Challis Airport (CHL)

Challis Airport (CHL), also known by its ICAO code KLLJ and FAA LID LLJ, is a premier general aviation facility serving the city of Challis and Custer County in the rugged Salmon River Mountains of central Idaho. Situated at an elevation of 5,072 feet, the airport acts as a critical gateway for 'backcountry' aviation, providing essential access to some of the most remote wilderness areas in the lower 48 states. The facility is city-owned and plays a fundamental role in the regional economy, supporting tourism, government land management, and local commerce.

The airport's infrastructure is specifically designed to support high-altitude mountain operations, featuring a single 4,600-foot asphalt runway (17/35) that is well-maintained year-round. While the terminal facilities are modest compared to major commercial hubs, they provide a high level of service for the general aviation community. Facilities include a sheltered passenger waiting area, restrooms, and a dedicated pilot's briefing room equipped with an Automated Surface Observing System (ASOS) for real-time mountain weather updates. For the convenience of aircraft operators, the airport offers 24-hour self-service fueling for 100LL Avgas and Jet A, as well as oxygen services and on-site aircraft maintenance.

Currently, Challis Airport is a bustling center for regional air taxi services and specialized charters. It serves as the primary base for Middle Fork Aviation, which provides daily flights into the Frank Church-River of No Return Wilderness. The airport is also a vital link for several government agencies, supporting wildland firefighting logistics, game studies, and search and rescue operations. While no scheduled commercial airlines serve the airport, it remains an indispensable node for private pilots and outdoor enthusiasts visiting the region for world-class rafting and hunting. Ground transportation into central Challis, located just a mile away, is typically arranged via local taxis or lodge shuttles, ensuring easy access to the city's hotels and traditional mountain dining.
