Dive Sites
H2O Original offers trips to the most popular diving sites in the Gulf of Thailand. Because of our unique speed boat service, we are able to offer trips to other lesser known, but no less spectacular dive sites like:


Sail Rock

Good for all levels

Widely known as the best site in the Gulf, this local treasure is famous for whaleshark sightings! Whether you see these gentle giants or not, you will be amazed at the amount of marine life found here daily. Barracuda, large schools of silver travelly , giant moray eels, colourful corals... the list goes on! The unique pinnacle rises out of the sea, and most of the marine life is found quite shallow. This means long exciting dives for everyone, no matter how experienced you are. A trip to Sail Rock with H2O is like no other; departing at 12:30pm straight from Thong Nai Pan Beach, we journey approximately 25 minutes to arrive at the site just as all the busy boats from the morning are packing up to leave, giving us exclusive access. Most days we are the only boat onsite, allowing our divers to experience Sail Rock to the fullest. For this trip, we take a maximum of 10 divers per day, so it will never feel crowded!


Koh Tao

Good for all levels

Famous for the amount of sites in close proximity to this little island, Koh Tao offers colourful sites like Shark Island, Ao Leuk, Tanote Bay, Mango Bay, White Rock and more. Here we have shallow reef sites, ranging from 8 meters to 18+, which host a wide variety of beautiful creatures including blue spotted stingrays, blacktip reef sharks, turtles, puffer fish, butterfly fish, unicorn fish, bat fish, banner fish, angel fish, grouper, and colourful hard and soft corals. A favourite for beginners, this site is only 50 minutes away and H2O take you there in the mid-day window when all the busy Koh Tao boats are back
on land for lunch. Remember, we take you to see fish, not people ;-) We take snorkelers along when we visit Koh Tao as the conditions are shallow, sheltered, and appropriate for snorkelers of all ages and levels.


Ang Thong

This site, although only in season for a short time of year, is spectacular. If you are lucky enough to be here when it is in peak season, you’ll see a stunning diversity of marine life within this national park. An hours journey by speedboat, we visit the two northernmost islands where you’ll find pristine coral reefs, exciting island swim-throughs, lion fish, cuttlefish, turtles, blacktip reef sharks, banded sea snakes, blue spotted stingrays, clouds of fusilier, all the colourful reef fish found in the Gulf, and at a shallow depth, accessible to beginners and experienced alike.
