Vilo Acuña International Airport — Cayo Largo del Sur, Cuba

Vilo Acuña International Airport, marked CYO, serves Cayo Largo del Sur, an island off Cuba's southern coast developed specifically around upscale, secluded beach tourism rather than any local residential population of note. Named for a Cuban revolutionary who died fighting alongside Che Guevara in Bolivia, the airport receives charter flights carrying vacationers, mostly from Canada and Europe, drawn to the island's clear water, powdery sand, and nesting sea turtle populations. Because Cayo Largo functions essentially as a resort enclave, CYO's operations revolve almost entirely around tourist arrivals and departures rather than any broader commercial or cargo activity typical of mainland Cuban airports.
