Natural Resource Lands in King County, Washington

Griffin Creek Natural Area

Griffin Creek Natural Area location mapThe Griffin Creek Natural Area covers about 46 acres of forestland in non-contiguous parcels, located between Carnation and Fall City. These sites are adjacent to the Carnation-Fall City Road (State Highway 203) and the Snoqualmie Valley Regional Trail. Griffin Creek, a King County Class I stream system, provides significant habitat for a number of salmonids including coho and steelhead, as well as some of the most concentrated coho spawning densities in the Snoqualmie River system. Griffin Creek Natural Area also provides low-impact passive recreation, interpretive and educational opportunities.

The northern parcel, over 27 acres of forest and former pasture lands, is bisected by the Snoqualmie Valley Regional Trail (SVT) and is directly adjacent to the Archdiocese of Seattle's Camp Don Bosco. This parcel's proximity to the creek, forest lands, and regional trail will provide excellent opportunities for habitat protection as well as for continued low-impact passive recreation. The 19-acre southern group of small holdings is roughly three-quarters of a mile upstream, isolated and undeveloped.
