Visited the Island of Fakarava on Jan. 11th 2013. It is a two day trip by cruise ship from Pitcairn Island. The island is a large atoll  – very narrow – about ½ mile, 28 miles long and forms a semi box shape with a lagoon in the middle.   We walked to a beach on the lagoon side of the island that had lots of coral and went snorkeling. After snorkeling we walked across to the ocean side and watched the waves. There are about 400 residents on the island and it even has and airport which you can see in one of the photos below.
