Teton County hunt numbers by species
Tags are 2026 counts for the whole hunt.
Hunts whose units reach the county in 2026 total 21, made up of 7 deer, 9 elk and 5 moose. The tag total for these hunts is 1,587 in 2026, counted by hunt rather than by county.
A second application period, August 5 to 15, covers tags left after the first draw, and controlled tags must be bought by August 1. The once-in-a-lifetime species use the 2025 and 2026 brochure dates for the 2026 hunt.
