Taylor Mountain Forest

The King County Parks department acquired the 1800 acre Taylor Mountain Forest in 1997 and with the help of local trails groups has since been upgrading the environmental impact of the Forest's trails as well as public access to them.

The park itself contains a variety of trail types: gravel roads, broad flat gravel/dirt trails along former railroad beds, and narrow dirt hillside trails. While some areas can get quite muddy and other trails can be stony, a local chapter of Backcountry Horsemen of Washington keeps the trails maintained year-round and actual blockages are rare. Rides can include hilltops with spectacular views or fern-filled lowlands along a gurgling stream. You may spot remnants of long-past mining and logging efforts or more-recent logging along the trailsides. Elevations range from 500 to 2120 feet.

Taylor Mountain Forest is a wild forest; in addition to deer and the like, black bears and occasional cougars have been spotted in the area. Also, there are a few parcels of private land within the borders of the Forest and the City of Seattle’s Cedar River Watershed preserve along the eastern edge; please respect all private property signs and do not trespass.

Current Status Notes

Open; some trails closed for habitat restoration

Construction to expand the main parking lot will be ongoing from October 2015 through December 2015. Trails and logging roads are still open during construction, but you'll need to find parking elsewhere. A few spaces are available along the side of 276th Ave SE (Issaquah-Hobart Road), but the road is a busy one.

History Notes

  • A line of the Columbia & Puget Sound Railway ran through the south part of this area, serving clay and coal mines that existed within what is now the Cedar River Watershed.
