The uninhabited island of Monuriki, part of Fiji’s Mamanuca Island chain, has an area of less than one square mile (1.6km). If you’re hoping to spend the night there, you’re out of luck. But there are a variety of daytime activities to take part in. If you’re looking to catch some rays, snorkel or swim, you can check out one of its pristine, white-sand beaches complete with crystal-clear waters. While you’re there, go on a guided nature walk that features mesmerizing volcanic rocks.
Fadiouth, Senegal
Fadiouth Island is one of the most remarkable geographical anomalies in West Africa, composed of billions of seashells. The man-made island can be accessed from mainland Senegal by a wooden footbridge, making it easy and convenient for locals and travelers alike to go back and forth. As you explore, your feet crunch with every step. The streets, the alleys, the foundations of the houses, and even the local crafts are constructed from or embedded with white clam shells. No trip would be complete without visiting the over-800-year-old baobab tree, which is located at the highest point of the island’s cemetery.
