Fadiouth, Senegal

Population: 9,000
Area: 0.06 sq. miles

Why you should go: Take a trip back in time with a visit to this island village, which is made of seashells accumulated over many centuries and held together by the roots of mangroves and reeds. On this isolated island, you can find a selection of interesting arts and crafts stalls.
