About Us

Welcome to Ko Hai Divers (aka Rainbow Divers), the first dive school on Ko Hai (Koh Ngai), established in 1995. We offer a relaxed, friendly and safe atmosphere and look forward to showing you some little known dive spots in Thailand. With us you can do all PADI recreational courses from Discover Scuba Diver to Divemaster. All in small groups.

Our Dive shop is open every year from beginning of November to end of April. This period offers the best weather and diving conditions off the west coast of Thailand. Besides half day tours around unspoilt and beautiful Koh Ngai and Koh Waen we also offer full day trips to the famous dive sites around Koh Rok and Koh Haa.

​

We speak English, German, Spanish, Greek, Thai, Dutch and some Italian and French.
