Why you should go: There are caves and then there are the Crystal and Fantasy Caves of Bermuda, singular grottoes filled with stalagmites that look like cake icing dripping over an azure subterranean lake. Located in Hamilton Parish, these stunning chambers were discovered in 1907 when two boys playing cricket stumbled upon them. Hollywood took notice and in 1913, Neptune’s Daughter was filmed on-site. Later, the legendary puppeteer Jim Henson would produce Fraggle Rock, a children’s television show inspired by the island catacombs.
