Choosing an airfield here
What drives the choice in this area: where the traffic goes, where you can clear, and what you can land.
Overview
10 airfields serve Sun Valley. Friedman Memorial (KSUN) handles the most business aviation traffic, with 73% of the area's business jet movements , followed by Joslin Field / Magic Valley Regional and Jerome County . The area spans south central Idaho, from the Sawtooth valley floor near Stanley down to the Snake River plain around Twin Falls and Burley. Friedman Memorial (KSUN) sits at 5,320 feet in the Wood River Valley, while several outlying strips near Challis, Mackay, and Stanley run past 6,000 feet elevation, so density altitude and terrain routing shape planning more than distance does. No airport in the area has customs on site. Winter brings mountain-wave and valley wind considerations around Sun Valley, while July traffic reflects the summer resort season.

Business jet movements across the Sun Valley area reached 2,407 in July 2025, the peak month, against a low of 900 in April. That is roughly a 2.7-fold swing between the slowest and busiest months. Five months of the year run above the 1,475 average monthly figure, with July, August, and the winter months of December through March carrying most of the load. Operators planning ramp space or fuel uplift around Friedman Memorial (KSUN) and nearby fields should size for the summer peak rather than the annual average, since ground handling and parking pressure concentrate heavily in that window.
Airports in the Sun Valley area range from 3,732 feet at Gooding Municipal (KGNG) up to 6,403 feet at Stanley (2U7), a difference that affects takeoff performance planning across the area. Friedman Memorial (KSUN), the busiest field, sits at 5,320 feet, already high enough to matter for density altitude on warm days. Joslin Field/Magic Valley Regional (KTWF) and Jerome County (KJER) sit lower, near 4,000 to 4,150 feet, on the Snake River plain. Crews moving between the mountain fields and the plain fields should expect meaningfully different runway performance margins for the same aircraft weight.
Joslin Field/Magic Valley Regional (KTWF) in Twin Falls and Jerome County (KJER) in Jerome sit 15 NM apart, the closest pairing among the area's larger public fields. Both carry Jet A and sit on the Snake River plain at similar elevation, roughly 4,150 and 4,050 feet respectively. KTWF holds the area's longest paved runway at 8,704 feet and has a control tower, while KJER is untowered with a 5,002-foot runway. For operators working the Magic Valley side of the area, this short separation gives a nearby alternate without a change in terrain or elevation profile.
Friedman Memorial (KSUN) in Hailey recorded 12,843 business jet movements, accounting for about 73% of all business aviation activity tracked across the Sun Valley area. It is a towered field with Jet A available and a 7,550-foot paved runway, sitting less than a mile from the area's reference point. The next-largest field, Joslin Field/Magic Valley Regional (KTWF) in Twin Falls, logged 3,025 movements, less than a quarter of the KSUN figure. This concentration means ramp and parking constraints at KSUN during peak periods carry more operational weight for the area than conditions at any other field.
Three airports in the Sun Valley area have paved runways of 6,000 feet or longer: Joslin Field/Magic Valley Regional (KTWF) at 8,704 feet, Friedman Memorial (KSUN) at 7,550 feet, and Arco-Butte County (KAOC) at 6,610 feet. KTWF and KSUN are both towered and stock Jet A, while KAOC is untowered and does not carry Jet A on field. For aircraft with longer runway requirements, KAOC remains an option for landing but not for a jet fuel uplift, a distinction that matters when Arco is being considered as a fuel stop rather than a destination.
