Tapuaetai or One Foot Island is one of the most popular desert islands to visit out of the 22 islands in the Aitutaki atoll of the Cook Islands. As you can see from this photography, the island is breathtakingly beautiful. I went to the Cook Islands in search of the classic picture postcard of a palm tree fringed with a tropical island and surrounded by turquoise waters. I found it on One Foot Island. It was also pretty cool that they had one of the world's most remote post offices on the island where you can not only purchased and send postcards but also get your passport stamped.
