The southern part, right by the beach, serves as a training ground for new divers. It boasts shallow depths, ranging from 3 to 15 meters, providing the ideal environment for those taking their initial underwater steps, making it perfect for the Discover Scuba Diving program.

The primary caves here kick off at around 20 meters deep, offering an exciting underwater playground with different ups and downs to explore.

And while you're exploring, make sure not to miss the 'Boom Boom Room' swim-through. Inside this cavern, you'll feel the water surge with wave energy, creating a sensation akin to big bass drops that's guaranteed to get your excitement soaring! And if you're up for some deep dive training, you can even dive down to +35 meters in the sandy bottom.

Within the shallow waters and amidst the granite boulders, a diverse array of hard corals thrives, providing shelter not only to the abundant reef fish commonly found around Koh Tao but also to marine life relatively unique to this area.

Here, you can encounter the Orange-Spine Unicornfish and the Bumphead Parrotfish. This spot is a bustling underwater world, hosting an array of marine life. You can encounter a variety of Groupers, schools of Jacks, blue Spotted Stingrays, curious moray eels, Harlequin Sweetlips, Batfish, Cobia, sneaky Banded Sea Krait, Scribbled fish and the very infamous Titan Triggerfish.

Every now and then, you might even catch a glimpse of a passing Black Tip Reef Shark. Keep your eyes peeled for the local Green Turtle gliding by. And for those who love the tiny critters, Laem Thian is a paradise with its high density of macro life!
