About Yellowstone Airport

Overview

Yellowstone Airport serves the West Yellowstone region, providing critical access to Yellowstone National Park and surrounding wilderness areas. Located at a high elevation of 6,649 feet MSL, this medium airport is strategically positioned near the Wyoming-Montana border, supporting general aviation, charter, and seasonal tourism operations.

Flying Conditions

The airport experiences predominantly VFR conditions, with 89.5% of observations showing favorable visual flight rules. Southwest winds prevail at an average of 9 knots, with occasional gusts up to 24 knots, and calm conditions occurring 48.7% of the time. Temperature variations are significant, ranging from -11°C to 24°C, with an average of 7.1°C, which can impact aircraft performance.

Notable Features

Situated in a mountainous region, Yellowstone Airport's high elevation and surrounding terrain demand careful flight planning and performance calculations. The single runway (01/19) is 8,399 feet long with an asphalt surface, providing ample length for most aircraft operations. Pilots should be prepared for potential mountain flying challenges and rapidly changing weather conditions typical of the Greater Yellowstone ecosystem.

Approach Considerations

With a 100% favorable wind condition for runway 01/19 and an average crosswind of just 4.1 knots, the airport offers consistent approach opportunities. September and October represent the most reliable VFR months, with excellent visibility averaging 9.8 statute miles. Pilots should remain vigilant about potential mountain weather effects and prepare for quick meteorological transitions common in high-altitude mountain airports.
