Hi Calum, and thank you for the great review of our excellent staff and diving with us. We are very lucky to have some of the best diving in Thailand here in the Andaman Sea. It's not often that students on the PADI Open Water Diver course get to see a whale shark during their first few dives - but we've been very lucky to have several whale sharks hanging around Koh Haa recently. We hope to see you back on Koh Lanta for some more diving int eh future, and lets hope the whale sharks hang around for a little longer :)
