Ko Hai Divers

Rainbow Divers was established in 1995 on Ko Hai and has a long history and reputation of being the only and then the best dive centre of the Trang islands. Since 2017 we operate as Ko Hai Divers. You can find us behind the restaurant of the Koh Hai Fantasy Resort, just steps away from the beach. 

We use mainly Scubapro equipment (MK2 regulators, T1 BCDs) and 12 l aluminium tanks with INT valves. We have DIN adapters available for you. We fill the tanks ourselves using our professionally serviced Bauer compressors. We provide 3mm Shorties, which keep you warm in 28 to 30 degree water. 

Ko Hai Divers is managed by Beltran and Britta while Antoine has the management of Forra Dive Resort on Ko Lipe since 2002. The two operations are directly linked, so that it is very easy for divers staying on Koh Ngai to dive the famous dives of Hin Daeng, Hin Muang, Koh Haa islands and Koh Rok and then travel south to Koh Lipe (Tarutao National Park) to dive the famous 8 Mile Rock, Stonehenge, the Yong Hua wreck, Koh Sarang and many more.

There is a direct speedboat connection from November to April between the two islands. It takes about 3 hours to reach Koh Lipe from Koh Ngai.



Ko Hai Divers is a small shop offering a friendly and relaxed atmosphere. It is managed by Beltran and Britta, our instructors. They are in charge of the daily organisation, logistics, customer service, but also love to take you on fun dives or teach you how to dive. 

They are supported by two additional Padi instructors.


Beltran is co-owner of Ko Hai Divers. He is Open Water Scuba Instructor since 2009 and has plenty of experience diving in Thailand and all over the world. He can teach PADI, SSI and NAUI and is passionate about underwater photography.

Beltran is originally from Madrid and speaks Spanish and English fluently. He also knows his way around in Italian and speaks a bit of French.
