Lake County Airport (LXV)

Lake County Airport (LXV), also known as Leadville Airport, is a world-renowned aviation facility distinguished as the highest public-use airport in North America, situated at an elevation of 9,934 feet (3,028 m). Located approximately 2 miles southwest of downtown Leadville, the airport serves as a critical gateway for mountain recreation and high-altitude flight operations in the Colorado Rockies. Its primary 6,400-foot asphalt runway (16/34) underwent a comprehensive $5.8 million reconstruction in 2020, providing a superior surface for light aircraft and corporate jets navigating the thin alpine air. The passenger experience is centered on a professional terminal building managed by the Leadville Air Center, the airport's on-site Fixed Base Operator (FBO). The facility is designed to support the unique needs of mountain aviators, offering a 24/7 accessible pilot lounge equipped with high-speed Wi-Fi, flight planning computers, and comfortable relaxation areas. A unique tradition at LXV is the presentation of a free 'Certificate of Navigation' to visiting pilots, commemorating their successful landing at this record-setting elevation. Amenities also include 24-hour self-service 100LL Avgas and Jet-A fuel, along with secure tie-down spaces and limited short-term hangar storage. Beyond standard travel, LXV is a premier global hub for high-altitude aircraft testing, frequently utilized by major manufacturers like Bell, Airbus, and various branches of the U.S. military. The airport's extreme environment, where density altitude often exceeds 13,000 feet in the summer, provides a critical laboratory for engine and aerodynamic validation. Ground transportation is well-supported by two on-site courtesy vans for local trips to Leadville's historic district, while the facility's location puts it within a one-hour drive of eight major world-class ski resorts. Travelers are strongly advised to remain mindful of afternoon mountain storms and to check aircraft performance data carefully before departure due to the significant impact of thin air on climb rates and takeoff distances.
