Post Office Bay on Floreana Island in the Galápagos Islands, Ecuador, is a historic coastal site known for its long-standing postal tradition. Visitors can leave or collect letters from a wooden barrel, follow walking routes, snorkel along nearby shores, and see Darwin finches, lava lizards, and yellow warblers. Established in 1793 by sailors, the informal postal system continues to function today, with travellers hand-delivering mail when possible.
