What To Hunt (& Where To Hunt) In Costilla County, CO

Costilla County, couched within the San Luis Valley in south-central Colorado, stretches over almost 1,227 square miles. With the arrival of Europeans in the late 1600s, it became formally established on April 5, 1851, and remains the oldest continuously occupied settlement in Colorado.


The county attracts a lot of Americans looking to build an off-the-grid homestead because land prices are reasonable and, despite low precipitation, it’s well suited for crop cultivation and the raising of livestock.

Costilla County also teams with wildlife, making it a prime destination for hunters and fishermen.

Fishing in Costilla County

The Rio Grande, one of Colorado’s best-known rivers, snakes its way through southern Colorado. With many good access points to the river, the river attracts many fishermen and has a robust fly-fishing community. Not only is it a fun place to fish, but it’s also home to some large trout, too–the Grande Truchas!

The headwater of the Rio Grande starts at around 12,000 feet elevation in the majestic San Juan Mountains. The river runs through forest land for the first 25 miles and the water is mostly wadable. A lot of varieties of trouts live in these waters, including some surprisingly big browns.

Traveling further down the river toward South Fork about 30 miles, there’s a mix of public and private land. You can access the river, however, from the US forest and Colorado State Wildlife Areas. These spots are ideal for dry fishing in the summertime when hatches abound and the water is low.

Hunting GMU 83

Colorado is broken up into game management units, and the GMU with one of the largest elk herds is GMU 83, located in Costilla County. The Trinchera elk herd has an estimated population of around 7,000 elk. Deer and antelope are also abundant in the area, and it holds a large population of grouse.

GMU 83 has over 4,500 acres of common land that can be used by owners for hunting. And hunting is allowed with permission. However, Colorado law prohibits shooting within a quarter mile of occupied land or shooting across roads.

Also, GMU 83 allows archery and muzzle-loaded hunting every year in September. Many hunters have had great success harvesting prize worthy elk.
