Hunters report mixed experiences with Idaho's Unit 66, emphasizing rugged terrain that demands good physical conditioning and careful planning. Many appreciate the unit's diverse habitat supporting elk and deer, but advise paying close attention to draw odds due to the high competition for tags. The seasonality is described as unpredictable, with weather conditions changing rapidly, which can impact game movement and accessibility in the area. While some hunters have found success by adapting strategies based on changing conditions, newcomers should be prepared for challenging hunts and variable success rates.
