Unit 421 in Colorado presents both opportunities and challenges for archery elk hunters, particularly with its transition to a draw unit. Many hunters report a mix of success, noting the potential for encountering bulls and substantial bear activity, but caution about the rugged terrain and unmaintained roads, which could prove tricky, especially in adverse weather. The area's remoteness means limited cell service, hence communication devices like Garmin are recommended. Those interested in hunting this unit should prepare for varying draw odds and seek further insights into allocation numbers to better strategize their hunt. Additionally, areas such as Bull Creek or Coon Creek come recommended for scouting, with many hunters emphasizing the benefit of early, in-person scouting to familiarize with the terrain and potential game activity.
