Mariana Grajales Airport — Guantánamo, Cuba

Mariana Grajales Airport (GAO) serves Guantánamo in eastern Cuba, a city distinct from the US naval base of the same name located further south on the bay. Named after a revered figure in Cuban independence history, the airport primarily handles domestic flights connecting Guantánamo to Havana, supporting regional travel in an area otherwise reached mainly by long road trips across the island. GAO sees relatively light traffic compared to Cuba's international tourist airports, reflecting its role as a provincial rather than resort destination. The surrounding region is known for its mountainous terrain and distinct Afro-Cuban cultural heritage, drawing more domestic travelers and occasional researchers than international tourists to this modest regional facility.
