Challis Airport sits in Challis, Idaho in a high mountain valley. Field elevation is 5,075.9 ft MSL. The airport has one runway, 17/35, which is 4,601 ft long with an asphalt surface. No tower is published. CTAF and UNICOM are both 122.8.

No ILS approaches are published for KLLJ. Pattern altitude is not published, so use the standard 1,000 ft AGL for light piston operations unless current published data says otherwise. Middle Fork Aviation is on the field. It carries 100LL and Jet A. Call them at (208) 879-5728 for current service details.

The Chart Supplement remarks matter here. Deer are on and near the airport. Helicopter traffic can be active near the southeast end. The airport also has an automated weather station on site. Runway 17 is the recommended landing runway when wind permits. Runway 35 is the recommended departure runway when wind permits. Runway 17 PAPI has limits near the edges of centerline. It also becomes unusable beyond 2.5 NM from the threshold because of terrain. That terrain note is worth a close read before a first arrival. Clearance delivery is handled through Salt Lake ARTCC at 801-320-2568.
