Golden temples, floating markets, and street food that awakens the senses… yet beneath the surface, an even more astonishing spectacle awaits. In Thailand, spirituality, nature, and adventure go hand in hand.
While monks walk barefoot through the streets at dawn, you could be getting your gear ready to dive with manta rays, sea snakes, or seahorses camouflaged among the corals.
Diving in Thailand is like entering a parallel universe where calm transforms into pure excitement beneath the sea. Whether you’re new to diving or already have hundreds of dives under your belt, here you’ll find unique experiences, underwater landscapes that look otherworldly, and breathtaking encounters with marine life.

The Best Places to Dive in Thailand:
Similan Islands
The ultimate paradise for divers. Its turquoise waters and pristine beaches hide stunning underwater scenery: huge granite boulders, colorful corals, and a diverse marine life.
From turtles and blacktip reef sharks to manta rays and whale sharks during the right season.
Richelieu Rock
A world icon for diving and the site that surprised us the most, thanks to its explosion of color and life. With a horseshoe-shaped formation covered in purple soft corals.
It’s a festival of life: seahorses, ghost pipefish, harlequin shrimp, and with a bit of luck, the majestic appearance of a manta ray or a whale shark. A spot you’ll want to dive again and again.

Koh Bon
The hotspot for seeing manta rays. With vertical walls and coral gardens where napoleon wrasse, giant moray eels, and multicolored nudibranchs lurk. The currents here challenge even experienced divers.
Koh Tachai
Famous for its Twin Peaks, a vibrant site with turtles, barracudas, and real chances of seeing manta rays and whale sharks between January and April. Strong currents and depth make this a place for the most adventurous divers.
Surin Islands
More remote and wild. Their reefs are full of hard corals, turtles, napoleon wrasse, and humphead parrotfish. Diving here feels more authentic and peaceful, far from the crowds.
Khao Lak Wrecks
A sunken ship at 20 m deep, turned into an artificial reef teeming with life: huge moray eels, schools of jacks, and lionfish. Even whale sharks can sometimes be spotted. A different kind of dive, full of history and mystery.
Why You Should Dive in Thailand
Thailand is pure adventure both on land and underwater. Two different seas offer you a variety of landscapes: pinnacles covered in corals, caverns, endless reefs, and wrecks bursting with life. You’ll see everything from massive pelagics like mantas and whale sharks to the tiniest, most colorful nudibranchs. And all this comes with warm waters and exceptional visibility nearly all year round.
