The Friends of the Hylebos has been working with the community to protect and restore streams, wetlands, forests and open space in the Hylebos watershed since 1983. In 2011, Friends of the Hylebos joined forces with EarthCorps, a leading environmental restoration and community-building organization, and a long-time partner with more than a decade of experience helping to restore sites in the Hylebos watershed alongside The Friends.

EarthCorps - Friends of the Hylebos combines a passion for the beautiful outdoors with outreach and collaboration, and a knack for getting things done to carry out the work of keeping our community green and making our watershed a healthier place for people and for wildlife.

News and Observations from the West Hylebos Wetlands

West Hylebos Wetlands Park

The West Hylebos Wetlands Parks is open from dawn to dusk every day. The wetlands boardwalk is approximately 300 yards from the parking lot and wheelchair accessible.

The West Hylebos Wetlands is equal parts wildlife refuge, ecological and hydrological conservatory, nature trail, and just plain natural wonder. One of the last remaining bogs in South King County, Hylebos’ wetland wilderness lies just one mile west of I-5 in southern Federal Way. It's easy to reach and easy to explore this rare urban nature park.

Walking the park’s one-mile-long boardwalk immerses visitors in a forested wetlands that existed before Europeans settled the Puget Sound lowlands and affords a unique opportunity for nature study and reflection.

Wetlands are a hotbed of biodiversity as a trip to the West Hylebos illustrates. Hidden among the park’s 120 acres is a staggering diversity of life; from the tiny — 27 species of moss, 37 species of lichen, 30 fungi, and 6 liverwort species — to the gigantic — cathedral-like Douglas firs, western hemlock, red cedars, and rare ancient Sitka spruce that began life around the time the Mayflower reached Plymouth Rock.

More than one hundred bird species frequent the park, including gangly great blue herons, snazzy red pileated woodpeckers, orange-brown warblers, and violet green swallows.

Almost hidden by the activity above, the wetlands works its wonder on water flowing into the park through the many tributary streams. The wetlands slows and purifies this surface water, protecting Hylebos Creek and recharging the Redondo-Milton Channel Aquifer that supplies water to Federal Way, Milton, Fife, and Puyallup.


The entrance to the West Hylebos Wetlands is located at 411 S. 348th St. in Federal Way. Click here for Mapquest map.
