Lake County Airport: The Highest Paved Public-Use Airport in the United States
LXV — Flying at 9,927 Feet in the Sky Above Leadville, Colorado
Lake County Airport (LXV) near Leadville, Colorado holds a distinction that no other airport in the United States can claim: it is the highest paved public-use airport in the nation, perched at an extraordinary 9,927 feet above mean sea level in the high mountain basin above the historic mining city of Leadville. This elevation — essentially 10,000 feet above the sea — creates aviation conditions so extreme that operating at LXV is considered among the most demanding general aviation challenges in the continental United States, surpassing even many mountain airports that pilots approach with significant trepidation.
The aeronautical implications of operating at nearly 10,000 feet are profound and unforgiving. Density altitude on a standard summer day can reach 12,000-13,000 feet or higher, dramatically reducing the performance of normally aspirated piston engines — which lose approximately 3% of power per 1,000 feet of altitude gain above sea level — to levels that can make operations with heavily loaded aircraft dangerous or impossible. Turbocharged engines fare better but still experience significant performance degradation. Propeller efficiency decreases. The aerodynamic lift generated by wings and control surfaces diminishes. Takeoff rolls become dramatically longer than sea-level reference distances, and climb rates after liftoff can be surprisingly anemic even for aircraft that perform comfortably at lower Colorado airports. Pilots who have flown at Centennial Airport (5,883 ft) or even Gunnison (7,680 ft) must recalibrate their entire frame of reference for performance expectations at LXV's altitude.
Despite — or perhaps because of — these extraordinary challenges, Lake County Airport attracts aviation enthusiasts who seek the unique experience of operating at America's highest paved public-use airport. The surrounding landscape is spectacular: Leadville itself is America's highest incorporated city at 10,152 feet, ringed by Colorado's two highest peaks (Mount Elbert at 14,433 feet and Mount Massive at 14,421 feet), with the Arkansas River headwaters flowing south through the valley below. The Colorado Division of Aeronautics provides specific safety guidance for operations at LXV, and pilots planning their first visit are strongly advised to study airport-specific performance data, consult with pilots experienced at LXV, and plan their visit for early morning hours when cooler temperatures reduce density altitude to more manageable levels.
International Airports
An international airport is a vital component of any major metropolitan area. It connects domestic and international travelers, providing them with a means to connect to the rest of the world.
An international airport is a large airport that is equipped to handle both domestic and international flights. It also has a significant economic impact on the local community.
These major Colorado Airports generate thousands of jobs and contribute billions of dollars to the local economy through tourism and other related industries.
A large international airport also offers a variety of amenities for travelers. These can include shopping centers, dining options, lounges, and other services such as currency exchange and luggage storage.
Private Airports
Private airports, also known as general aviation airports, are airports that are not open to commercial airlines and are used primarily by private aircraft.
One of the main benefits of a private airport is the exclusivity and privacy it offers.
These airports are often used by high-profile individuals, such as celebrities and business executives, who value their privacy and want to avoid the crowds and security lines of commercial airports.
Private airports also offer more flexibility and convenience for aircraft owners. They can also be used for training pilots and hosting aviation events.
There are 0 Private Airport in Leadville, Colorado.
Regional Airports
Regional airports are smaller airports that serve a rural geographic region, such as a smaller city or county with a population of less than 100,000.
Small airports mostly offer flights within the same country, but some may offer flights to nearby countries.
One of the main advantages of regional airports is their convenience. They also tend to have shorter security lines and fewer crowds, making the overall travel experience more enjoyable.
There are 0 Regional Airport in Leadville, Colorado.
Municipal Airports
Municipal airports which are also called "public airports" are owned and run by local governments like cities and counties.
Most of the time, they are smaller airports that serve a certain area and have mostly domestic flights, but some may also have flights to nearby countries.
One of the main advantages of municipal airports is their accessibility. They are often located in or near major cities, making them a convenient option for travelers.
Municipal airports provide a vital link for businesses in the region, allowing them to easily connect to other parts of the country.
There are 0 Municipal Airport in Leadville, Colorado.

Lake County Airport (LXV): America's Highest Paved Airport — Critical Facts for Pilots
Lake County Airport (LXV) at 9,927 feet is the highest paved public-use airport in the United States, creating aviation conditions unlike any other public airport in the nation. Pilots must conduct thorough performance calculations for every operation at LXV, accounting for dramatically reduced engine power, propeller efficiency, and aerodynamic performance. Early morning arrivals and departures — when temperatures are lowest and density altitude is most manageable — are strongly recommended. Vail Eagle County Regional Airport (EGE) approximately 25 miles northwest and Gunnison-Crested Butte Regional Airport (GUC) approximately 40 miles south provide alternative airports with comprehensive GA services if LXV operations are not feasible on a given day.
Leadville itself is America's highest incorporated city at 10,152 feet — higher than the airport. The town's mining heritage (the Healy House Museum, Tabor Opera House) and its Colorado Trail access make it a bucket-list destination for pilots who have prepared adequately for LXV's extraordinary operating conditions.
Frequently Asked Questions
How high is Lake County Airport at Leadville?
Lake County Airport (LXV) sits at 9,927 feet above mean sea level — the highest elevation of any paved public-use airport in the United States. This extraordinary altitude creates density altitude conditions that can exceed 13,000 feet on warm summer afternoons.
What aircraft can safely operate at LXV?
LXV is accessible to turbocharged aircraft and some high-performance normally aspirated aircraft when operated conservatively, typically with reduced loads and during cooler morning hours. Pilots must compute takeoff and landing performance carefully using the actual density altitude, not pressure altitude. Many normally aspirated piston aircraft should not attempt operations on warm days at LXV without formal high-altitude training and careful analysis.
What is the best time of day to fly into LXV?
Early morning operations — before 10 AM — are strongly preferred at Lake County Airport. Lower temperatures in the morning hours reduce density altitude significantly compared to afternoon operations, providing substantially better aircraft performance margins for takeoff, climb, and go-arounds if needed.
What training is recommended before flying to LXV?
Formal mountain flying training that specifically addresses high-density altitude airport operations is strongly recommended before attempting operations at Lake County Airport. The Colorado Division of Aeronautics provides guidance, and several Front Range flight schools offer high-altitude mountain flying courses that include LXV-specific preparation.
