Mariposa Yosemite Airport (RMY)

Mariposa-Yosemite Airport (IATA: RMY, ICAO: KMPI, FAA: MPI) serves as the premier general aviation gateway to Yosemite National Park, strategically positioned four miles west of Mariposa, California, at 2,250 feet elevation in the scenic Sierra Nevada foothills where this public facility owned by Mariposa County enables direct access to one of America's most iconic national parks. The airport's proximity to Yosemite's dramatic granite cliffs, waterfalls, giant sequoia groves, and diverse wildlife makes it an essential transportation hub for private pilots, charter operations, and aviation enthusiasts seeking efficient access to world-renowned natural attractions while avoiding the congested highway approaches that characterize peak tourist seasons.

Operational infrastructure centers on a single 3,305-foot asphalt runway (8-26) designed to accommodate general aviation aircraft ranging from light sport planes to business jets, with comprehensive services including 100LL and Jet-A fuel availability, professional tie-down services, and essential pilot amenities. The facility operates on CTAF frequency 122.7 and maintains pilot lounge facilities for flight planning and relaxation, plus restroom facilities and aircraft parking services supporting extended visits to the Yosemite region. AirBorrn Aviation Services, LLC operates as the locally-owned Fixed Base Operator, providing specialized services for pilots navigating the unique challenges of Sierra Nevada mountain flying including weather monitoring, flight planning assistance, and local area knowledge essential for safe operations in complex terrain.

Geographic significance encompasses the airport's role as a crucial component of California's general aviation infrastructure, enabling efficient access to Yosemite National Park while supporting tourism, emergency services, and regional connectivity in the economically vital Central Sierra region. The facility serves private aircraft owners, charter companies, and flight training operations, including Yosemite Airways providing scenic flights and specialized aviation services designed to showcase the Sierra Nevada's spectacular landscape from unique aerial perspectives. Mountain flying conditions require particular attention to density altitude effects, weather patterns, and terrain clearance, making the airport an important training environment for pilots developing high-altitude and mountain flying proficiency.

Historically, the airport developed alongside Mariposa County's evolution from Gold Rush-era mining community to modern gateway for Yosemite tourism, adapting to serve recreational aviation that supports the region's economy while maintaining the authentic Sierra Nevada character that attracts visitors from around the world. The facility contributes to emergency medical services, fire suppression operations, and government services essential for remote mountain communities, while tourism-related flights provide economic benefits supporting local businesses and employment in this economically challenged rural region that depends heavily on Yosemite-related visitor spending for economic sustainability.
