The Noisy-Diobsud Wilderness is a relatively small wilderness area in northwestern Washington state adjacent to North Cascades National Park. Created in 1984, the Noisy-Diobsud contains 14100 acre of steep valleys, subalpine lakes, and the summits of Anderson Butte and Mount Watson. It is part of Mount Baker National Forest. The only maintained trail enters the west side of the wilderness from the Anderson Lakes road above Baker Lake.
