There were three of us in February (2 AWD, 1 instructor) and we did several diving days with ME Diving... Richelieu Rock was absolutely madness - millions of fish, breathtakingly beautiful!
I was looking for a dive center that would arrange for me to dive in Thailand... It was an unforgettable dive in the Similan Islands. The organization is beautiful, every detail is provided.
Our last day of diving was booked for a long boat... guide Freddie was knowledgable and friendly and couldn't have been any more helpful.
Having just completed our PADI Open Water, we booked trips to The Similan Islands and Richelieu Rock... Edan guided us superbly, keeping us safe on all dives.
