Wonder Mountain Wilderness


Wonder Mountain Wilderness

This 2,349 acre Wilderness is one of the smallest wildernesses in the Western United States. Wonder Mountain Wilderness borders the Olympic National Park and is located west of Lake Cushman in Mason County. Terrain is generally rugged and ranges from a low of 1,740 feet in McKay Creek to the summit of Wonder Mountain at 4,758 feet. The lower slopes are heavily timbered with dense stands of Douglas- fir, western hemlock, and Pacific silver fir. Massive rock outcrops and precipitous pinnacles are common in the higher elevations.

Wonder Mountain is the highest peak in the Wilderness. Wonder Ponds and several other ponds are located in the high headwaters of McKay Creek. There are no rivers or major streams in the Wilderness. 

Please follow regulations and use Leave No Trace techniques to help keep this area wild, clean, and pristine.
