Colorado deer seasons, 2026
Colorado's 2026 mule deer seasons are archery September 2–30, muzzleloader September 12–20, and rifle across the four fall seasons — but deer is fully open only in the second (Oct 24 – Nov 1) and third (Nov 7–15) rifle seasons. In the first and fourth rifle seasons deer is offered only through a limited optional-deer license. CPW 2025–2029 Season Structure
Colorado deer hunting is almost entirely limited (draw) — even the archery and rifle seasons that are over-the-counter for elk generally require drawing a deer tag. The dates below are the statewide framework from the full calendar; your hunt code sets your actual window.
Season dates as a table
| Species | Method | 2026 dates |
|---|---|---|
| Deer | Archery | SEP 2 – SEP 30 |
| Muzzleloader | SEP 12 – SEP 20 | |
| Rifle (1st–4th) | OCT 14 – OCT 18 (1st); OCT 24 – NOV 1 (2nd); NOV 7 – NOV 15 (3rd); NOV 18 – NOV 22 (4th) |
Deer in the rifle seasons — the part people get wrong
Deer and elk share the four rifle seasons, but not equally:
- 2nd & 3rd rifle — the full combined deer-and-elk seasons. This is when most rifle deer hunting happens.
- 1st & 4th rifle — elk-primary. Deer is available only through a separate limited optional-deer license, not the general season.
So "is deer season open in first rifle?" has a genuinely nuanced answer, and it's the kind of thing the older Colorado hunting sites blur. The rifle-seasons page lays out all four.
Archery and muzzleloader
Archery deer runs the full month of September 2–30, overlapping the elk archery season; archery rules and crossbow details apply the same as for elk. Muzzleloader deer is the short September 12–20 season and is limited (draw), with its own equipment rules.
The deer rut
Unlike elk, the mule deer rut comes late — mid-to-late November — which is part of why the fourth rifle season and late plains seasons are prized by deer hunters even though they're cold and hard to draw.
Drawing a deer tag
Because deer is largely limited, preference points matter, and the draw is how you get most deer tags. Non-residents should read the non-resident guide for the caps that apply.
Common questions
When is deer season in Colorado in 2026?
Archery deer opens September 2 and runs through September 30. Rifle deer falls in the four fall seasons between October 14 and November 22, with the second (Oct 24 – Nov 1) and third (Nov 7–15) being the main combined deer-and-elk seasons.
Is deer season open during first rifle in Colorado?
Only through a limited optional-deer license — the first rifle season (October 14–18) is elk-primary. The second and third rifle seasons are the full combined deer-and-elk seasons.
Do you need to draw a tag to hunt deer in Colorado?
Almost always, yes. Unlike elk, Colorado deer hunting is largely limited (draw only), so you generally need to apply in the draw and may need preference points for better units.
