Fire restrictions

This unit's own agency alerts list no fire restriction as of Oct. 5, 2026. We do not check a statewide fire-order feed for CO, so that is not a statement that no order exists, and not a green light for a fire. Check with the land manager and your county before you light anything.

County and local burn bans may also apply on private, state, or county land nearby. On federal land, follow the land manager's order; off it, follow the strictest county or local rule that applies. When both touch your trip, obey both.
