The Boulder River Wilderness is located within the Mt. Baker Snoqualmie National Forest. Created by Congress in the 1984 Washington Wilderness Act, it is nearly 49,000 acres in size. Dense, mossy forests and steep ridges rise to the ice-clad summits of Three Fingers and Whitehorse Mountain. Elevations range from below 1,000 feet to nearly 7,000 feet.

Boulder River, a tributary to the North Fork Stillaguamish, runs approximately 10 miles through the Northwest section of this Wilderness. It is a low elevation valley which often allows for year round, snowfree enjoyment of a magnificent but often forgotten part of the forest. This Wilderness also encompasses the Long Creek Research Natural Area.

Few trails exist in this wilderness, but its beauty and solitude is worth the effort.

• Hike among ancient trees and lush, overgrown brush and ferns.
• Enjoy the rough terrain of this untouched, pristine valley.
• Backpack into the wilderness to camp in the solitude of tall, quiet trees.
