GOHUNT's Hunting Unit Profiles for Unit 21A, Idaho, revealed a few key insights for hunters considering this area. Firstly, it’s clarified that the late muzzleloader tag is only valid for Unit 21A, correcting earlier misinformation about it being valid in adjoining units. Hunters generally find the terrain favorable for using horses to access more remote areas and avoid crowded trails from ATV use. Additionally, there are reports indicating a significant presence of antelope, but with a need to strategize around potential hunting pressure and access to private lands. Engage with seasoned locals like fellow hunters offering their contacts for valuable firsthand advice and scouting tips.
