Hemingway-Boulders Wilderness Area

The Hemingway-Boulders Wilderness Area is a protected region within the Sawtooth National Recreation Area, part of the larger Sawtooth National Forest. In total, the Hemingway-Boulders Wilderness Area spans 67,998 acres across the state and was established back in 2015. The Boulder Mountains make up much of the wilderness and are home to Idaho’s highest and most rugged mountains. This remote stretch of land is both rich with history and abundant with present day wildlife. The wilderness gets its name from the Boulder Mountains as well as the famous writer Ernest Hemingway who once lived in nearby Ketchum, Idaho.

Hemingway-Boulders Wilderness Area

There are 5 named mountains in the Hemingway-Boulders Wilderness Area. The highest and the most prominent mountain is Ryan Peak at 11,699 feet. Other notable peaks include Glassford Peak, Galena Peak, and Silver Peak. The region has 12 summits that reach over 11,000 feet. The wilderness is known for its complex geography. The mixture of granite and Challis Volcanic give way to loose rock facings. These conditions give the mountains their distinctive ruggedness but severely limit the amount of rock climbing.

The most abundant type of wildlife in the wilderness is mountain goats, who roam throughout the land. Other inhabitants include gray wolf, mountain lion, elk, moose and the elusive wolverine. Chinook salmon and various species of trout run through the waters of the wilderness. Within the Hemingway-Boulders Wilderness Area, lie the headwaters for the East Fork of the Salmon River and the Big Wood River. The landscape that makes up the wilderness is often associated with nearby White Cloud Wilderness and the Jim McClure-Jerry Peak Wilderness. There are just 29 miles of designated trails throughout this rugged landscape. While hikes take to these trails, the limited amount often leads to off trail adventuring and summiting the rugged peaks.

Major Trails and Hiking Areas

North Fork of the Big Wood River: This 8-mile out and back hike has 1,640 feet of elevation gain. The trail follows along the river, through forested sections intermixed with open and rolling fields. The surrounding peaks rise above the valley with their rugged peaks. In the summer months, wildflowers fill the fields.

Galena Peak: At 11,138 feet, Galena Peak is the third tallest in the entire wilderness. The trail to the top is no easy route, totaling 4.8 miles out and back with 3,536 feet of elevation gain. Much of the trail follows the ridgeline up the side of the mountain, with loose rocks underfoot. The beginning section of trail climbs through the forest before revealing the summit in the distance. From the top, hikers have panoramic views of the wilderness, nearby wilderness areas, and the Sawtooth National Forest.
