Hikers and horseback riders can choose from approximately 433 miles of trails in the Three Sisters Wilderness. Trailheads are located on all sides of the wilderness, in both the Deschutes and Willamette National Forests. All of the trails are clearly marked on the Three Sisters Wilderness map published by GEOGRAPHICS Inc. Over 42 miles of the Pacific Crest National Scenic Trail extend through the Three Sisters Wilderness. The Pacific Crest National Scenic Trail enters the wilderness in the south at Irish and Taylor Lakes and exits the area in the north near Dee Wright Observatory. This trail is easy to follow and regularly maintained during hiking season

The dominant figures in this wilderness, the Three Sisters and Broken Top Mountain exemplify the changes glaciers and time can bring to a volcano. The oldest of the four peaks, North Sister and Broken Top have both been severely eroded by glaciers. These two peaks form a sharp contrast to South Sister, the youngest of the four, which, because of light erosion, still retains its original conical shape. All four of these peaks are popular with mountain climbers. Difficulty levels vary, but with any of these mountains, first-time climbers should join a party led by an experienced guide. Other peaks and cones in the area include The Husband, The Wife, and Tipsoo Butte to name just a few.

There are approximately 260 miles of trail within the wilderness. The Pacific Crest National Scenic Trail traverses the wilderness for 40 miles. Most trails entering the wilderness begin in dense forests of Douglas-fir on the western slopes of the Cascades and ponderosa pine on the eastern slopes.

Total Area: 285,192 acres. Elevation Range: 2,000 ft – 10,358 ft.
