Gobernador Castello Airport — Viedma / Carmen de Patagones, Argentina

Gobernador Castello Airport serves Viedma, the capital of Argentina's Rio Negro province, situated near the mouth of the Rio Negro river in Patagonia. VDM connects this administrative center to Buenos Aires and other Argentine cities, supporting government, agricultural, and tourism traffic. Viedma has occasionally been proposed as an alternative national capital due to its central geographic position, adding a layer of political significance to the city. The surrounding region features irrigated valleys producing fruit and vegetables amid otherwise arid Patagonian steppe. VDM's relatively modest infrastructure reflects the city's role as a regional rather than major international hub within Argentina's transportation network.
