Glacier Peak Wilderness

Glacier Peak Wilderness is a protected area spanning over 566,000 acres with dense forests, steep valleys, and numerous glacial formations throughout. The 10,541-foot volcano at its center rises dramatically above the surrounding peaks and valleys.

The area was protected in 1960 by the North Cascades Conservation Council, four years before the national wilderness legislation took effect. This early designation made it a pioneer in the movement to protect wild lands.

Indigenous peoples maintain deep ties to this land that reach back through generations. The wildlife inhabiting these forests and peaks, from black bears to mountain goats, shapes how people understand and relate to the place.

Access is only by foot since no roads lead directly into the wilderness, and the terrain requires careful navigation. Most trails become clear of snow by mid-August, making this the best window for serious hiking trips.

This wilderness recorded the last confirmed grizzly bear sighting in the United States portion of the North Cascade ecosystem. That rare encounter marks an important moment in how the region's wildlife populations have changed over time.
