Also known as South Seymour, Baltra’s flat landscapes contrast with the rest of the Galápagos’ steep volcanic terrain. This seismically-formed isle was chosen by the US government as an air base in the 1930s, thanks to its central location and flat ground. The base was used during the Second World War before being given to the Ecuadorian government. Today, it’s one of just two entry points to the archipelago by plane.
