Koh Haa
“The macro paradise”
Well known for its environmental water quality.
Koh Haa, amazing site for all!
This beautiful archipelago is located two hours away from every inhabited island. Actually, Koh Haa site consists of five separate islands (although a pinnacle joined to Koh Haa 5 has earned the rather confusing nickname of “Koh Haa 6” and represents a dive site of its own).
There at Koh Haa site, you will find reefs, lagoons, swim troughs, huge caverns, and a wide variety of marine life, including the occasional pelagics, such as manta rays and whale sharks.
Several stunning sites
Most popular for “the chimney”, this vertical swim-through begins at a depth of around 4 meters on the western corner of the island and descends to a small cavern at approximately 9-10 meters, from where divers continue diagonally down to exit at approximately 17-18 meters.
Fascinating site
This is a favorite spot to visit both for divers and freedivers. If this seems scary a bit, then as an alternative, spherical cavern nicknamed “the fish bowl” after the school of bronze sweepers that are found residing there can be accessed behind the chimney at approximately 8 meters. The site itself consists of walls, plateaus and sloping reefs and is an excellent place to spot nudibranchs, shrimps, pipefish and the occasional frogfish along with much more wonderful marine life.
These islands come together to form a magnificent lagoon which has a lot to offer both for beginners and more experienced divers. Nice sandy areas provide an excellent place for students to practice skills easily and without fear of damaging marine life. Experienced divers will be certainly amazed by the plethora of that very same life, including frogfish, mantis shrimps, octopuses, harlequin shrimps, pipefish, sea moths and turtles, and occasionally even whale sharks!
Incredible layers
The outer side of the Island 4 is a steep wall dropping from the surface down to around 22 meters, from where a sloping reef then continues down to around 35 meters. There is a sloping sandbank between Island 4 and Island 2 that makes an opportunity for a short “muck” dive on the spot where many interesting marine creatures have made their homes in the sand. The wall rises again from the depths at around approximately 20 meters to make up Island 2, but unlike her sister, the majority of this dive site is made up of sloping reefs.
Amazing lagoon
For those who have not yet made the plunge beneath the water with diving, snorkeling in the shallow lagoon within the borders of these three islands is a must-to. There are substantial areas of hard corals just meters below the surface and a small beach on Koh Haa 3 can also be accessed for those who may wish to rest during their snorkeling activity.
Koh Haa Yai is the largest island in the archipelago and is most famous for the Cathedral, a series of three large caverns located to the south of the island. Two of these caverns begin at approximately 14 meters deep and rise up to the surface, while the last one continues to rise for approximately 10 meters more. In favorable conditions, divers can surface in this largest cavern that offers an amazing unique diving experience. It goes without saying that this is reserved for technically skilled cave divers only.
Great for all
The site itself consists of small walls and sloping reefs descending down to approximately 25 meters. On the other hand, sandy beach area is an excellent place for students undertaking diving courses and a great place for snorkelers seeking for shallow areas to enjoy in wonderful marine life of the island. This spot is also notable for finding various forms of macro life, including nudibranchs, frogfish, and shrimps. Turtles and octopuses can also be regularly seen by keen diver’s eye.
The rather confusingly named Island 6 is actually a small pinnacle at the north end of Koh Haa Yai. It is connected to the island by a short sandy ridge approximately 13 meters deep. Not visited so often like the other islands of the archipelago (maybe due to lack of sand areas for students to use), this beautiful site should not be in no way dismissed! Offering unlimited wealth of soft and hard corals it attracts a wide variety of marine life, both small, within the pinnacle confines, and large in the surrounding blue. Occasionally, it even gets visited by leopard and whale sharks.
WHAT PEOPLE SAYS
Big Thanks to Blue Planet for a great day 3/3. And specially thanks to Brice who was a very professional and nice diveinstructor. He gave me a very good refresh for my OW cert because its been a while sins my last dive. After that we did two really good dives at Koh Bida.

4 March 2020Together with my son and daughter we booked a day dive trip to Koh Haa, Hin Muang and Hin Daeng, with Blue Planet Divers. Although a bit expensive (specially after Koh Tao), we were very satisfied with the high quality of their service. The office staff were kind, friendly and helpful with information in both english and french. Highlights: catamaran trip to dive sites with tasty food and enough space to chill and admire the beautiful landscape * well maintained equipement * Koh Haa is a must! With caves, extraordinary biodiversity and a gorgeous setting. Thanks to Yann, Johan and Fins for their diving support. Highly recommended!

I just did my open water diving licence there and the guys from the Diving Center are doing a very professional job (they are not overwhelmingly friendly or funny, I... read more felt like they keep a professionelle distance)
, everything went on really fluent, the boat trip to the spots was enjoyable (thanks to the anti sea-sickness pills from the Diving Center), the food was delicious, the thai staff was extremely friendly, and the dives have been nice! I did the course because I am/was really afraid of deep water, the sea, swimming... I always felt like water is just not my element. With all the knowledge I got and my very calm and sophisticated teacher (thanks Raf) I managed to go down and keep breathing. From Dive to dive my fear shrunk and I could enjoy my experience. The only thing what I was missing was a long wetsuit as I started freezing at the end of every dive.Stay08598734055
9 February 2023Blue Planet was very responsive on WhatsApp to organise the dives, and the package quoted for 2 days diving was very reasonable. They pick up and drop off from your... read more hotel. The catamaran is large, clean and well appointed. Lots of room to chill between dives. Breakfast, lunch and snacks provided on board were really good quality. The quality of the diving gear is fine. There were two of us and we did 3 dives each for 2 days. Groups are small, with no more than 4 individuals per guide. Our guides, Brice and Mark were both excellent, both knowledgeable and attentive and really made our trip special. All the staff and the owner are very pleasant and helpful.
Overall, am very impressed with Blue Planet Divers, would thoroughly recommend. Thank you to Blue Planet!pap5225
1 January 2023Fantastic day diving and snorkelling with Blue Planet Divers. Our sons (11 and 14) tried a Discover Diving day and my wife and I snorkelled. Etienne looked after the boys... read more and was the perfect blend of friendly and professional. We felt safe and well looked after from the minute we were picked up at our hotel and throughout the whole day. We were lucky enough to see loads of fish and reef tip sharks. Matt took some fantastic photos that you are under no obligation to buy but you will definitely want to as they are far better than anything you can take yourself. Would definitely recommend to others and already have.

25 December 2022This shop is amazing, they are very professional, super friendly and organized, the boat is quite nice and the food on the boat is delicious.
We did 4 dives... read more and an open water course, plus we stayed at their hotel (the dive house) which was extremely comfortable and convenient, you get out of the boat and you're 10 meters away from your room.
Laurens was a great instructor and guide, we saw a lot of beautiful ocean life and had a pretty epic experience. The staff on the boat is also quite professional and friendly, they run a tight operation and make you feel safe.
There is also a professional photographer, Matt, who does amazing work.
Highly recommended!902fernandoo
