is a haven for all you macro lovers out there! Seahorses, Cowfish, Nudibranch, Wart Slugs, Janns Pipefish, Mantis, Durban Dancing. And don't miss the tiny Indian Walkmans hiding in the sand. Keep those eyes peeled for these masters of camouflage!

And if you're lucky, you might just catch a glimpse of a majestic Hawksbill or Green turtle gliding by. But be on the lookout for the Titan Triggerfish—they can get a tad territorial, so it's best to give them their space
