Esperanza International Airport is Antarctica's second largest airport and 51st largest airport in the world. It is located in Esperanza, Havlo, the second largest city in Antarctica. Many people fly here for many attractions such as the Wild Antarctic Observatory, where many penguins are observed, and a very large tourist area with an underwater tunnel. There's also Great Glacier Antarctica climbed by many mountaineers year by year. However it is not the largest in Antarctica. McMurdo Airport (MCM) is the largest airport in Antarctica. Esperanza Int'l Airport (ESP) opened in 2027, before McMurdo. However before long, McMurdo would become the largest city in Antarctica.
