About King County Parks

King County Parks has evolved from 150 acres in 1938 to more than 28,000 acres today. Our mission is to steward, enhance and acquire parks to inspire healthy communities. Per the 2002 business plan, which re-shaped the way Parks does business, we seek to cultivate strong relationships with non-profit, corporate and community partners to enhance park amenities for King County residents while reducing costs.

King County Parks is largely funded through a property tax levy, which the voters of King County approved on in August 2019 by more than 70 percent. The 2020-2025 Parks, Recreation Trails, and Open Space Levy will generate an estimated $810 million over six years through a CPI-indexed property tax levy lid lift of 18.32 cents per $1,000 of assessed value.

Today, our system consists of more than 200 parks175 miles of regional trails, and 215 miles of backcountry trails. From regional treasures such as Marymoor Park and Cougar Mountain Regional Wildland Park to amenities such as athletic fields, regional trails, and pools, there is something for everyone in King County Parks.

We hope you enjoy your time in King County's award-winning parks!
