CO Bighorn Sheep Unit S37 — ST. VRAIN

CO S37 – ST. VRAIN. Terrain & Access St. Vrain spans 5,261–13,207 feet across 194,747 acres with strong public-land access (78% public).

A 20% wilderness designation means some terrain requires backcountry navigation, but a majority of the unit remains road-accessible or lightly developed.
