Bighorn Sheep Hunting in Unit 305-10

Where to Find Bighorn Sheep in HD 305-10

Rams in HD 305-10 occupy alpine cliff country adjacent to the Greater Yellowstone ecosystem. We glass from ridgeline vantage points above cliff bands, scanning for bedded rams in mid-morning and feeding groups on south-facing grass slopes at first light.

Much of the district is wilderness or USFS. Use FWP Plan-a-Hunt to identify trailheads, camp spots, and any seasonal access restrictions tied to the Yellowstone ecosystem.

How to Hunt Bighorn Sheep in HD 305-10

We plan HD 305-10 as a multi-week OIAL backcountry hunt. Arrive well before the opener, spike camp below ram country, and invest full days behind optics before committing to a stalk. Backup bands are essential — cliff-dwelling rams can relocate unpredictably under pressure.

Review FWP regulations for legal-ram criteria and all checkout rules. Wilderness travel demands packing discipline, and recovery from cliff country can require rope work.
