7 of the Smallest Islands in the World—Including One Made of Shells

"Often noted as the world’s smallest island with a building, this sliver of rock is roughly 150 feet long and about 50 feet wide, most of it occupied by a massive lighthouse. You can visit the lighthouse and the surrounding Isles of Scilly waters on a boat tour, with chances to spot seabirds, dolphins, and seals." - Stacey Leasca Stacey Leasca Stacey Leasca is an award-winning journalist and co-founder of Be a Travel Writer, an online course for the next generation of travel journalists.
