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 Ko Hai Fantasy Resort, just steps away from the beach. 

We use 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 and Coltri 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 Ko Hai to dive the famous dives of Hin Daeng, Hin Muang, Ko Haa islands and Ko Rok and then travel south to Ko Lipe (Tarutao National Park) to dive the famous 8 Mile Rock, Stonehenge, the Yong Hua wreck, Ko Sarang and many more.

There is a direct speedboat connection from November to April between the two islands of Ko Hai and Ko Lipe in less than 3 hours.



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 our instructors Leire and Michel.
