Padre Aldamiz International Airport (IATA: PEM, ICAO: SPTU) serves Puerto Maldonado, the capital of the Madre de Dios region in southeastern Peru. It is the primary air link for a remote Amazonian city that lies near the confluence of the Tambopata and Madre de Dios rivers. The airport plays a critical role in regional connectivity, as road access to Puerto Maldonado can be difficult and time-consuming. It supports tourism to the Tambopata National Reserve and the Manu Biosphere Reserve, two of the world's most biodiverse ecosystems. The facility was upgraded in the early 2010s to handle increased passenger traffic, particularly following improvements to the Interoceanic Highway connecting Peru with Brazil, which boosted economic activity in the region.
