Hulunbuir Hailar Airport — Hailar, China

Hulunbuir Hailar Airport, known by the code HLD, serves the city of Hailar in Inner Mongolia's far northeast, acting as the principal air gateway to the vast Hulunbuir grasslands near the borders with Russia and Mongolia. The region draws domestic tourists in summer for horseback riding, yurt stays, and open steppe scenery, while winters bring brutally cold temperatures that shape both flight scheduling and airport operations. Hailar itself grew up as a trading and garrison town along historic caravan routes, and the airport has expanded over the past two decades to keep pace with rising tourism and connections to Hohhot, Beijing, and other major Chinese cities. Runway and terminal upgrades have targeted the extreme winter climate, ensuring de-icing capacity and heated facilities remain reliable even when temperatures fall far below freezing for extended stretches.
