Unit S25

Colorado Hunting Guide — Bighorn Sheep

Unit S25 is a Colorado bighorn sheep unit with 114 applicants for 3 tags over three years, located in the rugged canyon and mountain country of the Western Slope. With extremely limited tag availability and significant applicant interest, this is a long-range preference-point target. We regard S25 as a genuine trophy sheep experience for hunters committed to building points over many years.

Where to Find Bighorn Sheep in Unit S25

Bighorn sheep in Unit S25 use the steepest, most exposed terrain in the unit — cliff faces, talus fans, and canyon walls that provide both food and immediate escape routes.

Glass All Rock

Never assume a rocky face is empty without a thorough glassing pass. Sheep can remain motionless on ledges for hours and blend into rock backgrounds nearly perfectly. A 15x-65x spotting scope is the minimum tool for effective sheep glassing.
