Head to Koh Talu for a snorkelling tour. Talu Island is a gem, set in the middle of the turquoise seas and only 15 minutes by boat from the nearest fishing town. It is called an aquatic wonderland thanks to the abundance of snorkelling locations where you will easily be able to find delicate and new coral species the likes of Staghorn Corals, Mushroom Corals, Branching Pore Corals among others. The water is clear enough that you can see the bottom of your boat. Make sure that you are well protected against the sun with a strong SPF cream.
