World Class Fly Fishing Event.
A Premier Fly Fishing Fundraising Event
Every September in Jackson Hole, Wyoming, teams put their skills to the ultimate test – each participant fishing two days with a single fly pattern each day. Since 1986, the Jackson Hole One Fly has united passionate anglers from around the world with premier regional guides in a unique event that celebrates the sport while raising funds for critical trout habitat conservation.
2025 Event
September 4th-7th, 2025
Join us for the 39th annual Jackson Hole One Fly on the legendary Snake River and South Fork. Forty teams of four anglers each will take part in this invitation-only tournament, with one cardinal rule: choose your fly wisely – you get only one pattern per day. Lose it, and your scoring day is done.
The event features guided drift boat fishing on premium river sections, real-time scoring updates, evening social events, and culminates in our awards ceremony and conservation fundraising dinner.
