Nice Island , we used to stay at a resort there a long time ago, there is a tropical rain forest which is nice to see, also island as some neat black sand beaches, there are thousands of monkeys that also live on the island and you can see just moving around.
We did an island tour by bus one time. Most recently we did the train ride -- very nice. There are 2 levels to the train. We chose to sit on top for the better view. The lower level of the train is air conditioned.
