This unit is mostly remote, hard-to-reach roadless terrain in the Middle Fork of the Salmon River drainage. Moose tags are easier to draw because hunter success is low.

Moose hunting is difficult in this unit as evidenced by low hunter success.

One of the most remote and isolated wilderness units in the West, Unit 27 consists of a large part of the Frank Church-River of No Return Wilderness in the Challis and Payette national forests. The Middle Fork of the Salmon River runs up through the middle of the unit and skirts the northwest edge before dumping into the Main Salmon River about 40 miles west of Salmon. Land is mostly mountainous with some large canyons and steep, rugged mountains, including Mount Wilson, which is 9,580 feet above sea level, Puddin Mountain at 9,684 feet, Aggipah Mountain at 9,920 feet and Mount McGuire at 10,082 feet.

Much terrain is open, consisting of grassy slopes with scattered brush or timber patches, high mountain meadows, alpine basins, and high, rugged and rocky mountains. North and east facing slopes and deep draws are mostly timbered with spruces, pines and firs. Some areas have been burned by forest fires and are ideal for game with grass and browse plants taking hold as new trees begin to grow. Old growth forests are mostly sterile, supporting few moose but providing a great deal of escape cover.

The vast majority of land is roadless, but hunters can each various access points in several ways. A mining district and several trailheads in the south can be reached by ATV or four-wheel-drive vehicle. The Seafoam Ranger Station, some lakes and several mines can be reached on forest roads that are accessible from Highway 21 north of Stanley. Hunters also can drive from Warm Lake on Forest Road 579 to reach Forest Roads 447 (Burnt Logging Road) and then the Lucky Lad Road (Forest Road 447E).

Some hunters in areas with roads outside the wilderness camp along dirt roads. No towns are close enough to make motel lodging a reasonable option. Most guided hunters or those with pack strings often stay in wall tent camps. Do it yourself hiking hunters use backpack-style tents or bivouac tents and are allowed to camp almost anywhere in the wilderness.
