It’s a TRACON takeover in the Northern Rockies! Bozeman (KBZN) and Boise (KBOI) may be hundreds of miles apart, but both fall under the watchful eyes of the Big Sky TRACON; one radar facility with one name and one mission: keeping mountain traffic moving safely and smoothly. For one day only, ZLC is lighting up both ends of this vast and scenic airspace, bringing top-to-bottom coverage to two of the West’s busiest Class C airports.

From the Gallatin Valley to Idaho’s high desert, Big Sky Bash invites pilots to experience a true crossfire through mountainous terrain, dynamic airspace, and full-service ATC from Big Sky TRACON and Salt Lake City Center. Whether you’re flying a VFR hop through the valleys or pushing high-altitude IFR across the divide, this event showcases the best of western U.S. flying; all under the Big Sky.

Come bash through the skies with us; bring your best traffic calls, your best crosswind landings, and remember — it’s not Boise Approach. It’s Big Sky.
