Area 155 is mostly wilderness area in the Gros Ventre Wilderness. Nonresidents will be limited for access in the wilderness area, unless they use a licensed guide.For nonresidents, this area is part of Region H and tags drawn for this area are also valid in: 130, 138, 139, 140, 142, 146, 149, 150, 151, 152, 153, 154, 156.

This area has limited hunter activity and results in low hunting pressure throughout most of the season. A majority of the unit is above the treeline with many high mountain lakes and many basins that create the perfect habitat to grow trophy class bucks.

Basins and areas above the treeline will have snow all year and water sources that run all year long. Rocky fields with large grass flats and wildflowers flow down to deep canyons that lead to the lower elevations. The terrain is high in elevation and it can be difficult to get to locations where bigger deer typically are found.

Wilderness

Under Wyoming law nonresidents are not permitted to hunt big game or trophy game in any federally designated wilderness areas without the presence of a licensed guide or resident companion. The resident companion must first get a free non-commercial guide license from a Game and Fish office. The law does not prohibit nonresidents from hiking, fishing or hunting game birds, small game, or coyotes in wilderness areas.

Conifer forests are located throughout the unit, with thick patches in between rock slides. High mountain grassy meadows are in many of the draws and ridges that run through the area. Willow bushes are located around many of the high mountain lakes in basins.

Many Forest Service roads lead to the edge of the wilderness. Use horse trails to get into the main portions of the unit. Game trails will take hunters into the basins that mature bucks roam.

Hunters are typically deep into the wilderness and camping is the best option to stay near prime hunting areas. For hunters who take day trips into the area, lodging can be found just west of the unit in Jackson Hole.
