Glacier Peak Wilderness is a 566,057-acre (229,075 ha), 35-mile-long (56 km), 20-mile-wide (32 km) wilderness area located within portions of Chelan, Snohomish, and Skagit counties in the North Cascades of Washington. The area lies within parts of Wenatchee National Forest and Mount Baker National Forest and is characterized by heavily forested stream courses, steep-sided valleys, and dramatic glacier-crowned peaks. The dominant geologic feature of the area is 10,541-foot (3,213 m) Glacier Peak. It is the most remote major volcanic peak in the Cascade Range and has more active glaciers than any other place in the lower forty-eight states. Glacier Peak is a volcanic cone of basalt, pumice, and ash which erupted during periods of heavy glaciation.

Glacier Peak Wilderness was created by the U.S. Forest Service in 1960 through the efforts of the North Cascades Conservation Council, four years before the 1964 wilderness legislation of the Congress.

Forest vegetation comprises several species of fir, Douglas fir, hemlock, red cedar as well as stands of mixed pine and Douglas fir on its eastern slopes. Various species of wildlife inhabit the area and include deer, elk, black bear, mountain goat, cougar, marten, and lynx. Smaller animals, such as field mice are common. The last confirmed grizzly bear sighting in the United States portion of the North Cascade ecosystem occurred in this wilderness. The high mountain lakes often give good catches of fish during their ice-free months. The primary fishery is cutthroat trout, however, other species do exist.
