Lemhi County Airport — Salmon, United States

Lemhi County Airport, identified by the code SMN, serves the small mountain town of Salmon in central Idaho. Tucked into the Lemhi Valley along the Salmon River, this general aviation facility supports recreational flying, wildfire firefighting operations, backcountry access, and medical evacuation flights for a remote region with limited road connectivity. The surrounding terrain of steep ridgelines and narrow valleys makes SMN an important link for outdoor enthusiasts heading into the Frank Church-River of No Return Wilderness. The airport features a single paved runway capable of handling small fixed-wing aircraft. Given Salmon's isolation from major population centers, Lemhi County Airport plays an outsized role in emergency response and seasonal tourism traffic tied to whitewater rafting and hunting.
