Motor sailed over to Ilot Mato which is one of the higher islands in the southern lagoon area. It is surrounded by an extensive reef and tiny sand fringed islands. It is also home to lots of the local banded sea snakes which are quite unconcerned about visitors to their home. At times there is a red flag to indicate whether or not you can go to the island due to it being a nesting site for birds. There was no flag for us so we climbed the single hill for a fantastic view over the surrounding reef and lagoon. We saw turtles and a couple of black tipped reef sharks hung around the back of the boat for quite a long time.
