Selway Zone Context
Central Idaho — Selway-Bitterroot Wilderness
The Selway is wilderness elk hunting in the strictest sense — limited motorized access, dense old-growth timber, and miles between bulls. Tags are hard to draw and harvest rates are modest, but the experience is the closest thing in the Lower 48 to backcountry elk hunting at scale.
Pack-in camps, stock support, or floatplane access are the realistic options. Plan minimum 7-day trips. Permits required for wilderness use.
