Sinister Peak, elevation 8440+ feet, is a steep, glaciated peak in the remote Glacier Peak Wilderness of the North Cascades. It is situated one mile east of the larger Dome Peak at the southern edge of the massive Chickamin Glacier which drains into the cirque of Agnes Creek's West Fork. Sinister Peak is rarely visited due to its remote location, but when it is, it is commonly climbed as part of the Ptarmigan Traverse mountaineering route. The first ascent was by Lloyd Anderson, Jim Crooks, and Clinton Kelley on May 29, 1939.

Approach: Drive the Suiattle River Road to the Downey Creek campground and backpack the Downey Creek trail to Bachelor Creek. Bushwhack up Bachelor Creek to Cub Lake and Itswoot Ridge. From Itswoot Ridge traverse slopes below Spire Point and ascend the Dome Glacier to the Dome-Chickamin Col.
