Overview of CO GMU 66 Hunting Facts

Nestled in the Gunnison Basin of southwestern Colorado, Unit 66 is a prized hunting unit that has been overlooked. Despite its trophy elk and deer that are taken from the unit every year and the healthy herd populations, this unit is not heavily hunted like other units in Colorado. The Powderhorn Wilderness, Uncompahgre National Forest, La Garita Wilderness and Gunnison National Forest all contribute to the nearly 450,000 acres (78%) of public land that Unit 66 has to offer. In addition to the vast expanse of wilderness, Unit 66 contains several perennial springs and numerous lakes. Wildlife do not have to look far for food, water, cover or bedding. This abundance of natural resources may help narrow down your hunting area. Another reason unit 66 has been able to maintain its status as a lightly hunted unit is that there are no OTC elk tags or antelope tags issued.

CO Unit 66 Species Hunting Info

INFO: Mule Deer Hunting in Colorado Unit 66
Contributing to the healthy deer numbers is the resident Powder horn Creek deer herd which carries a population of approximately 5,000 deer. The unit provides bountiful resources that can sustain the deer’s needs year-round. What that means to hunters is that the probability of the deer moving out of the unit as seasons change is low. Through tactful preparation and sometimes a stroke of luck, hunters will close in on the herds and their daily patterns. Unit 66 is a stand-alone unit for mule deer tags. The archery and muzzleloader seasons are straight buck tags with no doe tags allotted. Second and third rifle seasons are valid for hunting either sex. Fourth rifle season contenders can only draw a buck tag for unit 66.

INFO: Elk Hunting in Colorado Unit 66
The variety of terrain and the low hunting pressure of Unit 66 allow the Lake Fork Elk Herd (6,000 population) to flourish in this environment. The sound elk numbers and ability for hunters to get away from the crowds make this unit almost too good to be true. The terrain can be challenging as elk like to retreat to the remote areas. In this case, the remote areas can be an uphill climb. However, motorized vehicles and horseback are permitted in certain areas and can be of great service for navigating through Unit 66. The elk tag regulations are very straightforward for unit 66. For all seasons (archery, muzzleloader, 1st rifle, 2nd rifle, 3rd rifle and 4th rifle), the tags are valid for hunting elk of either sex.
