Boulder Ridge (including the Gargoyles, Charlia Lakes, Cloudy Peak, Alphabet Ridge, and Warrior) and Home Lake / Constance Pass are readily accessed via the Buckhorn Wilderness Area (U.S. Forest Service) side of the Upper Dungeness River Trail and Marmot Pass.

Views of the east side of Mount Constance and Warrior are available from these roads (the lower portions of which are paved) which actually connect to FS 2800 and the Dungeness / Sequim area via the 5000-foot Bon Jon Pass.
