Teniente Luis Candelaria International Airport, serving San Carlos de Bariloche in the Río Negro province of Argentina, is one of Patagonia's busiest airports. Named after Argentine aviator Lieutenant Luis Candelaria, the airport handles significant seasonal traffic driven by tourism to the nearby Nahuel Huapi National Park and the Cerro Catedral ski resort. The airport receives both domestic flights from Buenos Aires and other Argentine cities, as well as limited international services. It plays a critical role in connecting the popular resort city of Bariloche to the rest of Argentina and neighboring countries, particularly during the summer and winter tourist seasons. The facility has undergone modernization efforts in recent years to accommodate growing passenger numbers, which regularly exceed one million travelers annually. Its location approximately 15 kilometers east of the city center makes it conveniently accessible to the main tourist areas.
