I booked this tour for my husband and I prior to leaving and am so glad that I did. It is another attraction not to be missed BUT you need to ensure that the tour company that you use gets you there while the tide is out or you will miss the private beach that you can only get to at that time.
Now, the Islands are a sanctuary and can not be walked on, except for the beach I mentioned before. The Islands have 78 species of birds and are made from volcanic rock. It's also a great location to snorkel and see the fish that surround them.
It's hard to explain the beauty as you can only really see it in person.
