Once you enter the water, please be sure to move carefully and slowly, as the jellies are extremely fragile and could get harmed by fast movements. As you swim further into the lake, you will be surrounded by millions of pulsating golden globes. These are Mastigias Jellies and have evolved over millions of years into an animal that no longer needs its predatory stinging cells.
The jellies have become farmers of an algae similar to that used by coral reefs. This algae lives inside a jelly's tissues and all the algae needs to survive is sunlight where it photosynthesises the suns rays into sugars. The jelly uses an enzyme which it gets from a nitrogen rich layer of water deeper in the lake every night to capture the energy it needs from the algae. Hence, the daily cycle of following the sun in the day time and sinking deeper at night to 'fertilize' themselves.

It was once believed that the clay here had youth enhancing properties, and that if you covered yourself in this clay and let it dry before washing it off, it would be as good as a spa treatment for your skin!
Getting covered in white clay for that special Rock Island experience is all part of the adventure!
The beaches with their beautiful white sand contrasting sharply with the azure blue of the sea and the lush green of the fauna can really take your breath away, and it is this that makes the beaches here so special.
Some of the beaches here are protected as they are nesting grounds for green turtles and terns.
The Natural Arch is one of the nicest photo opportunities seen on the Rock Island Tour.
This formation of limestone which has been eroded over the years is a pretty impressive sight, and great for that souvenir photo of the Rock Islands.
If you are really lucky, your boat driver may stop for a short while to enable you to swim up to the rock and have your photo taken on it, or at high tide the most experienced of boat drivers will drive right through the arch, providing a thrill for all on the boat.
On the other side of this island is Fantasy Reef. This is a beautiful snorkel spot, abundant in a huge variety of reef fish, of all shapes, sizes and colours; as well as stunning coral formations.
Even if you don't have an expensive underwater camera, the clarity of the water and the shallow depths mean that your basic point and shoot cameras are more than suitable for you to be able to photograph the beauty of the underwater world!
