Last week, heavy rains prompted DNR to close for the season the multiple-use mountain bike trails on Tiger Mountain. In the coming months, DNR will work with volunteers and partners from the mountain biking and hiking communities to improve these trails. You can help!

The first of many volunteer work parties, with our partners at the Evergreen Mountain Bike Alliance, will be from 9 a.m. to 4 p.m. on Sunday, November 7 at the Tiger Summit Trailhead. Volunteers will be working on the Preson RR Grade trail.  If you plan to attend, please sign up through Evergreen’s website.

More exciting volunteer opportunities coming this winter
The Evergreen Mountain Bike Alliance will continue to maintain the Preston Railroad Grade Trail through an Adopt-A-Trail agreement. The group will sponsor several work parties over the winter months. In addition, DNR and Evergreen will work together to reconstruct areas on the trail that have sustained damage from flowing water.

DNR and Evergreen will also be working with the Washington Trails Association (WTA) on an exciting project to re-route a significant section of the East Tiger Mountain Trail and extend the trail to the summit of 3,000-ft East Tiger Mountain. The existing trail is too steep and has sustained damage and erosion over the years. The newer, more sustainable trail will provide mountain bikers and hikers with a direct connection to the summit of East Tiger Mountain from the west end of the Preston RR Grade Trail. 

The East Tiger Mountain Trail project will begin once the Preston Railroad Grade Trail reconstruction project is completed.  Evergreen has agreed to maintain this new section of trail through an additional Adopt-A-Trail agreement with DNR. 

Evergreen and WTA will sponsor volunteer work parties for the East Tiger Mountain Trail project once the Preston Railroad Grade reconstruction project is completed.
