Zaqatala International Airport (IATA: ZTU, ICAO: UBBY) is a small regional airport serving the city of Zaqatala in northwestern Azerbaijan, near the borders with Georgia and Russia's Dagestan region. It is situated in the foothills of the Greater Caucasus Mountains, making it a potential access point for ecotourism and nature-based travel in the area. The airport has historically seen limited scheduled commercial traffic, with operations varying over the years. It has been subject to periodic upgrades as part of Azerbaijan's broader efforts to develop regional aviation infrastructure beyond the main hub at Baku's Heydar Aliyev International Airport. Despite its international designation, Zaqatala Airport primarily serves domestic routes and has limited connectivity. The surrounding Zaqatala district is known for its forests, wildlife reserves, and hazelnut production, attracting visitors interested in the natural environment of the South Caucasus.
