You may take one mountain lion, either sex, per license year (April 1–March 31). Hunters may harvest one lion in the month of April or one lion during the fall season, which starts at the end of November and runs until the end of March the following year, depending on the valid season dates for the unit you are hunting. Not every unit is open for both sets of season dates. Furthermore, each hunting unit has its own total harvest limit. You must check daily to make sure the unit you want to hunt is open. Units close when harvest limits are reached. It is illegal to hunt (pursue or harvest) a mountain lion in a unit after it has closed. Dogs are permitted in Colorado and possess their own set of limitations.
