Where we dive
We rotate sites based on weather and visibility. Some of our regular sites:
Chumphon Pinnacle
Big-fish site. Whale shark sightings in season, schools of barracuda, batfish year-round.
Sail Rock
Best dive in the Gulf. 6m chimney swim-through, big schools, sometimes whale sharks. Full-day trip.
Twins
Two pinnacles, sandy bottom, easy 12-18m. Great for buoyancy work and macro spotting.
Shark Island
Wall dive on the south side. Reef sharks, turtles, anemones - usually our second dive.
Hin Wong Pinnacle
Quieter site, great viz on flat days. Best for photographers.
Southwest Pinnacle
A cluster of pinnacles dropping to 28m. Big schools, groupers, whale sharks in season - quieter than Chumphon.
White Rock
Koh Tao's biggest reef and a local favourite. Easy terrain, tons of fish, great for a relaxed dive or a night dive.
Mango Bay
Shallow, calm bay on the north coast. Healthy hard coral and macro life - perfect for easy, long, low-current dives.

"Our instructors Chris and Noah were incredible — kind, helpful, funny and patient. We owe a huge thanks to Siam Scuba, easily one of the nicest dive shops in Koh Tao."
