Scuba Refresher

Together we’ll spend about an hour going through the theory reminding you about air spaces in your body and equipment and the dive procedures. Then in the afternoon we can set up the equipment together, we'll buddy check each other and then do a giant stride into the sea. Once you have yourself all comfortable  & relaxed we'll then have a go at doing some of the shallow water skills with the regulator & the mask, before having some fun with a few buoyancy skills in slightly deeper water.

There will be time thereafter to go for about a 20-minute dive, working on your air conservation, buoyancy skills and then check out the local marine life.

While on the boat you have the option to do another fun dive to make the most of the skills you have just refreshed, you'll find yourself far more relaxed and conservative with your air supply, this is an additional 1000 THB if you choose.

Price for the Scuba Review is 2000 THB including all equipment & manuals. Click here to book your Scuba Refresher

Fun Diving

Big Blue has been diving these waters for years, our experienced dive masters are well versed in the dive sites, conditions and the marine life of Thailand.

They will guide you to the best diving in the area and will be delighted to show you the beautiful wonders of our surrounding waters. A number of sheltered sandy bays provide the perfect depths for novice divers, while the more adventurously inclined can visit deeper sites and perhaps even live the diver's dream of spotting a whale shark or two.

Generally the boats go out 2 to 3 times a day. The morning trips leave Koh Tao in-between 06.45 and 07:00 and gets back around 11.00. The afternoon trips leave in-between 12.30 and 13:00 and gets back around 17.30. We do 2 dives at 2 different dive sites on both trips.

Currents are usually minimal and the water temperature ranges between 26 and 30C; perfect for tropical diving.

Our prices start at 1000THB for 1 or 2 dives, 900 THB for 3-6 dives, 800 THB for 7 dives or more. Click here to book your fundives

Full Day Trips

We offer up to three Full Day Trips every week to one of the Gulf Of Thailands most exciting Dive sites- Sail Rock. A Full Day Trip leaves at 6.30am when a Full English Breakfast Buffet will be served as we head out to our destination. Nice loooong surface intervals to enjoy the sunshine the scenery & the entertainment is the norm on a Full Day Trip. After our second Dive a Thai buffet lunch is served & after our third & final dive of the day the trip home is accompanied by Chocolate Cake for everyone! The highlight of the day. Back to Koh Tao by about 5pm. This is always a very popular trip and can fill up quite quickly. These trips can also be dependent on the conditions.

 

We are very excited to announce that very soon we will be offering Day trips to Ang Tong Marine Park and also Chumphon Marine Park. These are not available just yet but watch this space for more information.

Nang Yuan Pinnacle and Cave

nanyuanpinKoh Nang Yuan lies northeast off the coast of Koh Tao. Nang Yuan Pinnacle, is a small granite pinnacle that rises out of the water from depths of about 20-24m. This dive site is suitable for all levels though during full moon, currents may be experienced. Whip coral, soft coral and sea fans are common and blue spotted stingrays are abundant and a huge number of groupers can be seen hiding in nooks and crevices. Turtles are sometimes seen foraging among the coral or resting on top of the pinnacle.

Twins

TwinsDo you remember when your instructor told you to look for the small things? Twins is the ideal place to take that advice. Two groups of rocks at depths from 10m to 18m. Your divemaster or instructor may show you the haunts of grouper, panda clownfish and stingrays, but if you take your time and look closely you might also see anemone shrimp, morays, flatworms and pipefish, as well as cleaner wrasse at their never-ending work.

Check the crevices for baby angelfish, keep an eye on the water above for squid and crocodile longtom and look for the dancing fins of the juvenile sweet lips.

Hin Wong Pinnacle

HinwongOn the east side of Koh Tao lies Hin Wong, a large and very varied site ranging from depths of 10m to 32m. Although visibility here is unpredictable, Hin Wong is covered in lacy sea fans and curly wire coral, as well as filefish, snapper, coral grouper and other reef fish. The resident turtle is only shy if you get too close. Observe her from a distance and she'll eat placidly away.
For the macro-minded, Hin Wong also has some beautiful invertebrates. Look especially for brightly colored nudibranchs.

White Rock

WhiterockSay hello to Trevor! White Rock, consisting of two groups of rock separated by a narrow channel of sand (depths from 9m to 24m), is home to Koh Tao's single most notorious fish: Trevor the Trigger. A Titan triggerfish that has been the boss of the site for years, Trevor occasionally takes exception to divers disturbing his rest. But no need to spend the dive looking over your shoulder, let Big Blue's instructors and divemasters keep an eye out while you enjoy the sea snake, turtle, moray, blue spotted ray, butterfly fish or angelfish.

Look closely in the stag horn coral for porcupine fish and hermit crabs, and see if you can spot a well-camouflaged scorpion fish or two.

Green Rock

GreenrockFascinating rock formations create small caves and swim throughs at Green Rock, which ranges in depth from 4m to 28m. Brightly colored nudibranchs are omnipresent, as are morays, harlequin sweet lips and blue ringed angelfish. White tip reef sharks can be seen from time to time, and at the deeper end of the site large grouper and schools of yellowtail, fusilier and silverfish can be seen. Look out for "the minefield", where scores of yellow margin and Titan triggerfish have made their nests in sandy pits.

Shark Island

Shark IslandPossibly Koh Tao's most varied site, Shark Island is a small uninhabited island just to the southeast of Koh Tao. Sloping gently from the surface down to 24m, there is always something new to see here including some of the Gulf of Thailand's most stunning soft coral.
White eyed moray eels, blue spotted fantail rays, porcupine and puffer fish, and an enormous variety of reef fish are almost guaranteed in the beautiful shallow coral garden, while the fortunate may also see whale sharks, leopard sharks, reef sharks and other pelagics on the deeper side.

Titan triggerfish add an element of excitement to each dive, and divers often spot turtles and sea snakes.

Sail Rock

SailrockA single rock that protrudes from the water between Koh Tao and Koh Phangan, Big Blue in Koh Tao visits Sail Rock less often than the other sites, but the dive is well worth the trip. The most noticeable feature of the dive is "the chimney" - a vertical tunnel in the rock that leads you from 18m to 8m, but the entire site (from the surface to 45m) is full of points of interest. The rock is riddled with small holes which makes a perfect habitat for white eyed and yellow margin moray eels, and the large anemones that cover it are filled with anemone fish and shrimp.

Whale sharks can be seen in the winter months here as well, and keep an eye out for other large pelagics. Octopus camouflage themselves so exactly to match the covering of the rock that you may miss them completely, but keep your eyes peeled - they are there.
