About the Park: 

North of the Enumclaw Plateau and about seven miles east of Auburn, the 1,140-acre Green River Natural Area is a gateway to the middle stretch of the Green River. Composed of steep valley walls and a broad valley floor, the natural area has 6.5 miles of multi-use trails.  Forests cover the upper slopes of the natural area while black cottonwoods line the river banks. The Green River is critical spawning and rearing habitat for coho, chum, Chinook salmon, and winter steelhead.

Park History:

The Green River Natural Area is comprised of the former Metzler, O'Grady, and Green River Parks all adjacent to the Green River. King County Department of Natural Resources and Parks (DNRP) acquired these parcels between 1973 and 2003 to protect critical salmon habitat protection with funds from a variety of sources including Waterways 2000 and Washington State Salmon Recovery Funds.
