The first new mountain-bike trail built on Tiger Mountain in 20 years will open Wednesday.

The 1.4-mile East Tiger Summit Trail in Tiger Mountain State Forest, southeast of Issaquah, is a joint project of the Washington Department of Natural Resources (DNR) and Evergreen Mountain Bike Alliance, with assistance from volunteers and Washington Conservation Corps crews.

To get there, park at the Tiger Summit Trailhead at the summit of Highway 18 (Discover Pass required). Bike four miles along forest roads to the summit of East Tiger Mountain to reach the top of the new trail. Signs will be posted.

The trail begins at 3,000 feet, with southward views of Mount Rainier, and descends almost 500 feet through forests, ending at the top of Preston Railroad Grade Trail. Continue down Preston Railroad Grade trail, then follow 2.7 miles of forest road to the Northwest Timber Trail, which takes you back to the trailhead.

This week, save 90% on digital access.

The new trail will close for the season on Oct. 15.

DNR funding for the project came through Recreation and Conservation Office grants to build new, sustainable mountain-bike trails connecting existing trails on Tiger Mountain. Volunteers are sought to help build two additional mountain-bike trails in the area, with volunteer events planned weekly through September.
