Aside from the beach, the main attraction in Placencia [1] is the world-renowned main-street sidewalk, cited in the Guinness Book of World Records as “the world’s most narrow street.” It’s 24 inches wide in spots and runs north–south through the sand for over a mile. Homes, hotels, Guatemalan goods shops, craftmakers, and tour guide offices line both sides.
