Zone 39 covers a large chunk of the Boise National Forest northeast of Boise, including the Boise River drainage and its tributaries. The terrain ranges from moderate to steep, with timbered ridges, brushy creek bottoms, and open parks at elevations between about 3,800 and 9,000 feet. The lower western portions feature ponderosa pine, bunchgrass, and sagebrush hillsides; mid-elevations carry dense Douglas fir and mixed conifer with pockets of mountain mahogany; and the higher eastern sections transition to lodgepole, subalpine fir, and alpine meadows. Old burns and timber harvests have created productive browse areas that draw elk, particularly in the Grimes Creek, More Creek, and Crooked River drainages.
This is one of the more accessible zones for Treasure Valley hunters, and it shows — expect company on opening weekend, especially near roads. The Boise National Forest road system is extensive, with the main arteries (Idaho City road, Lowman Highway, and the Middle Fork Boise road) providing good access. Many secondary roads are gated or seasonally closed, which creates de facto walk-in areas that can hold undisturbed game. Idaho City offers fuel and limited supplies; Boise is 45 minutes to an hour west for full services. Cell service is spotty outside the Highway 21 corridor. Fall weather is variable — warm shirt-sleeve days in September, but rain, fog, and snow can roll in by early October, especially at higher elevations. The proximity to Boise makes this zone popular for weekend warriors, so plan accordingly.
Zone 39 encompasses a large block of the Boise National Forest south and east of Boise — mid-elevation timbered mountain country in the central Idaho uplands. Elevations range from about 3,500 feet in the lower Boise River canyon to 9,500 feet on the higher peaks of the Boise Mountains. The terrain is classic central Idaho: steep, timbered drainages cut by the South Fork Boise River, the Middle Fork Boise, and their tributaries, with Douglas fir, ponderosa pine, and lodgepole covering the slopes. Burned areas from multiple fire cycles create a mosaic of old growth, snag forest, and regenerating brush that elk use extensively. The lower canyon country is drier and more open, with ponderosa-grass savanna on south aspects. Zone 39 operates under a controlled hunt system — specific tags are allocated by lottery for designated hunt areas during defined seasons, which manages pressure and maintains herd quality. Elk and mule deer are the primary species, with black bears common throughout.
Access is via a network of forest roads from SH-21 (the Ponderosa Pine Scenic Byway), the Middle Fork Road, and various forest routes out of the Boise area. Some roads are paved; many are rough single-lane gravel that gets dicey with rain or early snow. Boise is the major supply hub, 1-2 hours from most hunting areas depending on which drainage you target. Idaho City, a historic mining town on SH-21, has basic services and serves as a closer staging point. Cell service works along the highways and near Idaho City, then drops in the backcountry drainages. The controlled hunt system is the key to Zone 39 — you must apply in Idaho's controlled hunt draw, and the odds vary by specific hunt number and weapon type. The controlled format limits the number of hunters in the field, which reduces pressure and generally produces better hunting than comparable general-season units. The tradeoff is the application process and the chance of not drawing. If you draw, do your homework on the specific drainage your hunt covers — the Boise NF is a big landscape and each drainage hunts differently based on its timber density, fire history, and road access.

Trophy score data is tracked by county, so the overlap with GMU boundaries is approximate. These numbers tell you whether the area is capable of growing big animals — they do not indicate public vs. private land. Big elk can come from anywhere; most elk in the lower 48 trace back to Yellowstone stock that was transplanted west after the species was nearly extirpated in the early 1900s.

Idaho Unit 39 draw odds — every hunt, by species
Odds = tags ÷ applicants for the latest year on file, per applicant pool — resident, nonresident, outfitter and every other pool the state runs. Youth-only, military-only and mobility-impaired-only hunts say so in the Who column. Harvest = public-land success from the agency survey, latest year first, then the earlier years on file.
