Peters Mountain Wilderness, Protected wilderness area in Giles County, Virginia, US.

Peters Mountain Wilderness is a protected area in Giles County, Virginia that covers mountainous terrain with sandstone outcroppings, mountain bogs, and forests of oak and hickory trees. The landscape presents a mix of different habitats and geological features that shape the hiking experience.

Congress designated the Peters Mountain Wilderness in 1984, and the Forest Service manages it. The area lies on Peters Mountain in the Jefferson National Forest, about 10 miles north of Pearisburg, Virginia, and straddles the Virginia–West Virginia line. Loggers last cut the area in the 1920s and 1930s, leaving a 10-acre stand of old-growth hemlocks.

The Appalachian Trail passes through this wilderness and connects hikers to a broader network of mountain paths. This route is part of a long-standing hiking tradition that attracts people from around the world.

The National Geographic Trails Illustrated Map 787 provides detailed navigation information for the entire region and surrounding valleys. Good preparation with maps is important since the trails are remote and conditions change with the seasons.

Peters Mountain mallow was found in 1927, when botanists counted 50 specimens; a 1986 survey located only four, and the plant was listed as endangered that year. Dormant seeds need fire to crack their coats, and after a small blaze in 1992 a few sprouted, followed by 500 seedlings. A 398-acre Nature Conservancy preserve just outside the wilderness protects it.
