Santa Izabel do Morro Airport (IDO)

Santa Izabel do Morro Airport, identified by the IATA code IDO and ICAO code SWIY, is a unique regional aviation facility serving the Iny Karajá Indigenous Village on Bananal Island, within the state of Tocantins, Brazil. Situated on the world's largest fluvial island between the Araguaia and Javaés Rivers, the airport stands as a critical lifeline for this remote community. It provides an essential aerial gateway for regional administration, health services, and the promotion of sustainable ecotourism within the Araguaia National Park. The airport features a modest but functional physical infrastructure tailored for regional operations, consisting of a single 1,540-meter asphalt runway. While the facility lacks a traditional commercial passenger terminal with large-scale retail or dining, it offers a vital operations base for domestic regional traffic and government missions. The airfield operates under Visual Flight Rules (VFR) during daylight hours, providing a reliable transport link in an area where land access is seasonally restricted by river levels and environmental conservation regulations. Travelers should note that amenities are basic, and the facility reflects the remote and culturally significant nature of its location on the edge of the Amazon and Cerrado biomes. Flight operations at Santa Izabel do Morro are primarily managed through private charters, government transport, and specialized air taxi services, as there are currently no consistent scheduled commercial airline connections to major hubs. The airport serves as a vital base for the Brazilian government's Indigenous health and protection missions, facilitating the transport of essential supplies and medical personnel. Ground transportation from the airstrip is primarily via local community vehicles or small boats traversing the Araguaia River, providing access to the village center and nearby ecotourism camps. The facility remains a cornerstone of the regional transport network, ensuring that the isolated communities of Bananal Island remain connected to the state's wider infrastructure.
