One day we hired a driver to take us around the island.
One of the places we stopped was the Blue Lagoon which is a small semi freshwater lagoon with large lime stone deposits making the water very blue to look at.

We also stopped at Turtle Bay which is supposed to be a turtle sanctuary...but for what it is (tiny) and the knowledge of your guide (none) very over prised.
But they did have some live coconut crabs.

Some baby turtles

And a couple of large turtles in a very small and dirty enclosure.
