Corumbá International Airport — Corumbá, Brazil

Wetland tourism keeps CMG relevant far beyond what Corumbá's modest population might suggest, since the city functions as one of the principal gateways into the Pantanal, the world's largest tropical wetland and a magnet for wildlife watchers hoping to spot jaguars, caimans, and enormous flocks of birds. Corumbá itself sits directly on the Bolivian border along the Paraguay River, giving the airport a secondary role in cross-border trade and travel alongside its ecotourism traffic. Flights typically connect to Campo Grande and other regional hubs rather than offering direct international service, and lodges throughout the southern Pantanal arrange ground or river transfers for visitors landing here. The airport's single runway and compact terminal reflect a facility built for a steady trickle of nature tourism rather than mass-market arrivals.
