The second highest peak of the Olympic Mountains, Deception climbing is described in the guidebook as "steep, exposed and quite serious". Early season climbing (before July 1) is strongly preferred to avoid what Smoot's guidebook calls "nightmarishly loose rock". This is NOT a casual walk up scramble peak, Camp in upper Royal Basin, about 1 mile above Royal Lake, for much better views, less bugs and fewer crowds. There are 2 good group camps sites here on large gravel bars, next to the tarn. A direct ascent of the NE gully route is the most straightforward, with about 5-6 pitches of 45-50 degree snow. A competent team can solo this with caution. Coming down this way would be . . . exciting. This peak can be easily combined with neighbor peak Mt. Mystery for a nice double on a 3 day weekend. Backcountry permits and bear cans are required in Olympic National Park. Ask for a permit in Upper Royal Basin, not Royal Lake. Bring treats for the nice backcountry rangers.
