West of Six - Similan Islands

West of Six, or West of Eden as some call it, really shines in the shallows. We often start the dive in a sheltered bay, a good spot to look for turtles cruising by or a school of batfish hanging out. Drop down and you’re immediately into some of the Similans' healthiest hard coral, with those big acropora tables and colourful gorgonian sea fans everywhere. It's a gentle drift over granite boulders, covered in dense coral growth, making it a favourite for liveaboards looking for an easy, colourful dive. It’s a great site for photographers or anyone who just wants to soak up the vibrant reef in relatively calm conditions.
