Dubois Muni sits in Dubois, Idaho. The field elevation is 5,123 ft MSL. It has one runway. Runway 16/34 is 4,600 ft long and surfaced in gravel and dirt. There is no control tower. CTAF is 122.9. No ILS approaches are published here.

Pattern altitude is not published. Use the standard 1,000 ft AGL pattern unless the current FAA Chart Supplement says otherwise. That puts the traffic pattern at about 6,123 ft MSL. This is a high-elevation field, so expect performance changes on warm days. The airport also has no winter maintenance, so surface condition matters before you go.

Published remarks call out several runway hazards. Runway 16 has a fence on the centerline near the departure end. There is also a steeple off the left side farther out. The runway edge is marked with cones and threshold panels. The strip is centered between airport boundary markers. For clearance delivery, contact Salt Lake ARTCC at 801-320-2568. No on-field FBOs are listed, so verify services with the airport operator or call the field directly before arrival.
