About Us

Can you imagine hunting a sprawling free-range South Texas Golden Triangle Ranch with 6.5 miles of Nueces River frontage?
If so, Welcome to Great Horizon Ranch.

We are seeking a limited number of discerning conservation minded sportsmen who appreciate the experience of fair chase hunting that few places can truly provide.

One of our goals at Great Horizon is to grow 200" B&C deer which requires a combination of the right habitat and deer management practices. Situated in the South Texas Brush Country located on the Webb/LaSalle County line we have the perfect mix of thick brush, abundant water and food sources to grow big mature bucks. We want to provide a high-quality hunting experience to a select group of people including friends, relatives, handicapped individuals but most importantly like-minded sportsmen.

Great Horizon is set apart by being a very special ranch specializing native South Texas deer and the fact that you never know what you may see on the ranch because of the abundance of wildlife that lives along and traverses the Nueces River. In addition to the whitetails and other game that you expect to see in South TX, we regularly see Bison, Elk, Black buck Antelope, lechwe, mountain lion, and alligators. Game birds such as Quail, Dove, Turkey and Ducks are abundant and frequent the over 100+ acres of lakes, tanks and ponds.

We at Great Horizon thank you for visiting our website and encourage you to look around and don’t hesitate to contact us when you are ready for your South Texas hunting adventure.
